Highlights of GAO-05-929, a report to congressional committees: 

Why GAO Did This Study: 

Concierge care is an approach to medical practice in which physicians 
charge their patients a membership fee in return for enhanced services 
or amenities. The recent emergence of concierge care has prompted 
federal concern about how the approach might affect beneficiaries of 
Medicare, the federal health insurance program for the aged and some 
disabled individuals. Concerns include the potential that membership 
fees may constitute additional charges for services that Medicare 
already pays physicians for and that concierge care may affect Medicare 
beneficiaries’ access to physician services. The Medicare Prescription 
Drug, Improvement, and Modernization Act of 2003 directed GAO to study 
concierge care and its relationship to Medicare. 

Using a variety of methods, including a nationwide literature search 
and telephone interviews, GAO identified 146 concierge physicians and 
surveyed concierge physicians in fall 2004. GAO analyzed responses from 
112 concierge physicians. GAO also reviewed relevant laws, policies, 
and available data on access to physician services and interviewed 
officials at the Department of Health and Human Services (HHS) and 
representatives of Medicare beneficiary advocacy groups. 

What GAO Found: 

Concierge care is practiced by a small number of physicians located 
mainly on the East and West Coasts. Nearly all of the 112 concierge 
physicians responding to GAO’s survey reported practicing primary care. 
Annual patient membership fees ranged from $60 to $15,000 a year, with 
about half of respondents reporting fees of $1,500 to $1,999. The most 
often reported features included same- or next-day appointments for 
nonurgent care, 24-hour telephone access, and periodic preventive care 
examinations. About three-fourths of respondents reported billing 
patient health insurance for covered services and, among those, almost 
all reported billing Medicare for covered services. 

Two principal aspects of concierge care are of interest to the Medicare 
program and its beneficiaries: compliance with Medicare requirements 
and its effect on beneficiary access to physician services. HHS has 
determined that concierge care arrangements are allowed as long as they 
do not violate any Medicare requirements; for example, the membership 
fee must not result in additional charges for items or services that 
Medicare already reimburses. Some concierge physicians reported to GAO 
that they would like more HHS guidance. The small number of concierge 
physicians makes it unlikely that the approach has contributed to 
widespread access problems. GAO’s review of available information on 
beneficiaries’ overall access to physician services suggests that 
concierge care does not present a systemic access problem among 
Medicare beneficiaries at this time. In comments on a draft version of 
this report, HHS agreed with GAO’s finding on concierge care’s impact 
on beneficiary access to physician services and indicated it will 
continue to follow developments in this area.

Concierge care is an approach to medical practice in which physicians 
charge their patients membership fees in exchange for enhanced services 
or amenities. Concierge physicians typically care for fewer patients 
than do doctors in conventional practice, and they are more readily 
available to member patients, for example, by cell phone or same-day 
appointments. The approach has attracted media attention in recent 
years. Critics contend that concierge care makes health care more 
lucrative for a few physicians and more convenient for some patients, 
but less accessible to patients who cannot or choose not to pay a 
membership fee. Proponents, in contrast, describe concierge care as 
both a rational response to patient demand for more personal care and a 
way for physicians to regain control of their medical practices and 
their lives. They say the approach allows concierge physicians to spend 
more time with their families, enhance their incomes, and spend more 
time on research and other professional activities. Because concierge 
care has gained attention only recently, little is known about how many 
concierge physicians there are or about how the approach could affect 
access to physician services. 

Concierge care has also generated attention within Congress, the 
Department of Health and Human Services (HHS), and state governments. 
Federal attention has centered on how membership fees might affect 
beneficiaries of Medicare, the federal health insurance program for 
individuals aged 65 and older and certain persons with disabilities. Of 
particular concern is the potential that membership fees may constitute 
additional charges for services that Medicare already pays physicians 
for and that concierge care may affect Medicare beneficiaries' access 
to physician services. Members of Congress introduced bills that, if 
enacted, would have prohibited physicians from imposing membership fees 
on Medicare beneficiaries as a condition for the provision of a 
Medicare-covered item or service.[Footnote 1] A few states are 
monitoring concierge care to ensure compliance with state insurance 
laws.[Footnote 2]

Given the concerns about how concierge care might affect Medicare 
beneficiaries, the Medicare Prescription Drug, Improvement, and 
Modernization Act of 2003 required us to study and report on the 
practice.[Footnote 3] As discussed with the committees of jurisdiction, 
this report addresses the following questions: 

1. What are the characteristics of concierge care?

2. What aspects of concierge care are of interest to the Medicare 
program and its beneficiaries?

To obtain information on the characteristics of concierge care, we 
surveyed concierge physicians about their practices and the types of 
services and financial arrangements they offer. Because no 
comprehensive directory of concierge physicians was available, we 
identified concierge physicians through a variety of methods, including 
a nationwide literature search, telephone interviews, and referrals 
from other concierge physicians. We identified as concierge physicians 
those who (1) had established a direct financial relationship with 
patients in the form of a membership or retainer fee and (2) provided 
enhanced services or amenities, such as same-day appointments or 
preventive services not covered by patient health insurance. We located 
a total of 146 concierge physicians practicing in the United States. We 
received survey responses from 112 physicians who practiced concierge 
care in October 2004. Because these 112 respondents were not selected 
at random from a larger population of known concierge physicians, the 
information they provided cannot be projected to any other concierge 
physicians. We did not attempt to verify the accuracy of their 
responses.[Footnote 4]

To review the aspects of concierge care that are of interest to the 
Medicare program and its beneficiaries, we reviewed documents and 
interviewed officials from two HHS entities responsible for 
administration and oversight of the Medicare program: the Centers for 
Medicare & Medicaid Services (CMS) and the Office of Inspector General 
(OIG). We also reviewed relevant sections of Medicare law and 
regulations; interviewed concierge physicians and their 
representatives; and in our survey, asked concierge physicians for 
their views on the guidance available from HHS on concierge care. To 
assess what is known about how concierge care may affect Medicare 
beneficiary access to physician services, we reviewed nationwide 
sources of information on Medicare beneficiaries' overall access to 
physician services, for example, reports by the Medicare Payment 
Advisory Commission. While we did not contact Medicare beneficiaries 
who were patients of physicians who converted to concierge practices, 
we contacted organizations that Medicare beneficiaries were likely to 
call with concerns or questions about concierge care, such as the 1- 
800-MEDICARE call line. We conducted our work in accordance with 
generally accepted government auditing standards from May 2004 through 
July 2005. 

Results in Brief: 

Concierge care is practiced by a small number of physicians located 
mainly on the East and West Coasts. Nearly all of the 112 concierge 
physicians who responded to our survey reported practicing primary 
care. They differed, however, on the characteristics of their concierge 
practices, such as the membership fee charged, features offered, and 
whether they billed patient health insurance. For example, the amount 
of the concierge care membership fee ranged from $60 to $15,000 a year 
for an individual, with about half of respondents charging individual 
annual membership fees of $1,500 to $1,999. The most frequently 
reported features offered by concierge physicians responding to our 
survey included same-or next-day appointments for nonurgent care, 24- 
hour telephone access, and periodic preventive-care physical 
examinations. In addition, about three-fourths of the respondents 
reported billing patient health insurance for covered services and, 
among those physicians, almost all reported billing Medicare for 
covered services. 

Two principal aspects of concierge care are of interest to the Medicare 
program and its beneficiaries: compliance with Medicare requirements 
and its effect on beneficiary access to physician services. HHS has 
determined that concierge care agreements are permitted as long as the 
arrangements do not violate any Medicare requirements; for example, the 
membership fee must not result in additional charges for items or 
services that are already reimbursed by Medicare. Various strategies 
for concierge care practice design have been developed to help 
concierge physicians avoid potential Medicare compliance problems, but 
most of our survey respondents expressed a need for more information 
from HHS to guide them. Although no national data directly address the 
impact of concierge care on beneficiaries' access to physicians, the 
information available as of 2004 on overall beneficiary access to 
services indicates that access has been good. The small number of 
concierge physicians makes it unlikely that the approach has 
contributed to widespread access problems. In addition, information 
from beneficiary advocacy organizations and on physician supply in 
communities where more concierge physicians practiced does not indicate 
that concierge care was contributing to any systemic access problems. 
In commenting on a draft of this report, HHS agreed with our finding 
about the effect of concierge care on Medicare beneficiary access to 
physician services, and also noted that it remains interested in 
concierge care and will continue to follow developments in the area. 

Background: 

Physician practices that charge membership or retainer fees and provide 
enhanced services or amenities are referred to as concierge care or 
retainer-based medicine.[Footnote 5] The origins of this practice 
approach are often traced to a medical practice founded in Seattle, 
Washington, in 1996. Physicians in this practice provide comprehensive 
primary care to no more than 100 patients each and currently charge 
annual retainer fees of $13,000 for individuals. These physicians do 
not bill any form of patient health insurance. As more physicians have 
begun concierge practices, concierge care has become more diverse, 
comprising physicians who bill patient insurance, charge lower 
membership fees, and see more patients than the original Seattle 
practice. 

The American Medical Association (AMA) has described concierge care as 
one of many options that patients and physicians are free to pursue. 
AMA in 2003 adopted ethics guidelines for physicians who have concierge 
care contracts--which AMA calls retainer contracts--with their 
patients.[Footnote 6] These guidelines specify, for example, that 
physicians should facilitate the transition to new physicians for 
patients who choose not to join their concierge practices and that they 
must observe relevant laws, rules, and contracts. 

The Medicare program was established by title XVIII of the Social 
Security Act, which governs how physicians bill for services that the 
program covers. Limits on what physicians may charge their Medicare 
patients depend on (1) the relationship between the physician and the 
Medicare program and (2) the type of service provided. 

Physicians who provide services to Medicare beneficiaries may choose 
one of three ways to relate to the program: participating, 
nonparticipating, or opted out. 

* Participating: Participating physicians agree to accept Medicare's 
fee schedule amount as payment in full for all covered services they 
provide to beneficiaries.[Footnote 7] In accordance with the Medicare 
participation agreement, these physicians receive reimbursement 
directly from the Medicare program and agree to charge beneficiaries 
only for any applicable deductible or coinsurance. More than 90 percent 
of the physicians and others who billed Medicare agreed to participate 
in Medicare in 2004.[Footnote 8]

* Nonparticipating: Nonparticipating physicians do not agree to accept 
the Medicare fee schedule amount paid to participating physicians as 
payment in full for all covered services they provide to beneficiaries. 
They are still subject to limits on what they may charge, however, and 
those limits depend on whether they seek reimbursement directly from 
Medicare. When a nonparticipating physician files a claim to be 
reimbursed directly from Medicare, he or she must accept the Medicare 
fee schedule amount for nonparticipating physicians, which is 95 
percent of the fee schedule amount for participating physicians, as 
payment in full and may charge the beneficiary only for any applicable 
Medicare coinsurance or deductible.[Footnote 9] When a nonparticipating 
physician does not request reimbursement directly from Medicare, he or 
she may charge the Medicare beneficiary up to 115 percent of the fee 
schedule amount for nonparticipating physicians.[Footnote 10]

* Opted-out: Physicians who opt out of Medicare are not subject to any 
limits on what they may charge their Medicare beneficiary patients, 
even for services that Medicare would otherwise cover.[Footnote 11] 
Physicians who opt out of Medicare must agree not to submit for 2 years 
any claims for reimbursement for any of the services they provide to 
Medicare beneficiaries.[Footnote 12] Contracts between opted-out 
physicians and their beneficiary patients allow them to make their own 
financial arrangements for services that would otherwise be covered by 
Medicare, effectively taking those services outside the program. These 
contracts must be in writing and they must clearly state that the 
beneficiary also agrees not to submit claims to Medicare and assumes 
financial responsibility for all services provided by that physician. 

In addition to a physician's Medicare participation status, the type of 
service provided also determines whether limits apply to physician 
charges. Physicians and beneficiaries are free to make private 
financial arrangements for the provision of services that Medicare does 
not cover. 

* General standard for Medicare coverage: Medicare law states that, to 
be covered, services must be reasonable and necessary for the diagnosis 
or treatment of illness or injury or to improve the functioning of a 
malformed body member.[Footnote 13] The scope of coverage and the exact 
type of service that may be reimbursed depend on the circumstances of 
each case. This medical necessity standard can result in situations 
where the same service--for example, a comprehensive office visit--is 
considered medically necessary and reimbursable by Medicare in some 
circumstances but not others. 

* Specific inclusion in Medicare coverage: Medicare law also 
establishes coverage for certain specific services. For example, 
Medicare covers an initial preventive physical examination for 
beneficiaries who become eligible for Medicare on or after January 1, 
2005. Other examples of specific preventive benefits established by 
statute include immunizations against pneumonia, hepatitis B, and 
influenza and periodic screening tests for early detection of certain 
cancers. 

* Specific exclusion from Medicare coverage: Medicare law specifically 
excludes certain items or services--for example, personal comfort 
items, purely cosmetic surgery, hearing aids, and routine physical 
checkups except for the initial preventive examination for newly 
eligible beneficiaries. 

Table 1 summarizes the limits on physician charges depending on their 
Medicare participation status and the type of service provided. 

Table 1: Limits on Physician Charges for Medicare-Covered Services: 

Physician status: Participating; 
Medicare-covered services: Medically necessary items or services and 
specific preventive or other benefits; 
Limits on physician charges: Medicare fee schedule amount for 
participating physicians. The beneficiary may be charged applicable 
deductible and coinsurance only. 

Physician status: Nonparticipating; 
Medicare-covered services: Medically necessary items or services and 
specific preventive or other benefits; 
Limits on physician charges: Reimbursement claimed directly from 
Medicare: Medicare fee schedule amount for nonparticipating physicians, 
which is 95 percent of the amount for participating physicians. The 
beneficiary may be charged applicable deductible and coinsurance only; 
Reimbursement not claimed directly from Medicare: No more than 115 
percent of the Medicare fee schedule amount for nonparticipating 
physicians. The beneficiary may be charged this entire amount and may 
be reimbursed 80 percent of the fee schedule amount for 
nonparticipating physicians. 

Physician status: Opted-out; 
Medicare-covered services: None, except when emergency or urgent care 
is provided to a beneficiary with whom the physician does not have a 
contract.[A]; 
Limits on physician charges: No statutory limits apply. The amount of 
payment is determined by contracts between physicians and patients. 

Source: GAO analysis. 

[A] Items or services provided by opted-out physicians to their 
beneficiary patients under private contracts are not covered by 
Medicare. 

[End of table]

Physicians who impose charges on beneficiaries beyond the Medicare 
limits may be subject to civil monetary penalties.[Footnote 14] The 
Secretary of HHS has delegated enforcement of Medicare limits to two 
different entities within HHS. CMS, which administers the Medicare 
program, has enforcement authority over the limits that apply to 
nonparticipating physicians. HHS OIG has enforcement authority over 
participating physicians' compliance with the terms of the 
participation agreement. 

The Medicare law's limits on physician charges protect beneficiaries 
from additional charges for services they are entitled to receive under 
Medicare. The law does not, however, provide that a beneficiary has the 
right to receive services from any particular physician. Physicians are 
free to choose how they will interact with the Medicare program. They 
may decide to close their practices to new Medicare patients or decline 
to treat any Medicare beneficiaries at all. 

Characteristics of Concierge Care: 

Concierge care is practiced by a small number of physicians, located 
primarily in urban areas on the East and West Coasts. Although nearly 
all of the concierge physicians who responded to our survey reported 
practicing primary care, they differed in many of the characteristics 
of practice design, including the annual membership fee charged, number 
of patients treated, features offered, whether they billed health 
insurance, and their relationship to the Medicare program. 

Concierge Physician Location and Specialty: 

Concierge physicians are few in number and located primarily in urban 
areas on the East and West Coasts. Since the first Seattle practice was 
founded in the mid-1990s, the number of concierge physicians has been 
rising but remains small. We were able to locate 146 concierge 
physicians in the United States as of 2004--a small number compared 
with the more than 470,000 physicians who regularly submitted claims to 
Medicare in 2003.[Footnote 15] The 146 concierge physicians we 
identified practiced in 25 states, with the greatest numbers in 
metropolitan areas on the East and West Coasts.[Footnote 16] California 
had the highest number, with 26 concierge physicians, followed by 
Florida with 22, Washington with 21, and Massachusetts with 17. We 
identified 1 to 8 concierge physicians in 21 other states, though most 
of these other states had 5 or fewer. All but 2 of the concierge 
physicians we located practiced in metropolitan areas. We found the 
highest numbers of concierge physicians in the metropolitan statistical 
areas (MSA)[Footnote 17] of Seattle (19); Boston (17); and West Palm 
Beach-Boca Raton, Florida (13). Figure 1 presents the locations of 144 
concierge physicians we identified who practiced in MSAs throughout the 
nation.[Footnote 18]

Notes: This figure presents the practice locations of the 144 concierge 
physicians we identified who were located in MSAs. It does not include 
the 2 physicians located outside MSAs. We did not identify any 
concierge physicians in Alaska or Hawaii. 

[End of figure] 

The number of physicians practicing concierge care has increased in 
recent years. Among the 112 concierge physicians who responded to our 
survey, the cumulative total number practicing concierge care has 
increased by: 

more than 10 times in the past 5 years (see fig. 2).[Footnote 19] About 
two-thirds of the responding physicians reported that they began to 
practice concierge care in 2003 or later. The number of responding 
physicians starting to practice concierge care rose each year after 
2000, except in 2004, although we did not include physicians who began 
practicing concierge care after October 2004.[Footnote 20]

Figure 2: Yearly Growth in Number of Concierge Physicians: 

[See PDF for image] 

Notes: n = 112 concierge physicians practicing as of October 2004. Data 
for 2004 do not include physicians who began practicing concierge care 
after October. The earliest year in which a physician in our survey 
reported beginning to practice concierge care was 1997. 

[End of figure] 

Nearly all of the physicians who responded to our survey reported 
practicing primary care and most were not new to medical practice. 
Physicians reported practicing the primary care disciplines of internal 
medicine (about three-fourths of respondents) and family practice 
(about one-fourth of respondents). Survey respondents reported being in 
various stages in their medical careers, from relatively new to 
practice to decades of experience. More than two-thirds reported having 
been in medical practice for 15 years or more. The average length of 
time in medical practice was 19 years, and about one-fourth of the 
respondents reported being in practice for 25 years or more. See 
appendix II for additional information provided by survey respondents. 

Characteristics of Practice Design among Surveyed Concierge Physicians: 

Concierge physicians responding to our survey reported a variety of 
practice characteristics. These included the amount charged to be a 
concierge patient, practice size, features offered, whether they billed 
patient health insurance, and their relationship to the Medicare 
program.[Footnote 21]

Amount of Annual Membership Fee: 

The annual membership fee for an individual to join a concierge 
practice ranged from $60 to $15,000 among the physicians responding to 
our survey. As shown in figure 3, more than 80 percent of respondents 
reported annual fees from $500 to $3,999; the most frequently reported 
annual fee was $1,500. Three-fourths of our respondents reported that 
they waived the membership fee for some of their concierge 
patients.[Footnote 22] About one in eight of these physicians reported 
waiving the fees for 20 percent or more of their concierge patients. 

Figure 3: Annual Membership Fee for Individuals, October 2004: 

[See PDF for image] 

Notes: n = 111 concierge physicians practicing as of October 2004; 1 
respondent did not provide this information. The maximum reported 
annual individual membership fee charged was $15,000. 

[End of figure] 

Practice Size: 

Concierge physicians responding to our survey reported, on average, 491 
patients under their care as of October 2004--significantly fewer than 
the average of 2,716 patients they reported for the year before 
beginning to practice concierge care. Of the total patients they 
reported in October 2004, an average of 326 were concierge patients-- 
that is, patients who either paid the membership fee or had the fee 
waived, and were offered the enhanced services or amenities associated 
with membership. 

Nearly two-thirds of responding physicians reported having fewer than 
400 concierge patients (see fig. 4). Concierge physicians also reported 
seeing fewer patients per day: the average number of patients 
physicians reported seeing on a typical day fell to 10 in October 2004 
from 26 in the year before they began practicing concierge 
care.[Footnote 23]

Figure 4: Number of Concierge Patients under the Care of Individual 
Concierge Physicians, October 2004: 

[See PDF for image] 

Notes: n = 109 concierge physicians practicing as of October 2004; 3 
respondents did not provide this information. The maximum reported 
number of concierge patients was 980. 

[End of figure] 

Many respondents reported that they were still establishing their 
concierge practices and had set targets for the number of concierge 
patients in their care. Respondents reported target numbers for 
concierge patients ranging from 10 to 1,300; the two most frequently 
reported goals were 300 and 600 concierge patients (reported by 23 and 
30 respondents, respectively). About 80 percent of respondents reported 
that they had not yet reached their target number of concierge patients 
as of October 2004. About 1 in 2 of the respondents who began concierge 
care in 2001 or earlier reported having met their goal for the number 
of concierge patients in their practices, compared with about 1 in 7 of 
those who reported starting their concierge practices on or after 
January 1, 2002. 

Concierge physicians may continue, for various reasons, to treat some 
nonconcierge patients. Thirty-six, about one-third of survey 
respondents, reported that their individual practices included some 
nonconcierge patients, while about two-thirds had practices consisting 
entirely of concierge patients. Physicians who continued to see 
nonconcierge patients reported doing so for various reasons: to ensure 
continuity of care for patients who did not join the concierge 
practice, to maintain a combined concierge and conventional practice, 
or to see patients as part of a subspecialty practice.[Footnote 24] 
Less frequently reported situations in which respondents reported 
seeing nonconcierge patients included seeing family members of their 
concierge patients occasionally as a courtesy or when urgent needs 
arose, and covering for other doctors who were out of town. 

Features Offered: 

The concierge physicians responding to our survey reported offering a 
variety of features, some of which were offered by nearly all the 
respondents, others by relatively few (see table 2). The most 
frequently reported features were same-or next-day appointments for 
nonurgent care, 24-hour telephone access, and periodic preventive-care 
physical examinations.

When asked to list the most important features of concierge care that 
were not routinely available to their nonconcierge patients, 
respondents most frequently cited features related to increased time 
spent with patients, direct patient access to the physician at any 
time, same-or next-day appointments, and comprehensive preventive and 
wellness care. 

Interaction with Patient Health Insurance and Medicare: 

Concierge physicians responding to our survey reported different ways 
of interacting with patient health insurance and the Medicare program. 
Eighty-five, approximately three-fourths, of respondents reported that 
they billed patient health insurance for covered services. Of these 85 
physicians, 79 reported they billed Medicare and 6 reported they did 
not. About one-fourth of the concierge physicians responding to our 
survey reported that they did not submit any claims to patient health 
insurance, including Medicare. 

About three-fourths of our survey respondents reported that they were 
Medicare participating physicians, and about one-fifth had opted out of 
Medicare as of October 2004 (see fig. 5). Nationwide, relatively few 
physicians--approximately 3,000 in 2004--have opted out of the Medicare 
program.

Aspects of Concierge Care of Interest to Medicare and Its 
Beneficiaries: 

Two principal aspects of concierge care are of interest to the Medicare 
program and its beneficiaries: its compliance with Medicare 
requirements and its effect on beneficiary access to physician 
services. HHS has established general policy on concierge care and 
alerted physicians to areas of potential noncompliance. Although 
concierge physicians have followed various strategies to ensure 
compliance with Medicare requirements, most physicians responding to 
our survey indicated more HHS guidance would be helpful. Available 
measures of access to care as of 2004, while not directly addressing 
concierge care, indicate that Medicare beneficiary access to physician 
services has been good. The small number of concierge physicians makes 
it unlikely that the approach has contributed to widespread access 
problems. 

Compliance with Medicare Requirements: 

HHS has established general policy on concierge care and has alerted 
physicians to areas of potential noncompliance. Concierge physicians 
have expressed the need for additional guidance and have taken various 
steps--such as structuring their practices in an attempt to avoid 
associating their membership fees with Medicare-covered services or 
opting out of Medicare--to avoid compliance problems. 

CMS outlined its position on concierge care in a March 2002 memorandum 
to CMS regional offices that CMS officials told us remains current as 
of June 2005. The memorandum states that physicians may enter into 
retainer agreements with their patients as long as these agreements do 
not violate any Medicare requirements.[Footnote 25] For example, 
concierge care membership fees may constitute prohibited additional 
charges if they are for Medicare-covered items or services. If so, a 
physician who has not opted out of Medicare would be in violation of 
the limits on what she or he may charge patients who are Medicare 
beneficiaries.[Footnote 26]

HHS OIG has addressed the consequences of noncompliance with Medicare 
billing requirements. In March 2004, HHS OIG issued an alert "to remind 
Medicare participating physicians of the potential liabilities posed by 
billing Medicare patients for services that are already covered by 
Medicare."[Footnote 27] The alert stated that "charging extra fees for 
already covered services abuses the trust of Medicare patients by 
making them pay again for services already paid for by Medicare."As an 
example, the alert referred to a Minnesota physician who paid a 
settlement and agreed to stop offering personal health care contracts 
to patients for annual fees of $600. According to HHS OIG, these 
contracts included at least some services that were already covered and 
reimbursable by Medicare. The alert advised participating physicians 
that they could be subject to civil monetary penalties if they 
requested payment from Medicare beneficiaries for those services in 
addition to the relevant deductibles and coinsurance charged for these 
services. In addition, the alert noted that nonparticipating physicians 
may also be subject to penalties for overcharging beneficiaries for 
covered services. 

Unless a concierge physician opts out of Medicare, the question of 
Medicare coverage is central to whether a concierge care agreement 
complies with the program's limits on patient charges. HHS OIG's March 
2004 alert provided three examples of services offered by the physician 
in Minnesota: coordination of care with providers, a comprehensive 
assessment and plan for optimum health, and extra time spent on patient 
care. HHS OIG did not indicate which, if any, of those three services 
were already covered by Medicare. The resulting uncertainty, about 
which features of the Minnesota physician's concierge agreement formed 
the basis for HHS OIG's allegation that he violated the Medicare 
program's prohibition against charging beneficiaries more than the 
applicable deductible and coinsurance, generated concern among some 
concierge physicians. 

According to HHS OIG officials, HHS OIG has not issued more detailed 
guidance on concierge care because its role in this area is to carry 
out specific delegated enforcement authorities, not to make policy. HHS 
OIG addresses each situation in its specific context. Physicians with 
questions about their own concierge care agreements may obtain guidance 
specific to them from HHS by requesting an advisory opinion. HHS OIG's 
Industry Guidance Branch issues advisory opinions on matters that fall 
within its enforcement authority. It covers provisions of Medicare law 
that prohibit knowingly presenting a beneficiary with a request for 
payment in violation of a physician's participation agreement.[Footnote 
28] Consequently, any participating physician who operates or is 
considering starting a concierge practice could request an advisory 
opinion. Advisory opinions are legally binding on HHS and the 
requesting party as long as the arrangement is consistent with the 
facts provided. The process involves a written request that meets 
certain requirements, plus a fee. Advisory opinions are not available 
for hypothetical situations, "model" situations, or general questions 
of interpretation. Officials with HHS OIG reported that as of May 2005, 
the Industry Guidance Branch had received very few inquiries regarding 
advisory opinions about concierge care agreements, and no opinions have 
been issued on this subject. 

Most of the physicians who responded to our survey indicated that more 
guidance from HHS on how Medicare requirements might affect concierge 
care is needed. Although about one-fourth of respondents said that the 
information available from HHS was clear and sufficient, more than half 
reported that it was not. Of those who reported that the guidance was 
not clear and sufficient, about one-third stated that information was 
available from other sources, including private attorneys, the Society 
for Innovative Medical Practice Design, and concierge care consultants 
(see table 3).

[End of table]

Medicare compliance is an important consideration in how concierge 
physicians set up their practices. For example, concierge physicians 
should avoid including services covered by Medicare in their concierge 
agreements to ensure that no additional charges are associated with 
those services. Different strategies have been undertaken to accomplish 
this. One such strategy emphasizes the convenience and availability of 
concierge physicians as the primary benefit of membership. Another 
strategy is to focus on preventive care, linking the membership payment 
only to screening that Medicare does not cover. Some concierge 
physicians opt out of Medicare, thus avoiding potential compliance 
problems; opting out requires physicians to forgo all Medicare 
reimbursement for 2 years. 

Information on Medicare Beneficiary Access to Physician Services: 

Most of the concierge physicians responding to our survey reported 
having patients who were Medicare beneficiaries; however, the numbers 
of beneficiary patients they reported as part of their concierge and 
previous nonconcierge practices are very small compared to the more 
than 40 million Medicare beneficiaries. Surveys and national sources of 
information on beneficiary access to care do not address the impact of 
concierge care directly. In the absence of direct measures of the 
impact of concierge care on Medicare beneficiaries' access to physician 
services, we reviewed available nationwide data and other indicators 
about beneficiaries' experiences overall. These sources showed that 
overall access to physician services has not changed substantially in 
recent years. 

Medicare Beneficiary Patients of Surveyed Concierge Physicians: 

Estimates provided by 105 of the respondents indicated that about two- 
thirds of the estimated 19,400 Medicare beneficiaries who were patients 
of these physicians in October 2004 were considered concierge 
patients.[Footnote 29] The rest were nonconcierge patients who were 
neither charged a fee nor offered enhanced services. Physicians who 
continued to see nonconcierge patients reported doing so for various 
reasons, including to ensure continuity of care for individuals who had 
not yet found a new physician and to maintain a practice consisting of 
both concierge and nonconcierge patients. 

On average, Medicare beneficiaries represented about 35 percent of the 
total number of patients--concierge and nonconcierge--that responding 
concierge physicians reported having in their care as of October 2004. 
Eight of the 105 physicians who provided this information reported 
having no Medicare beneficiaries in their practices at all; 36 reported 
treating some, but fewer than 100 Medicare beneficiaries among their 
patients; and 12 reported having 400 or more Medicare beneficiaries 
under their care (see fig. 6). 

Figure 6: Medicare Beneficiary Patients of Concierge Physicians, 
October 2004: 

[See PDF for image] 

Notes: n = 105 concierge physicians as of October 2004; 7 respondents 
did not provide this information. Includes Medicare beneficiaries who 
were nonconcierge patients of concierge physicians. The highest number 
of Medicare beneficiary patients reported was 2,825. 

[End of figure] 

Concierge physicians who responded to our survey reported that, on 
average, Medicare beneficiaries in their previous nonconcierge 
practices joined their concierge practices in about the same proportion 
as their patients overall. When physicians begin practicing concierge 
care, existing patients may choose not to become concierge patients. 
Patient counts provided by responding physicians indicate that, on 
average, Medicare and non-Medicare patients who were under their care 
before they began concierge care chose to join as concierge patients in 
roughly similar proportions. 

Table 4 shows the average numbers of Medicare and non-Medicare patients 
responding physicians reported were in their practices before and after 
their conversion to concierge care. The numbers of beneficiaries that 
responding concierge physicians reported in their practices are 
relatively small--for example, the total number of Medicare 
beneficiaries that 88 responding physicians reported treating before 
conversion to concierge care was fewer than 100,000--compared to the 
nation's more than 40 million Medicare beneficiaries. 

Table 4: Patients from Physicians' Conventional Practices Who Joined 
Physicians' Concierge Practices: 

Status of practice: Before conversion to concierge care; 
Average number of patients: Total: 2,716 (n = 97); 
Average number of patients: Medicare: 1,069 (n = 88); 
Average number of patients: Non-Medicare: 1,632 (n = 88). 

Status of practice: After conversion to concierge care; 
Average number of patients: Total: 301 (n = 94); 
Average number of patients: Medicare: 138 (n = 85); 
Average number of patients: Non-Medicare: 157 (n = 85). 

Source: GAO survey of concierge physicians. 

Notes: Although there were 112 unique respondents who practiced 
concierge care in October 2004, not all respondents answered each 
question. This table presents information about the patients who became 
members of the physicians' concierge practices. It does not count 
individuals who may have remained under the care of their physicians as 
nonconcierge patients. 

[End of table]

Respondents reported engaging in a variety of activities to help 
Medicare beneficiaries choosing not to join the physician's concierge 
practice find new physicians. These activities included designating a 
staff person to help with transition questions, referring patients to 
other physicians within a group practice, calling new physicians to 
discuss a patient's medical history, and remaining available to treat 
all patients until they had found a new primary care physician. 
Additional activities reported include bringing a new physician into 
the practice to take on the concierge physician's previous patients and 
speaking individually with each patient. We did not contact Medicare 
beneficiary patients of the concierge physicians in our survey to 
determine how many of them had sought or found new physicians. See 
appendix II for additional details on actions physicians reported 
taking to help Medicare patients who did not join their concierge 
practices to find new physicians. 

Nationwide and Community Indicators of Beneficiaries' Access: 

The number of concierge physicians, and the number of Medicare 
beneficiaries the physicians reported in their previous nonconcierge 
practices, are relatively small, and therefore national surveys of 
samples of Medicare beneficiaries are not likely to include many 
beneficiaries who come into contact with concierge care. In the absence 
of data to directly assess the impact of concierge care on Medicare 
beneficiaries' access, however, national surveys can provide general 
information about the availability of physicians and beneficiary access 
to care. Overall, national surveys showed that Medicare beneficiary 
access to physician services has been good, in some cases better than 
access for individuals with private health insurance. 

Surveys targeting both Medicare beneficiaries and physicians revealed 
that overall access to physician services has not changed substantially 
in recent years. Most beneficiaries surveyed reported that they have 
not had a problem finding a primary care physician. Of those who did 
report a problem, only a small percentage attributed their difficulty 
to physicians' refusing to take new Medicare patients. Most 
beneficiaries attributed problems to transportation barriers or their 
difficulty finding a physician they liked, not to a shortage of primary 
care physicians who accepted Medicare. Of physicians surveyed, most 
reported accepting at least some new Medicare patients.[Footnote 30] 
Analysis done by the Medicare Payment Advisory Commission of Medicare 
claims data also revealed that the number of physicians who treated 
Medicare patients grew at a more rapid pace than the Medicare 
beneficiary population from 1999 to 2003.[Footnote 31] Results from our 
review of Medicare claims data from April 2000 and April 2002 indicated 
increases throughout the country in both the percentage of 
beneficiaries who received physician services and the number of 
services provided to beneficiaries who were treated.[Footnote 32]

Physician supply data from the Seattle, Boston, and Southeast Florida 
metropolitan areas, where we found concierge care is relatively 
prominent, suggested that physicians there were relatively plentiful. 
The ratio of physicians to overall population in each of these 
metropolitan areas exceeded the nationwide average for all metropolitan 
areas in 2001. Because concierge physicians treat fewer patients than 
do physicians in conventional practices, a community needs other 
available physicians to take on Medicare beneficiaries who choose not 
to join a concierge practice. Even in communities where the concierge 
physician population was largest, however, the number of concierge 
physicians we identified was small compared with the physician 
population as a whole. 

Information about Experiences of Individual Beneficiaries: 

CMS officials informed us that CMS has not established a special 
tracking system for beneficiary complaints about concierge care because 
the practice is not sufficiently widespread to raise concerns about 
access to care. Similarly, officials with call centers for 1-800- 
MEDICARE and CMS contractors handling beneficiary inquiries and 
complaints reported that they have received a small number of calls 
from beneficiaries about concierge care. Because of the low volume of 
calls on this subject, the majority of these call centers do not have 
tracking codes for responses to calls about concierge care.[Footnote 
33] Of the 15 CMS contractors who process claims for physician services 
and responded to our inquiry, only 1 reported establishing a code to 
track concierge care inquiries.[Footnote 34] This contractor 
established the tracking code in response to our inquiry about 
concierge care in February 2005.[Footnote 35] As of April 2005, none of 
this contractor's call centers reported receiving any beneficiary calls 
about concierge care. 

Because of the relatively high number of concierge physicians in the 
Seattle metropolitan area, CMS's Seattle regional office has been 
following concierge care, but so far it has not identified an impact in 
Medicare beneficiaries' access to care. The Seattle office's efforts 
are part of an agencywide effort to monitor beneficiary access to care 
through reports in the media and from the CMS divisions that interact 
with beneficiaries. According to CMS officials in the agency's Seattle 
regional office, that office has received a small number of calls about 
concierge care from physicians and beneficiaries, mainly asking whether 
concierge care is permitted under Medicare law. Seattle regional office 
officials said they respond in accordance with CMS guidelines: they do 
not review specific concierge care agreements but help beneficiaries by 
providing a list of local physicians who participate in Medicare. The 
CMS Seattle regional office has not found indications that 
beneficiaries who choose not to pay their physician's membership fees 
have had problems locating new primary care physicians. 

We did not contact Medicare beneficiaries who were patients of 
physicians who converted to concierge care to determine how many of 
them had sought or found new physicians. We did, however, contact 
organizations that Medicare beneficiaries might call with problems or 
concerns,

including AARP and the Medicare Rights Center.[Footnote 36] Like CMS, 
officials with these organizations reported receiving a few calls from 
beneficiaries about concierge care, and none reported complaints from 
beneficiaries about finding a physician or about access to services 
because of concierge care. Officials with these groups also reported 
that they have not developed a formal system to track the issue. 
According to officials from these organizations, calls from 
beneficiaries about concierge care are usually requests for help 
interpreting the letters from their physicians explaining the 
physicians' conversion to concierge care. 

Concluding Observations: 

Although the number of physicians practicing concierge care has grown 
in recent years, the total number remains very small. Available 
measures of Medicare beneficiaries' overall access to care, while not 
directly addressing concierge care, indicate widespread availability of 
physicians to treat them. The small number of concierge physicians at 
the time of our review, along with information from available measures 
of access to services, suggests that concierge care does not present a 
systemic access problem for Medicare beneficiaries at this time. 

Agency and Other Comments: 

We provided a draft of this report for comment to HHS. In its comments, 
HHS agreed that concierge care has had a minimal impact on beneficiary 
access to physician services at this time. HHS noted, however, that the 
agency is interested in developments in concierge care and will 
continue to follow this area and to evaluate whether any further steps 
are indicated. See appendix III for HHS's written comments. HHS also 
provided technical comments, which we incorporated where appropriate. 

We also provided a draft to the Society for Innovative Medical Practice 
Design, formerly the American Society of Concierge Physicians, which 
had no comments. 

We are sending copies of this report to the Secretary of HHS, the 
Inspector General of HHS, the Administrator of CMS, and appropriate 
congressional committees. We will also provide copies to others upon 
request. In addition, the report is available at no charge on the GAO 
Web site at [Hyperlink, http://www.gao.gov].

Appendixes: 

Appendix I: Scope and Methodology: 

To obtain information on the characteristics of concierge care, we 
surveyed concierge physicians about their practices and the types of 
services and financial arrangements they offer. Because no 
comprehensive directory of concierge physicians was available, we 
compiled our own list of concierge physicians to survey. We focused our 
survey on physicians who, as of October 2004, (1) had established a 
direct financial relationship with patients in the form of a membership 
or retainer fee and (2) provided enhanced services or amenities, such 
as same-day appointments or preventive services not covered by patient 
health insurance.[Footnote 37]

We identified concierge physicians through a variety of methods, 
including a nationwide literature search, telephone interviews, and 
referrals from other concierge physicians. With the assistance of a 
contractor, we compiled an initial list of potential survey 
participants, contacted them to confirm that they met the criteria for 
inclusion in our survey, and requested referrals to additional 
concierge physicians. We used a variety of sources to establish our 
initial list of potential survey participants, including a nationwide 
Internet search of articles in newspapers, business journals, and 
medical publications; attendance at the first annual meeting of the 
American Society of Concierge Physicians (now known as the Society for 
Innovative Medical Practice Design); and a list of physicians 
affiliated with a consulting firm that helps physicians establish and 
maintain concierge practices. This process yielded a final mailing list 
of 187 individuals. 

We mailed the questionnaires in November 2004, after pretesting it with 
concierge physicians and incorporating suggestions from several 
reviewers familiar with concierge care; we followed up with 
nonrespondents during December 2004 and January 2005. Two 
questionnaires were returned as undeliverable; we removed those names 
from our total count of potential concierge physicians. The total we 
used to calculate the response rate for our survey was therefore 185. 

We received responses to our survey from 129 physicians, yielding an 
overall response rate of 70 percent. Of the respondents, 112 physicians 
confirmed that they practiced concierge care--that is, they reported 
that they charged a retainer or membership fee for enhanced services or 
amenities--as of October 2004. We analyzed only the information 
provided by these 112 physicians. Because these 112 respondents were 
not randomly sampled from a larger population of known concierge 
physicians, the information they provided cannot be projected to any 
other concierge physicians. We did not attempt to verify the accuracy 
of their responses. 

In addition to the 112 physicians practicing concierge care in October 
2004 and responding to our survey, we confirmed--through, for example, 
telephone interviews conducted by us or our contractor--the concierge 
status of an additional 34 physicians who did not return our 
questionnaire. This process yielded a total of 146 confirmed concierge 
physicians. To analyze the geographic practice locations of these 146 
physicians, we assigned the physicians' zip codes to larger geographic 
units called metropolitan statistical areas (MSA) or primary 
metropolitan statistical areas (PMSA), as defined in 1999 by the Office 
of Management and Budget. 

To review the aspects of concierge care of interest to the Medicare 
program and its beneficiaries, we reviewed relevant provisions of 
Medicare law and documents from the Department of Health and Human 
Services (HHS), including Centers for Medicare & Medicaid Services 
(CMS) policy manuals and internal memorandums, information posted on 
the CMS Web site, an alert published by the HHS Office of Inspector 
General (OIG), and correspondence between interested parties and HHS 
officials regarding concierge care. We also interviewed CMS officials 
at CMS headquarters and in the Seattle regional office, officials with 
HHS OIG, and concierge physicians and their representatives and, in our 
survey, asked concierge physicians for their views on the guidance 
available from HHS on concierge care. 

To assess what is known about how concierge care might affect Medicare 
beneficiary access to physician services, we reviewed national surveys 
and reports on overall Medicare beneficiary access. Because so few 
physicians and beneficiaries are affected by concierge care, concierge 
physicians or their patients are unlikely to be randomly chosen to 
participate in surveys on access to physicians by Medicare 
beneficiaries. National surveys and analysis on beneficiary access to 
physician services are also not sufficiently detailed to address 
concierge care, but they can provide information about physician 
availability and beneficiary access to care overall. The sources we 
consulted targeted beneficiaries, physicians, or both and included the 
following:

Because concierge physicians generally treat fewer patients than 
physicians in conventional practices, we assessed community-level data 
on physician supply to see if other physicians might be available to 
take on Medicare beneficiaries who choose not to join a concierge 
practice. We calculated physician-to-population ratios in communities 
where we found the highest numbers of concierge physicians and compared 
them to the average ratio for all metropolitan areas in the United 
States. To calculate this ratio, we used data from a 2003 HHS Health 
Resources and Services Administration database known as the Area 
Resource File. This database included county-level data on active, 
nonfederal, office-based, patient-care physicians from the 2001 
American Medical Association Physician Masterfile database and county- 
level resident population data from the U.S. Census Bureau for 2001, 
which we aggregated by MSA and PMSA. 

We did not contact Medicare beneficiaries who were patients of 
physicians who converted to concierge practices. We obtained 
information from organizations likely to receive calls from Medicare 
beneficiaries to determine whether individual beneficiaries were 
reporting concerns about concierge care or difficulty finding new 
physicians. We obtained and analyzed information from officials at CMS, 
call centers for 1-800-MEDICARE, and 15 of 18 CMS contractors that 
process Medicare claims for outpatient physician services. We spoke 
with representatives of AARP, the American Bar Association's Commission 
on Law and Aging, the Center for Medicare Advocacy, the Health 
Assistance Partnership of Families USA, and the Medicare Rights Center. 

We conducted our work in accordance with generally accepted government 
auditing standards from May 2004 through July 2005.

Appendix II: Summary of Physician Responses to GAO Concierge Care 
Survey: 

This appendix summarizes the results from questions we asked physicians 
who practiced concierge care as of October 2004. We sent surveys to 185 
physicians with valid addresses whom we had identified as potential 
concierge physicians. We obtained responses from 129 individuals, for 
an overall response rate of 70 percent, and analyzed the responses from 
112 physicians who practiced concierge care in October 2004. 

The following tables and figures present information on reported 
characteristics of the 112 concierge physicians who responded to our 
survey and their practice settings (table 5), the estimated number of 
patients in their individual practices (table 6), goals for the total 
number of concierge patients when physicians' practices are fully 
established (fig. 7), annual membership fees charged by physicians who 
did and did not bill insurance (fig. 8), actions concierge physicians 
reported taking to help Medicare beneficiaries who did not join their 
concierge practices find new physicians (table 7), concierge 
physicians' views on the sufficiency of HHS guidance on concierge care 
and Medicare (table 8), and concierge physicians' views on remaining in 
medical practice and treating Medicare beneficiaries if concierge care 
were not an option (table 9).

Appendix III: Comments from the Department of Health and Human 
Services: 

DEPARTMENT OF HEALTH & HUMAN SERVICES: 
Office of Inspector General:

JUL 19 2005:

Mr. A. Bruce Steinwald: 
Director, Health Care:
U.S. Government Accountability Office: 
Washington, DC 20548:

Dear Mr. Steinwald:

Enclosed are the Department's comments on the U.S. Government 
Accountability Office's (GAO's) draft report entitled, "PHYSICIAN 
SERVICES: Concierge Care Characteristics and Considerations for 
Medicare" (GAO-05-776). The comments represent the tentative position 
of the Department and are subject to reevaluation when the final 
version of this report is received.

The Department provided several technical comments directly to your 
staff.

The Department appreciates the opportunity to comment on this draft 
report before its publication. 

Sincerely,

Signed by: 

Daniel R. Levinson:
Inspector General:

Enclosure:

The Office of Inspector General (OIG) is transmitting the Department's 
response to this draft report in our capacity as the Department's 
designated focal point and coordinator for U.S. Government 
Accountability Office reports. OIG has not conducted an independent 
assessment of these comments and therefore expresses no opinion on them.

HHS COMMENTS ON THE U.S. GOVERNMENT ACCOUNTABILITY OFFICE'S DRAFT 
REPORT ENTITLED, "PHYSICIAN SERVICES: CONCIERGE CARE CHARACTERISTICS 
AND CONSIDERATIONS FOR MEDICARE" (GAO-05-776):

The Department of Health and Human Services (HHS) appreciates the 
opportunity to comment on the U.S. Government Accountability Office's 
(GAO) draft report.

General Comments:

The growth of concierge care has been the subject of some debate in the 
past few years. Much of the concern has focused upon the impact 
concierge care may have on beneficiary access to physician services. 
HHS agrees with the GAO's finding indicating that concierge care has 
had a minimal impact at this time. However, we remain interested in 
developments in concierge care. Therefore, we will continue to follow 
this area and to evaluate whether any further steps are indicated.

S. 345, 108TH Cong. 

[2] In Washington, for example, the Office of the Insurance 
Commissioner is monitoring concierge care and has considered requiring 
that physicians who charge a set fee in exchange for comprehensive 
primary care meet all the requirements that apply to health maintenance 
organizations. The basis for this requirement is that an agreement to 
provide unlimited health services in exchange for a fixed fee results 
in the assumption of insurance risk.

199, 118 Stat. 3, also directed GAO to study concierge care. H.R. Conf.

mandated our work used this term.

determined by a fee schedule and includes 80 percent payment from the 
program and 20 percent beneficiary coinsurance, once the beneficiary's 
annual deductible has been met.

[10] A beneficiary may be reimbursed no more than 80 percent of the fee 
schedule amount for nonparticipating physicians, regardless of how his 
or her nonparticipating physician chooses to bill. 

[11] This option became available through the Balanced Budget Act of 
1997, which amended the Social Security Act to specify that physicians 
may enter into private contracts with Medicare beneficiaries. Pub. L. 
No. 105-33, § 4507, 111 Stat. 251, 439 (codified at 42 U.S.C. §

[16] Other groups which have estimated the number of concierge 
physicians include the Society for Innovative Medical Practice Design 
(formerly the American Society of Concierge Physicians), which 
estimated that about 200 concierge physicians practice in the United 
States. AMA's Institute for Ethics located 144 concierge physicians, 
using the same identification approach that we followed, for its own 
study in 2003. 

[17] An MSA is a geographic region consisting of a central county or 
counties that contains an urban area with a population of at least 
50,000 plus any adjacent counties having a high degree of social and 
economic integration with the central county

[18] Two concierge physicians, both in Washington, were not located in 
MSAs. 

[19] Converting a conventional practice to a concierge practice may 
take time. Our data on new and established concierge practices included 
physicians responding to our survey who charged membership fees and 
offered enhanced features to at least some of their patients in October 
2004, although some of these physicians may have still been seeking 
additional concierge patients and continuing to treat some nonconcierge 
patients. 

[20] Because our survey included only physicians who practiced 
concierge care during October 2004, it does not account for physicians 
who may have started and discontinued concierge practices before that 
date, or physicians who started to practice concierge care after 
October 2004. 

[21] About one-third of our respondents were affiliated with a 
consulting firm that helps physicians establish and maintain concierge 
practices. This firm recommends that concierge physicians offer a 
program oriented toward preventive care, limit patients to no more than 
600 for each physician, and submit claims to insurers for covered 
services. 

[22] Our survey distinguished between concierge patients granted 
waivers of the membership fee but still offered the enhanced features 
of concierge care, and "nonconcierge" patients who were neither charged 
a membership fee nor offered the features associated with concierge 
care. 

[23] Information on the number of patients seen per day was provided by 
101 of the 103 physicians who reported that they established their 
concierge practices in the same community in which they had practiced 
before converting to concierge care. 

[24] Subspecialties for which concierge physicians reported seeing 
nonconcierge patients included pulmonary medicine, endocrinology, and 
nephrology. 

[25] HHS refers to concierge care contracts as "physician-patient 
retainer agreements."

[26] The memorandum also states that retainer agreements could be 
problematic if they attempt to substitute for Medicare supplemental 
insurance policies. CMS officials reported encountering problems with 
physicians offering unregulated supplemental policies in the mid-1990s. 
In June 2005, CMS officials told us that, while such substitutions are 
not allowed, they are no longer concerned that retainer arrangements 
are being used as substitutes for Medicare supplemental insurance.

and Human Services, Mar. 31, 2004). 

[28] 42 U.S.C § 1320a-7a(a)(2) (2000). 

[29] The term concierge patients includes all patients who are offered 
enhanced services or amenities, including those whose membership fees 
have been waived.

[33] It is possible that some beneficiaries have called Medicare claims 
contractors about concierge care and had their inquiries identified 
more generally, for example, as "miscellaneous."

[34] Fifteen contractors responded to our inquiry out of a total of 18 
contractors who process Medicare claims for outpatient physician 
services. 

[35] This contractor processes claims for physician services for 
California, Maine, Massachusetts, New Hampshire, and Vermont. 

[36] See app. I for a list of the organizations we contacted. 

[37] The scope of our work did not include physicians who imposed 
additional charges solely to cover the costs of routine administrative 
services, such as filling out forms. In addition, our results do not 
include the views of nonconcierge physicians or physicians who may have 
once practiced concierge care but no longer do.
