Why GAO Did This Study: 

MA organizations are entities that contract with the Centers for 
Medicare & Medicaid Services (CMS) to offer one or more private plans 
as an alternative to the Medicare fee-for-service (FFS) program. These 
MA plans are generally available to all Medicare beneficiaries, 
although certain types of plans, such as employer group plans, have 
specific eligibility requirements. Payments to MA organizations are 
based, in part, on the projected expenses and profits that MA 
organizations submit to CMS. These projections also affect (1) the 
extent to which MA beneficiaries receive additional benefits not 
provided under FFS and (2) beneficiary cost-sharing and premium 
amounts. The Patient Protection and Affordable Care Act (PPACA) 
required that, starting in 2014, MA organizations have a minimum 
medical loss ratio of 85 percent—that is, they must spend 85 percent 
of revenue on medical expenses, quality-improving activities, and 
reduced premiums. 

This report examines how MA organizations’ actual expenses and profits 
for 2011 as a percentage of revenue and in dollars compared to 
projections for the same year, both for plans available to all 
Medicare beneficiaries and for plans with specific eligibility 
requirements. GAO analyzed data on MA organizations’ projected and 
actual allocation of revenue to expenses and profits. The percentage 
of revenue spent on medical expenses reported in GAO’s study is not 
directly comparable to the PPACA medical loss ratio calculation, as 
the final rule defining the calculation was issued after actual 2011 
data were submitted. 

What GAO Found: 

Medicare Advantage (MA) organizations’ actual medical expenses, 
nonmedical expenses (such as marketing, sales, and administration) and 
profits as a percentage of total revenue were, on average, similar to 
projected values for plans available to all beneficiaries in 2011, the 
most recent year for which data were available at the time of the 
request for this work. MA organizations’ actual medical expenses, 
nonmedical expenses, and profits were 86.3 percent, 9.1 percent, and 
4.5 percent of total revenue, respectively. As a percentage of 
revenue, all three categories were within 0.3 percentage points of 
what MA organizations had projected. In addition, MA organizations 
received, on average, $9,893 in total revenue per beneficiary, 
slightly higher than the projected amount of $9,635. 

The percentage of revenue spent on medical expenses and profits varied 
between MA contracts. For example, while MA organizations spent an 
average of 86.3 percent of revenue on medical expenses, 39 percent of 
beneficiaries were covered under contracts where less than 85 percent 
of revenue was spent on medical expenses. In addition, the accuracy of 
MA organizations’ projections varied on the basis of the type of plans 
offered under the contract. For example, contracts for private fee-for-
service plans-—a plan type with new provider network requirements in 
2011—-had average profit margins that were 4 percentage points lower 
than projected. 

In 2011, plans offered by MA organizations with specific eligibility 
requirements had higher-than-projected profits. Special needs plans 
(SNP), which serve specific populations, such as those with specific 
chronic conditions, had an 8.6 percent profit margin, but had 
projected 6.2 percent. This higher percentage, combined with higher-
than-projected revenue, resulted in SNPs reporting an average profit 
per beneficiary of $1,115, or 44 percent higher than projected ($777). 
Employer group plans, which are offered by employers or unions to 
their employees or retirees, as well as to Medicare-eligible spouses 
and dependents of participants in such plans, had a 7.6 percent profit 
margin, but had projected 4.2 percent. The higher profit margin, 
combined with higher-than-projected revenue, resulted in employer 
plans receiving an average profit per beneficiary of $861, or 108 
percent higher than projected ($413). 

GAO requested comments from CMS, but none were provided.

The Honorable Sander M. Levin: 
Ranking Member: 
Committee on Ways and Means: 
House of Representatives: 

Dear Mr. Levin: 

In 2011, the federal government paid Medicare Advantage (MA) 
organizations--entities that offer a private health plan alternative 
to Medicare fee-for-service (FFS)--approximately $124 billion, or 
about 23 percent of all Medicare spending, to provide health care 
services to 12.1 million Medicare beneficiaries. The private health 
plans offered by MA organizations are generally available to all 
Medicare beneficiaries in the plans' service areas.[Footnote 1] 
However, certain types of plans, such as employer group plans--which 
are offered by employers or unions--and special needs plans (SNP)--
which serve specific populations--have more specific eligibility 
requirements.[Footnote 2] Payments to MA organizations are based in 
part on the projected medical expenses, nonmedical expenses (such as 
marketing, sales, and administration), and profits, which 
organizations submit in their bids for providing Medicare-covered 
services, and on actual enrollment and beneficiary health status. 
[Footnote 3] In addition to projections, MA organizations are required 
to report actual medical expenses, nonmedical expenses, and profits 
for the year 2 years prior to the upcoming year. For example, MA 
organizations reported their actual 2011 expenses in their bid 
submission for 2013. 

In June and December 2008, we reported on MA organizations' projected 
and actual medical expenses, nonmedical expenses, and profits for 2005 
and 2006, respectively.[Footnote 4] We reported that, on average, MA 
organizations' self-reported actual medical expenses as a percentage 
of revenue were lower in 2005 and 2006 than they had projected. 
Specifically, MA organizations projected that they would spend, on 
average, 90.2 percent of revenue on medical expenses in 2005 and 86.9 
percent in 2006. However, MA organizations' self-reported actual 
medical expenses were 85.7 percent of revenue, on average, in 2005, 
and 83.3 percent in 2006. The lower-than-projected expenses resulted 
in MA organizations receiving more profits, on average, than 
projected. Specifically, MA organizations earned profits of $1.1 
billion more than projected in 2005 and $1.3 billion more than 
projected in 2006. 

The accuracy of MA organizations' projections is important because, in 
addition to determining Medicare payments to these organizations, 
these projections affect the extent to which MA beneficiaries receive 
additional benefits not provided under FFS and the amounts 
beneficiaries pay in cost-sharing and premiums. Specifically, once 
Medicare payments are determined, they are not modified if there are 
differences between actual and projected expenses. Thus, if MA 
organizations had more accurately projected their revenue and expenses 
in 2005 and 2006, they would have, on average, been able to provide 
beneficiaries with additional benefits or cost-sharing reductions and 
still maintain the level of profits projected. 

The Patient Protection and Affordable Care Act (PPACA) included a new 
requirement that, starting in 2014, MA organizations' must have a 
minimum medical loss ratio of 85 percent--that is, they must spend at 
least 85 percent of their revenue on medical expenses, quality 
improving activities, and reduced premiums.[Footnote 5] If an MA 
organization spends less than 85 percent of its revenue on such 
expenses in a given year, it must refund payments to the Centers for 
Medicare & Medicaid Services (CMS) equal to 85 percent of its revenue 
less its actual expenses related to medical services, quality-
improving activities, and reduced premiums.[Footnote 6] If an MA 
organization fails to spend at least 85 percent of its revenue on 
medical expenses, quality-improving activities, and reduced premiums 
for more than 3 consecutive years, it will be subject to enrollment 
sanctions and, after 5 consecutive years, to contract termination. 

You asked us to provide baseline information on how MA organizations' 
self-reported actual expenses and profits compared to their 
projections prior to the effective date of the PPACA requirement for 
an 85 percent medical loss ratio. In this report, we examine how MA 
organizations' actual medical expenses, nonmedical expenses, and 
profits as a percentage of revenues and in dollars for 2011--the most 
recent year for which data were available at the time of your request--
compared to projections for the same year, both for plans available to 
all Medicare beneficiaries and for plans with specific eligibility 
requirements. 

To report actual 2011 medical expenses, nonmedical expenses, and 
profits, we analyzed 2013 bid data, which MA organizations submitted 
in 2012 and which include MA organizations' actual experience for 
2011.[Footnote 7] To report projected 2011 expenses and profits, we 
analyzed 2011 bid data, which MA organizations submitted to CMS in 
2010. Both the 2011 and 2013 bid data contain self-reported 
information on plan-level expenses and profits. We excluded Part D 
benefits from our analysis.[Footnote 8] We also excluded (1) plans 
that were not included in both an MA organization's 2011 and 2013 
bids, (2) regional preferred provider organizations (PPO),[Footnote 9] 
and (3) plans that had values equal to zero for per member per month 
(PMPM) total revenue, PMPM medical expenses, PMPM nonmedical expenses, 
or member months. To determine actual and projected expenses and 
profits for 2011, we multiplied both actual and projected PMPM 
expenses and profits by actual enrollment in member months for that 
year. 

We analyzed plans available to all Medicare beneficiaries at the 
contract level.[Footnote 10] Because employer group plans and SNPs 
have specific eligibility requirements and are not available to all 
Medicare beneficiaries, we analyzed such plans separately and excluded 
them from this part of our analysis. We also excluded contracts with 
fewer than 24,000 member months (equivalent to 2,000 beneficiaries 
enrolled for a full year), because CMS officials stated they do not 
consider data from these contracts to be fully credible. After all 
exclusions, our analysis included 322 contracts and 1,242 plans, which 
enrolled the equivalent of approximately 7.5 million beneficiaries--88 
percent of the total MA enrollment in plans available to all Medicare 
beneficiaries in 2011. We also determined whether differences in 
projected and actual expenses and profits for plans available to all 
Medicare beneficiaries varied on the basis of the type of plans under 
each contract or whether contracts had a high or low benchmark--the 
maximum amount Medicare will pay plans to serve an average beneficiary 
and which vary based on plans' service areas. We analyzed projected 
and actual expenses and profits for contracts that had the following 
plan types: health maintenance organizations (HMO), PPOs, and private 
fee-for-service (PFFS) plans.[Footnote 11] We calculated benchmarks at 
the contract level. Using county-level enrollment and benchmark data 
from CMS, we defined MA organizations' contracts as having a high 
benchmark if their enrollment-weighted average benchmark was above the 
enrollment-weighted average benchmark for all MA contracts in our 
analysis.[Footnote 12] We defined MA organizations' contracts as 
having a low benchmark if their enrollment-weighted average benchmark 
was equal to or below the enrollment-weighted average benchmark for 
all MA contracts in our analysis. 

We analyzed plans with specific eligibility requirements at the plan 
level, because SNPs and employer group plans can be included in 
contracts with plans available to all Medicare beneficiaries. We 
excluded SNPs and employer group plans with fewer than 24,000 member 
months. After all exclusions, our SNP analysis included 99 contracts 
and 121 plans, which enrolled the equivalent of approximately 1.0 
million beneficiaries--71 percent of the total SNP enrollment in 2011. 
After all exclusions, our employer group plan analysis included 77 
contracts and 111 plans, which enrolled the equivalent of 
approximately 1.7 million beneficiaries--77 percent of the total MA 
employer group enrollment in 2011.[Footnote 13] 

The results are reported for 2011 and may not be representative of or 
generalizable to other years.[Footnote 14] In addition, the percentage 
of total revenue spent on medical expenses reported in our study is 
not directly comparable to the PPACA medical loss ratio calculation. 
CMS issued its final rule defining the PPACA medical loss ratio 
calculation in 2013, which was after MA organizations submitted their 
bids for 2013 that contained MA organizations' actual 2011 expenses 
and profits.[Footnote 15] 

We took several steps to ensure that the data used to produce this 
report were sufficiently reliable. Specifically, we assessed the 
reliability of the CMS data we used by interviewing relevant 
officials, reviewing data documentation, and examining the data for 
obvious errors. We determined that the data were sufficiently reliable 
for the purposes of our study. 

We conducted this performance audit from August 2013 through December 
2013 in accordance with generally accepted government auditing 
standards. Those standards require that we plan and perform the audit 
to obtain sufficient, appropriate evidence to provide a reasonable 
basis for our findings and conclusions based on our audit objectives. 
We believe that the evidence obtained provides a reasonable basis for 
our findings and conclusions based on our audit objectives. 

Background: 

Payments to MA organizations are based on the MA organization's bid 
and benchmark and are adjusted for differences in projected and actual 
enrollment, beneficiary residence, and health status. PPACA changed 
how the benchmark and rebate are calculated. 

Payments to MA Organizations: 

Payments to MA organizations and the additional benefits that MA 
organizations offer are based in part on the relationship between the 
MA organizations' bids--their projection of the revenue required to 
provide beneficiaries with services that are covered under Medicare 
FFS--and a benchmark.[Footnote 16] If an MA organization's bid is 
higher than the benchmark, the organization must charge beneficiaries 
a premium to collect the amount by which the bid exceeds the 
benchmark. If an MA organization's bid is lower than the benchmark, 
the organization receives the amount of the bid plus additional 
payments, known as rebates, equal to a percentage of the difference 
between the benchmark and the bid. MA organizations are required to 
use rebates to provide additional benefits, such as dental or vision 
services; reduce cost-sharing; reduce premiums; or some combination of 
the three. 

CMS adjusts payments to MA organizations to account for differences in 
projected and actual enrollment, beneficiary residence, and health 
status. CMS adjusts for differences in projected and actual enrollment 
through its method for paying MA organizations. Specifically, MA 
organizations get paid a PMPM amount and thus only get paid for actual 
enrollees. CMS also adjusts PMPM payments to MA organizations on the 
basis of the ratio of the benchmark rate in the beneficiary's county 
to the plan benchmark. Thus, if a beneficiary comes from a county that 
has a benchmark rate that is lower than the plan's benchmark, the plan 
will receive a lower PMPM payment for that beneficiary. Finally, to 
help ensure that health plans have the same financial incentive to 
enroll and care for beneficiaries regardless of their health status, 
payments to MA organizations are adjusted for beneficiary health 
status--a process known as risk adjustment. Final payments are 
adjusted to account for differences between the projected average risk 
score--a relative measure of expected health care use for each 
beneficiary--submitted in plans' bids and the actual risk scores for 
enrolled beneficiaries. 

Bidding rules for employer health plans differ from those for MA plans 
available to all beneficiaries and SNPs. Specifically, MA 
organizations are able to negotiate specific benefit packages and cost-
sharing amounts with employers after the MA organizations submit their 
bid for an employer group plan. In contrast, MA organizations' bids 
for all other MA plans must reflect their actual benefit package--
including additional benefits, reduced cost-sharing, and reduced 
premiums--and MA organizations cannot change the benefits after the 
bid is approved by CMS. 

Changes under PPACA: 

PPACA changed how the benchmark is calculated beginning in 2011. These 
changes have resulted in a decrease, on average, in county benchmarks 
relative to average Medicare FFS expenditures. In 2011, benchmark 
rates were held constant at 2010 benchmark rates. From 2012 through 
2016, the benchmark will be a blend of the traditional benchmark 
formula and a new quartile-based formula. Counties will be stratified 
into quartiles based on their Medicare FFS expenditures, with the 
first quartile of counties (the 25 percent of counties that have the 
highest Medicare FFS expenditures) having a benchmark equal to 95 
percent of FFS expenditures. Counties in the second, third, and fourth 
quartiles will have benchmarks of 100 percent, 107.5 percent, and 115 
percent, respectively, of FFS expenditures. In addition, any MA 
organization that receives 3 or more stars on CMS's 5-star quality 
rating system will receive a bonus to the PPACA portion of their 
blended benchmark.[Footnote 17] In 2017 and future years, the quartile-
based formula will determine 100 percent of the benchmark value. 

PPACA also changed how the rebate is calculated. This change resulted 
in decreased rebate amounts starting in 2012. By 2014, the rebate 
amounts will be equal to 50, 65, or 70 percent of the difference 
between the benchmark and the bid, depending on the number of stars a 
plan receives on CMS's 5-star quality scale. Prior to 2012, MA 
organizations received a rebate equal to 75 percent of the difference 
between the benchmark and the bid. 

MA Plans with Specific Eligibility Requirements: 

SNPs and employer group plans have specific eligibility requirements. 
SNPs serve specific populations, including beneficiaries who are 
dually eligible for Medicare and Medicaid, are institutionalized, or 
have certain chronic conditions. Employer group plans are MA plans 
offered by employers or unions to their Medicare-eligible retirees and 
Medicare-eligible active employees, as well as to Medicare-eligible 
spouses and dependents of participants in such a plan. In those cases 
where an active employee is enrolled in an employer's non-Medicare 
health plan, the Medicare employer group plan would serve as a 
secondary payer, while the employer's non-MA plan for active employees 
would serve as the primary payer. 

2011 Expenses and Profits Were Similar to Projections for Plans 
Available to All Beneficiaries, but Plans with Specific Eligibility 
Requirements Had Higher-than-Projected Profits: 

Among plans available to all beneficiaries, 2011 expenses and profits 
represented similar percentages of total revenue compared to 
projections. Among plans with specific eligibility requirements--that 
is, SNPs and employer group plans--2011 expenses were lower and 
profits were higher as a percentage of revenue compared to projections. 

For Plans Available to All Beneficiaries in 2011, Expenses and Profits 
Represented Similar Percentages of Total Revenue Compared to 
Projections: 

As a percentage of 2011 total revenue, MA organizations' actual 
medical expenses, nonmedical expenses, and profits were, on average, 
similar to projected values for plans available to all beneficiaries. 
[Footnote 18] As a percentage of revenue, medical expenses and profits 
were slightly lower than projected, while nonmedical expenses were 
slightly higher. Also, as a percentage of revenue, all three 
categories were within 0.3 percentage points of what MA organizations 
had projected (see table 1).

Notes: Table includes data from 322 contracts and 1,242 plans, which 
enrolled the equivalent of approximately 7.5 million beneficiaries--88 
percent of the total MA enrollment in plans available to all Medicare 
beneficiaries in 2011. To determine actual and projected expenses and 
profits for 2011, we multiplied both actual and projected per member 
per month expenses and profits by actual enrollment in member months 
for that year. Data on actual and projected expenses and profits were 
self-reported by MA organizations. Percentages may not add to 100 and 
medical expenses, nonmedical expenses, and profits may not equal total 
revenue because of rounding. 

[End of table] 

MA plans that were available to all beneficiaries received slightly 
higher total revenue per beneficiary than projected, which could be a 
result of differences between actual and projected health status and 
geographic location of beneficiaries who enrolled. For instance, MA 
plans could have received additional Medicare payments if they 
enrolled beneficiaries who were expected to need more health care, who 
were disproportionately from counties with higher benchmarks, or a 
combination of these two reasons. Because of the higher total revenue, 
medical expenses as a percentage of revenue were 0.2 percentage points 
lower than projected, despite MA organizations' spending more dollars 
on medical expenses than projected. 

The percentage of revenue spent on medical expenses and profits varied 
substantially between MA contracts. For example, while MA 
organizations spent an average of 86.3 percent of revenue on medical 
expenses, approximately 39 percent of beneficiaries were covered by 
contracts where less than 85 percent of revenue was spent on medical 
expenses, and 13 percent of beneficiaries were covered by contracts 
where less than 80 percent of revenue was spent on medical expenses 
(see table 2). Further, while the average profit margin was 4.5 
percent among plans available to all beneficiaries, 26 percent of 
beneficiaries in our analysis were covered by contracts where profit 
margins were negative. In contrast, 15 percent of beneficiaries in our 
analysis were covered by contracts where profit margins were 10 
percent or higher.[Footnote 19]

of total revenue spent on medical expenses and profits by actual 2011 
enrollment.

For MA organizations with either high or low benchmarks, profit 
margins and the percentage of total revenue devoted to expenses were, 
on average, similar to projections. As a percentage of revenue, MA 
organizations with high benchmarks had slightly lower-than-projected 
medical expenses but slightly higher-than-projected nonmedical 
expenses and profits (see table 3). As a percentage of revenue, MA 
organizations with low benchmarks had slightly higher-than-projected 
medical expenses and nonmedical expenses but slightly lower profits. 
In addition, MA organizations with high benchmarks had higher profit 
margins compared to those with low benchmarks. Specifically, 
organizations with high benchmarks had an average profit margin of 5.9 
percent and made $668 per beneficiary compared to 3.5 percent and $313 
per beneficiary for organizations with low benchmarks.

Notes: Table includes data from 322 contracts and 1,242 plans, which 
enrolled the equivalent of approximately 7.5 million beneficiaries--88 
percent of the total MA enrollment in plans available to all Medicare 
beneficiaries in 2011. To determine actual and projected expenses and 
profits for 2011, we multiplied both actual and projected per member 
per month expenses and profits by actual enrollment in member months 
for that year. Data on actual and projected expenses and profits were 
self-reported by MA organizations. Percentages may not add to 100 and 
medical expenses, nonmedical expenses, and profits may not equal total 
revenue because of rounding. 

[End of table] 

The accuracy of MA organizations' projections varied on the basis of 
the type of plan they offered under each contract. Among the three 
plan types studied (HMO, PPO, and PFFS), PFFS contracts had the 
largest differences, in percentage point terms, between their actual 
and projected expenses and profits. For example, as a result of 
spending, on average, a higher-than-projected percentage of total 
revenue on medical and nonmedical expenses, PFFS contracts reported an 
actual profit margin of only 0.3 percent after projecting a 4.3 
percent profit margin (see table 4). HMO contracts had the highest 
profit margins and were the only type of contract, among the three 
studied, that averaged higher profits than projected. Specifically, 
HMO contracts had a 5.3 percent profit margin, which was slightly 
higher than projected--5.0 percent--and substantially higher than the 
profit margins of PPO and PPFS contracts--2.5 percent and 0.3 percent, 
respectively.

[End of table] 

For Plans with Specific Eligibility Requirements in 2011, Expenses 
Were Lower and Profits Were Higher as a Percentage of Total Revenue 
Compared to Projections: 

SNPs' profits were higher than projected both in terms of a percentage 
of total revenue and in dollars. SNPs received somewhat higher revenue 
than projected and spent a lower percentage of total revenue on 
medical and nonmedical expenses than projected (see table 5). As a 
result of the higher-than-projected revenue and spending a lower 
percentage of revenue on expenses, SNPs reported an average profit per 
beneficiary of $1,115, which was 44 percent higher than projected 
($777) and 149 percent higher than the profit per beneficiary for 
plans available to all Medicare beneficiaries ($447).[Footnote 20] 
Compared to plans available to all Medicare beneficiaries, SNPs spent 
more in terms of amount per beneficiary, but less in percentage terms, 
on medical and nonmedical expenses. CMS officials said SNPs might have 
higher profit margins because of the potential additional risk of 
providing a plan that targets a specific population. For instance, the 
officials noted that it may be more difficult to predict revenue and 
spending for a SNP's targeted population. SNPs may face higher medical 
expenses because beneficiaries enrolled in such plans may have 
increased health care needs. According to CMS officials, SNPs may also 
face higher administrative expenses for several reasons, such as 
potentially higher marketing expenses associated with targeting SNPs' 
designated population.

Notes: Table includes data from 99 contracts and 121 plans, which 
enrolled the equivalent of approximately 1.0 million beneficiaries--71 
percent of the total SNP enrollment in 2011. To eliminate the effects 
caused by any differences between actual and projected enrollment, we 
used actual enrollment to calculate both projected and actual expenses 
and profits. Data on actual and projected expenses and profits were 
self-reported by MA organizations. Medical expenses, nonmedical 
expenses, and profits may not equal total revenue because of rounding. 

[End of table] 

Employer group plans had higher revenue, had higher profit margins, 
and spent a lower percentage of total revenue on expenses than 
projected. Specifically, total revenue per beneficiary was about 14 
percent higher than projected--$11,364 compared to $9,957 (see table 
6). In addition, employer group plans spent 86.3 and 6.1 percent of 
total revenue on medical expenses and nonmedical expenses, 
respectively, compared to a projected 89.5 and 6.3 percent, and these 
plans also had an actual profit margin of 7.6 percent compared to a 
4.2 percent projected profit margin. The combined effects of higher 
revenue and a higher profit margin translated into average profits per 
beneficiary of $861, which was 108 percent higher than projected 
($413) and 93 percent higher than the profit per beneficiary for plans 
available to all Medicare beneficiaries ($447).[Footnote 21] Unlike 
other MA plans, projections for employer group plans may vary from 
their actual profits and expenses because MA organizations that offer 
such plans are able to negotiate specific benefit packages and cost-
sharing amounts with employers after they submit their bids to CMS.

Footnotes: 

[1] Medicare beneficiaries with end-stage renal disease (ESRD) can 
only enroll in an MA plan if they meet certain criteria. For example, 
beneficiaries with ESRD may enroll in an MA plan if (1) they were 
already enrolled in the MA plan when they developed ESRD; (2) they are 
eligible for a plan offered by their current or former employer or 
union that has opted to enroll beneficiaries with ESRD; or (3) they 
had a successful kidney transplant. 

[2] Employer group plans can be offered to employers' or unions' 
Medicare-eligible retirees and Medicare-eligible active employees, as 
well as to Medicare-eligible spouses and dependents of participants in 
such plans. For active employees, the employer group plan would serve 
as a secondary payer, while the employer's non-MA plan for active 
employees would serve as the primary payer. SNPs offer benefit 
packages tailored to beneficiaries who are dually eligible for 
Medicare and Medicaid, are institutionalized, or have certain chronic 
conditions. 

[3] Profits refer to plans' remaining revenue after medical expenses 
and nonmedical expenses are paid. In certain circumstances, such as 
for new market entrants, the Centers for Medicare & Medicaid Services 
(CMS) allows a plan to have a negative profit, meaning that the plan's 
revenue is less than its combined medical and nonmedical expenses.

made by the Health Care and Education Reconciliation Act of 2010. 
Health Care and Education Reconciliation Act of 2010, Pub. L. No. 111-
152, § 1103, 124 Stat. 1029, 1047 (2010) (adding section 1857(e)(4) of 
the Social Security Act). CMS regulations set forth specific 
requirements for calculating the PPACA medical loss ratio. Medicare 
Program; Medical Loss Ratio Requirements for the Medicare Advantage 
and the Medicare Prescription Drug Benefit Programs, 78 Fed. Reg. 
31284 (May 23, 2013) (to be codified at 42 CFR Part 422). PPACA 
similarly requires non-Medicare private health plans to spend a 
minimum percentage of the plans' revenue on medical expenses and 
quality-improving activities. Effective January 1, 2011, plans that do 
not meet these requirements must provide a partial refund to those 
individuals enrolled in the plan. Pub. L. No. 111-148, §§ 1001(5), 
10101(f), 124 Stat. 119, 130, 885 (2010) (inserting and amending a new 
section 2718 in the Public Health Service Act). For information on the 
early experiences associated with implementing these requirements, see

[6] CMS is the agency that administers the Medicare program. 

[7] To secure the award of an MA contract, MA organizations must 
submit bids to CMS for each plan they intend to offer under the 
contract. In some cases, plans available in 2011 were consolidated 
with other plans by 2013 or the plans were closed and the enrollees 
were expected to primarily be enrolled in other plans offered by the 
MA organizations in 2013. In either of these situations, MA 
organizations may have reported data in their 2013 bids that reflected 
the combined actual expenses and profits for more than one plan. The 
bid data were not structured in a way that allowed us to disaggregate 
the expenses and profits by plan in these cases. As a result, we 
assigned the expenses and profits reported on the bid to the plan that 
submitted the bid. 

[8] Medicare Part D provides coverage for outpatient prescription 
drugs to beneficiaries purchasing such coverage. MA plans may provide 
coverage for Medicare Part D benefits and bid separately to offer this 
coverage. 

[9] Beneficiaries in PPOs can see both in-network and out-of-network 
providers but pay higher cost-sharing amounts if they use out-of-
network services. Regional PPOs serve state or multistate regions 
established by CMS. We excluded regional PPOs from our analysis 
because of differences in the way such plans are paid by Medicare. 

[10] MA organizations contract with CMS to provide health benefits to 
Medicare beneficiaries. Under each contract, MA organizations can 
offer multiple health plans from which beneficiaries choose. 

[11] While each contract may include more than one plan, each contract 
is designated as having only one plan type. Beneficiaries in HMOs are 
generally restricted to seeing providers within a network. 
Beneficiaries enrolled in PFFS plans may generally see any provider 
that accepts the plan's payment terms; however, since 2011, these 
plans have been generally required to maintain a network of contracted 
providers, and beneficiaries that see out-of-network providers may pay 
higher cost-sharing amounts. 

[12] We used CMS's publicly available county-level MA enrollment data 
to calculate benchmark weights. These data do not include enrollment 
counts for counties in which a plan has 10 or fewer enrollees. Because 
of this exclusion, the population we used to calculate benchmark 
weights represented approximately 97 percent of the total MA 
population. 

[13] Our total study population included approximately 10.1 million 
beneficiaries--83 percent of the total MA enrollment in 2011, when 
combining the three populations studied (MA beneficiaries enrolled in 
plans available to all Medicare beneficiaries, SNPs, and employer 
group plans). 

[14] Because of differences in our methodologies, the results 
presented in this report are not directly comparable to our past 
reports on this topic. For instance, we analyzed SNPs separately in 
this report, whereas SNPs were not separated out in our previous 
reports because such data were not available. 

[15] For example, CMS's 2013 final rule defined quality-improving 
activities that could be included in the PPACA medical loss ratio 
calculation. While MA organizations' 2013 bids included information on 
quality-improving activity expenditures, CMS officials had told MA 
organizations that the information was being collected for 
informational purposes only and told us that MA organizations' 
methodologies used to calculate quality-improving activities and the 
accuracy of the information provided was unclear. See Medicare 
Program; Medical Loss Ratio Requirements for the Medicare Advantage 
and the Medicare Prescription Drug Benefit Programs; Final Rule, 78 
Fed. Reg. 31,284 (May 23, 2013). 

[16] Benchmarks are based on county-level payment rates used to pay MA 
plans before 2006. From 2007 through 2010, benchmarks were generally 
updated annually by the overall growth in Medicare expenditures. PPACA 
changed how benchmarks were calculated beginning in 2011, principally 
by more closely aligning the benchmark with Medicare FFS spending. 
Benchmarks are calculated differently for regional PPOs. Specifically, 
benchmarks for regional PPOs are updated by combining the county 
benchmarks in each region with a weighted average of regional plan 
bids. 

[17] In 2008, CMS implemented a 5-star quality rating system--with 5 
stars indicating the highest quality--for MA plans as a tool to help 
beneficiaries make enrollment decisions. Stars are assigned at the 
contract level, with every plan covered under the same contract 
receiving the same star rating. Plans' overall star ratings indicate 
their performance relative to that of all other plans on about 50 
measures of clinical quality, patient experience, and contract 
performance. 

[18] Throughout this report, we examined aggregate expenses and 
profits by weighting the average per member per month profits and 
expenses for individual plans and contracts by actual enrollment. 

[19] All contracts with profit margins of 10 percent or higher spent 
less than 85 percent of their total revenues on medical expenses. 
Among these contracts, the median percentage spent on medical expenses 
was approximately 77 percent. Throughout the report, we calculate 
profit margins by dividing profits by total revenue. 

[20] Compared to plans available to all beneficiaries, SNPs had a 
higher median profit margin. In addition, SNPs' average profit margin 
was higher than that of plans available to all beneficiaries after 
accounting for plan type (i.e., HMO or PPO), whether the plans had 
high or low benchmarks, and after excluding plans located in Puerto 
Rico, where the MA market has some unusual characteristics, such as 
having benchmarks that are substantially higher relative to Medicare 
FFS than other areas of the United States. Further, all three types of 
SNPs--dual-eligible, chronic condition, and institutional SNPs--had 
profit margins of at least 8.4 percent. Because our exclusion criteria 
resulted in our excluding a higher percentage of chronic care and 
institutional SNPs than dual-eligible SNPs, our SNP population was 
disproportionately composed of dual-eligible SNPs, and the population 
of chronic care and institutional SNPs studied was relatively small. 
For instance, 92 percent of the beneficiaries enrolled in the SNPs we 
studied were enrolled in dual-eligible SNPs, whereas approximately 81 
percent of the total SNP population was enrolled in dual-eligible SNPs 
in 2011. 

[21] Compared to plans available to all beneficiaries, employer group 
plans had a higher median profit margin. In addition, employer plans 
received higher total revenues per beneficiary and had a higher 
average profit margin than plans available to all beneficiaries after 
accounting for plan type (i.e., HMO or PPO) and whether the plans had 
high or low benchmarks.
