Congressional Committees: 

In response to rapidly rising home health spending from the late 1980s 
through the mid-1990s, the Congress enacted major changes to 
Medicare's home health payments in the Balanced Budget Act of 1997 
(BBA).[Footnote 1] These and subsequent changes culminated in the 
implementation of a prospective payment system (PPS) on October 1, 
2000, which provides incentives to home health agencies (HHAs) to 
operate efficiently. Under the PPS, HHAs are paid a fixed amount, 
adjusted for a beneficiary's care needs, for providing up to 60 days 
of care, termed a home health episode. The BBA also created an interim 
payment system (IPS) that imposed new payment limits to moderate 
spending until the PPS could be implemented. The PPS was designed to 
lower Medicare spending below what it was under the IPS. This spending 
reduction was to be achieved by setting the PPS episode payment amount 
so that total home health spending under the PPS in fiscal year 2000 
would equal what would have been spent had the interim limits been 
reduced by 15 percent. Subsequent legislation delayed implementation 
of the mandated reduction to the episode payment amount until October 
2002.[Footnote 2] The Centers for Medicare and Medicaid Services 
(CMS)[Footnote 3] has determined that the fiscal year 2003 episode 
payment rate would have to be reduced by about 7 percent to achieve 
the mandated level of savings.[Footnote 4] 

To help decide whether to implement, modify, or eliminate the reduction
to Medicare home health payments, the Congress directed us to evaluate 
payments under the PPS.[Footnote 5] To do this, we estimated average 
home health episode costs and calculated average episode payments for 
the first 6 months of 2001. We also interviewed industry 
representatives and officials from CMS and reviewed regulations and 
studies of the home health PPS. We performed our work from November 
2001 through April 2002 in accordance with generally accepted 
government auditing standards. (For a discussion of our scope and 
methodology, see appendix I.) 

Results in Brief: 

Medicare's payments for full home health care episodes were, on 
average, about 35 percent higher than the estimated costs of home 
health care provided in the first 6 months of 2001. This disparity 
results from an episode payment amount that was initially set assuming 
a higher number of visits than was being provided prior to the PPS. 
After the PPS was implemented, HHAs further reduced the number of 
visits provided per episode, which lowered their costs. At the same 
time, a higher proportion of beneficiaries receiving home health care 
was categorized into the more intensive payment groups, which 
generated higher payments.[Footnote 6] Across the Medicare PPS payment 
groups, there was considerable variation in the relationship between 
payments and estimated costs. Payments were above estimated costs for 
75 of the 80 payment groups. For five of the payment groups, payments 
were slightly below or about equal to estimated costs. These payment 
and cost disparities indicate that Medicare's PPS, which was designed 
to ensure adequate payments for HHAs that operate efficiently, 
overpays many HHAs for the services that were actually provided, 
although some HHAs that face extraordinary costs not accounted for by 
the payment groups may be financially disadvantaged. 

Because Medicare payments for home health care far exceed associated 
estimated costs, the Congress should consider allowing the mandated 
reduction to payments to be implemented. However, as we have stated 
before, we believe that the incentives of the episode-based PPS need 
to be moderated to protect beneficiaries from underservice, the 
Medicare program from overpaying for services, and HHAs from potential 
underpayments.[Footnote 7] Therefore, we continue to believe that the 
PPS should incorporate risk sharing of financial gains and losses 
between the Medicare program and HHAs. 

In written comments on a draft of this report, CMS stated that our 
findings are consistent with its preliminary analysis of data from the 
first year of the PPS, but that HHA costs cannot be known with 
certainty until Medicare cost reports are available. CMS expressed 
concern about implementing risk sharing as part of the home health 
PPS, stating that risk sharing is inconsistent with providing timely 
and predictable payments under the PPS, is administratively difficult, 
and is not necessary because our concerns about possible overpayments 
or underpayments to HHAs can be addressed in other ways. Concerning 
CMS' first point, our episode cost estimates are based on the actual 
number and mix of visits provided to Medicare beneficiaries during the 
first 6 months of 2001 and the per-visit cost estimates used by the 
Heath Care Financing Administration (HCFA) to set the initial episode 
payments, updated for inflation and adjusted for the change in average 
visit time. We note that CMS has experience in administering payment 
adjustments similar to risk sharing that rely on actual provider 
experience while ensuring that payments are timely and predictable. 
Furthermore, monitoring activities to detect overpayments or 
underpayments have not yet been implemented. In oral comments on a 
draft of this report, representatives from three home health care 
associations stated that they disagreed with our conclusions and 
believe that a reduction in Medicare's payments will harm the 
industry. However, the magnitude of the disparity between payments and 
estimated costs demonstrates that the reduction would not harm the 
industry. Risk sharing would provide protection to those HHAs that may 
incur costs that are higher than these estimates. 

Background: 

Medicare's home health benefit enables certain beneficiaries with post-
acute-care needs (such as recovery from joint replacement) and chronic 
conditions (such as congestive heart failure) to receive care in their 
homes. To qualify for home health care, beneficiaries must be confined 
to their residence ("homebound");[Footnote 8] require part-time or 
intermittent skilled nursing, physical therapy, or speech therapy; be 
under the care of a physician; and have the services furnished under a 
plan of care prescribed and periodically reviewed by a physician. If 
these conditions are met, Medicare will pay for the following types of 
visits: skilled nursing; physical, occupational, and speech therapy; 
medical social service; and home health aide. As long as beneficiaries 
continue to remain eligible for home health services, they may receive 
an unlimited number of visits. Beneficiaries are not liable for any 
out-of-pocket costs for this benefit. 

Pre-BBA Spending and Service Use: 

Medicare home health payments grew at an average annual rate of 25 
percent between 1990 and 1997, more than three times the rate of 
spending growth for the entire Medicare program. The growth in 
spending was attributable primarily to increases in the number of 
visits provided and not in the payment per visit. The number of 
Medicare beneficiaries receiving home health almost doubled during 
that period, from 57 to 109 beneficiaries per 1,000. At the same time, 
the average number of visits provided per home health user grew from 
36 to 73 visits. The rapid growth in home health use was due, in part, 
to the cost-based payment method. Under the cost-based system, BTUs 
were paid their costs up to a per-visit limit for each visit 
provided.[Footnote 9] This method, at a time when there was little 
program oversight, offered few incentives to provide visits 
efficiently or only when needed. 

By 1997, home health utilization—as measured by the number of home 
health users per 1,000 Medicare beneficiaries and the number of visits 
provided—varied widely across geographic regions. For example, 48 
Medicare beneficiaries per 1,000 in Hawaii received home health care 
in 1997. In the same year, more than 157 beneficiaries per 1,000 
received home health care in Louisiana. Meanwhile, Medicare home 
health users in Washington received an average of 32 visits, compared 
to an average of 161 visits per user in Louisiana. This wide variation 
in use persisted even after controlling for patient diagnosis. This 
variability is partly due to the lack of standards for necessary or 
appropriate care. Furthermore, even the most basic unit of service—the 
visit—was not well defined in terms of either the amount of time spent 
with a patient or the type of services provided. 

BBA Changes to Home Health Payment Policies: 

To constrain Medicare home health spending growth, BBA required HCFA 
to replace Medicare's cost-based, per-visit payment method with a PPS 
by fiscal year 2000.[Footnote 10] Until PPS could be implemented, BBA 
imposed spending controls under the IPS: For 3 years beginning October 
1, 1997, the IPS incorporated tighter per-visit cost limits than had 
previously been in place and subjected each HHA to an annual Medicare 
revenue cap, which was the product of an HHA-specific, per-beneficiary 
amount and the number of beneficiaries that the HHA served.[Footnote 
11] 

Under the PPS, an HHA receives a single payment for all items and 
services furnished during each 60-day episode of care.[Footnote 12] 
The payment rate is based on the national average cost of providing 
care in 1997, not an HHA's actual costs. Because the payment is 
divorced from an HHA's cost of delivering care, an HHA that delivers 
care for less than the payment amount can profit; conversely, an HHA 
will lose financially if its service costs are higher than the 
payment. To account for differences in beneficiary care needs, PPS 
episode payments are adjusted from a base rate (which was $2,115 in 
fiscal year 2001). These adjustments are based on a classification 
system that groups home health beneficiaries into 80 payment groups. 
The payment for a beneficiary in the most intensive payment group is 
approximately five times greater than the payment for a beneficiary in 
the least intensive group. In fiscal year 2001, episode payments 
ranged from $1,114 to $5,947. 

Financial Incentives of Episode-Based Payments: 

We have reported the strong financial incentives under the home health 
PPS to reduce the costs of providing an episode of care.[Footnote 13] 
HHAs can do this by reducing unnecessary or excessive visits, 
delivering care more efficiently, or underserving beneficiaries. We 
expressed concern that it may be hard to detect when the latter 
occurs. The lack of standards for necessary or appropriate care makes 
it difficult to review care and take steps to ensure that needed 
services are being delivered. We also said that the PPS could lead to 
substantial overpayments to some HHAs relative to the level of 
services being provided. Further, we noted industry concerns about the 
ability of some HHAs to respond to PPS incentives to reduce their 
costs and about inadequacies in the method used to adjust payments to 
account for differences in beneficiary care needs.[Footnote 14] 

As a result of these concerns, we recommended that risk sharing be 
incorporated into the PPS design.[Footnote 15] Risk sharing would 
limit the total losses and gains an HHA could experience over a period 
of time for treating beneficiaries by establishing formulas to share 
losses or gains with the Medicare program. This would involve a 
settlement process in which an HHA's actual costs of delivering care 
over the relevant period would be compared to its actual payments. 
Such an approach would simultaneously protect beneficiaries against 
underservice, the Medicare program from overpaying for services, and 
HHAs serving beneficiaries with greater than average needs when the 
costs are not accounted for in the payment adjustments. HCFA did not 
agree with our recommendation, stating that the PPS design and payment 
adjustments would address our concerns and that risk sharing would be 
difficult to implement. We subsequently suggested that the Congress 
consider requiring HCFA to implement risk sharing with the PPS. 
[Footnote 16] 

Home Health PPS Episode Payments Are Considerably Higher than 
Estimated Costs of Care Provided: 

The average episode payment HHAs received to provide an episode of 
care in the first 6 months of 2001 was about 35 percent higher than 
the average estimated cost of providing that care.[Footnote 17] The 
average episode payment, accounting for the mix of beneficiaries 
treated in the first 6 months of 2001, was $2,691. (See table 1.) 
During this period, we estimated that the cost of providing an episode 
of care was $1,997 after adjusting for the mix of services provided by 
agencies and changes in the average time spent for each type of visit 
since the introduction of the PPS. 

This large difference between the average episode payment and 
estimated cost is due to three factors. First, the PPS episode payment 
amount was calculated on the assumption that about 32 visits would be 
provided during an average episode, although immediately prior to PPS 
implementation only about 29 visits per episode were provided. Second, 
HHAs have further lowered their costs since PPS by providing, on 
average, only about 22 visits per episode during the first half of 
2001. Third, HHA payments have increased because a larger proportion 
of home health users have been categorized into higher payment groups. 

While the PPS adjusts payment rates to account for expected variation 
in costs due to patient care needs, the relationship between average 
payments and average estimated costs masks wider differences between 
payments and estimated costs across the 80 home health payment groups. 
The relationship between payments and estimated costs for the 10 
payment groups that account for almost half of home health episodes 
ranged from 72 percent above the estimated cost to 4 percent below in 
the first 6 months of 2001. (See table 2.) For the five payment groups 
with the lowest payments relative to estimated costs, which accounted 
for 8 percent of all episodes, the payment ranged from about 9 percent 
below to about equal the average estimated cost of services provided. 
The payment was greater than the average estimated cost for the 
remaining groups. 

For any HHA, the relationship between Medicare payments and the costs 
of providing care will likely vary from the averages we report here. 
The 

PPS was designed to provide adequate payments to BTUs that operate 
efficiently and to provide incentives for BTUs to become more 
efficient. But certain BTUs may have costs higher than payments if 
they face extraordinary costs not accounted for by the PPS payment 
groups.

Conclusions: 

The Medicare program is paying HHAs on average considerably more than 
the estimated cost of care beneficiaries are receiving. Consequently, 
implementation of the BBA-mandated 15 percent payment reduction, which 
would lower fiscal year 2003 PPS payments by 7 percent, should not 
affect HHAs' ability to serve Medicare beneficiaries. This payment 
reduction would move the Medicare program closer to becoming a prudent 
purchaser of home health care, but the reduction by itself is not 
sufficient. A single payment to cover all services provided during a 
60-day episode of care, combined with the lack of standards for what 
constitutes necessary or appropriate home health care, leaves 
beneficiaries vulnerable to underservice, Medicare vulnerable to 
future overpayments, and HHAs with a disproportionate number of 
beneficiaries with extensive needs vulnerable to underpayments. 
Implementing the 15 percent reduction would not lessen these 
vulnerabilities. This is why we have previously recommended that the 
PPS include risk sharing to simultaneously protect beneficiaries, the 
Medicare program, and HHAs. 

Matters for Congressional Consideration: 

The Congress should consider making no change in the requirement for a 
reduction in Medicare home health payments. We continue to urge the 
Congress to require CMS to incorporate risk sharing into the PPS 
design. 

Agency Comments and Our Evaluation: 

In written comments on a draft of this report, CMS stated that our 
findings are consistent with its preliminary analysis of data for the 
first year of the PPS. It noted that cost report data, which are not 
yet available for the first year of the PPS, would be required to 
determine the costs of home health services under the PPS with 
certainty. CMS reiterated its concerns about implementing risk sharing 
as a part of the PPS. It believes that risk sharing would undermine 
the main benefit of PPS, which is payments that are timely and 
predictable. Further, CMS stated its belief that the outlier payment 
policy under the home health PPS and planned monitoring activities 
should mitigate our concern that some HHAs may be vulnerable to 
underpayments. Finally, CMS stated that risk sharing is 
administratively difficult. 

Although cost report data would more accurately reflect an HHA's 
costs, our episode cost estimates build on historic visit costs, 
adjusted for inflation and changes in visit time, and reflect actual 
service use, a major determinate of episode costs. We believe that the 
new evidence we present on the wide disparity between payments and 
estimated costs on average and across payment groups demonstrates the 
need for and the value of risk sharing in conjunction with the home 
health PPS. Risk sharing would not remove the incentives under the PPS 
for HHAs to provide care efficiently, because they would continue to 
benefit financially when their costs are below their payments and lose 
financially when their costs are above their payments. Yet, risk 
sharing would mitigate extreme gains and losses under the PPS. While 
the monitoring activities and refinements that CMS discusses such as 
revisions to the payment groups could mitigate extreme gains or 
losses, it could be some time until they are implemented. Furthermore, 
outlier payments, which account for less than 3 percent of payments, 
are not by themselves sufficient to protect vulnerable HHAs that have 
higher than average costs across a number of patients, nor do they 
protect the Medicare program from excessive spending. 

We believe that CMS could overcome any administrative difficulties in 
implementing risk sharing. CMS incorporated a risk-sharing arrangement 
in its demonstration project on the home health PPS while ensuring 
predictable and timely payments. We note that CMS has considerable 
experience in adjusting prospective payments to providers based on 
expectations for a provider's costs in the coming year, most recently 
in implementing the hospital outpatient PPS, which has a provision to 
protect hospitals from losses. 

CMS' comments are included as appendix II. 

We received oral comments on a draft of this report from 
representatives of three home health care associations—American 
Association for Homecare (AAHomecare), National Association for Home 
Care (NAHC), and Visiting Nurse Associations of America (VNAA). These 
organizations disagreed with our conclusions. All three associations 
expressed concern about the effect of a potential payment reduction on 
the industry's stability and, in particular, its ability to care for 
medically complex patients. The associations said it was too early in 
the experience of the PPS to accurately measure home health care use, 
visit costs, episode costs, or industry profit margins. VNAA stated 
that our cost estimates do not reflect current fixed costs under the 
PPS. NAHC raised questions about the timeliness of payments if risk 
sharing is a part of the home health PPS. The associations said that 
more information was needed on how low-utilization episodes, partial 
episodes, and outlier payments would affect the relationship between 
average episode costs and payments to HHAs. 

Our results are consistent with CMS' analysis of a full year of 
experience under the PPS. Our analysis of 1.48 million episodes did 
not consider the payment reduction for partial episodes, payment 
enhancement for outliers, or variable payment adjustments for a 
significant change in a beneficiary's condition. When calculating 
episode payments and estimated costs we treated these as full 
episodes. The impact of these payment adjustments on average episode 
payments is likely to be minimal because they are partially offsetting 
and apply to less than 8 percent of episodes. Whether the visit costs 
for these types of episodes is different from the average visit costs 
is not known. We excluded low-utilization episodes from our analysis 
because they are not paid an episode rate. HHA visits per user have 
been dropping since 1997, allowing ample time for HHAs to bring their 
fixed costs in line with current use patterns. The magnitude of the 
difference between payments and estimated costs provides compelling 
evidence that the legislated reduction would not destabilize the home 
health industry. Further, risk sharing if implemented would moderate 
any negative effects on the HHAs that may incur costs that are higher 
than these estimates including when HHAs treat medically complex 
patients. 

We are sending copies of this report to the Administrator of CMS. We 
will also make copies available to others upon request.

Appendix I: Scope and Methodology: 

We conducted our analyses using Medicare provider, claims, and 
beneficiary files for calendar years 2000 and 2001. We included only 
those providers that were listed as active in each year. For episodes 
ending on January 1, 2001 through June 30, 2001, we used all final 
bills from the home health Standard Analytic File (SAF) for 2001 that 
were available as of January 24, 2002. Our file of 1.48 million 
episodes, which excludes all low-utilization episodes, does not 
include any claims for the first 6 months of 2001 submitted after 
January 24, 2002. For 2000, we used all final bills ending on January 
1, 2000 through June 30, 2000. 

To compute our estimate of average episode costs, we used HCFA's per-
visit cost estimates that were used to establish the PPS episode rates 
and that were calculated from the sample of fiscal year 1997 audited 
costs reports.[Footnote 18] The per-visit costs, which include all 
costs of home health services covered and paid for on a reasonable 
cost basis, were inflated to 2001 cost levels using the market basket 
index for home health services. Then we adjusted the per-visit costs 
to account for the change in the time spent for each type of visit in 
2001 compared to 2000. We estimated episode costs by multiplying the 
adjusted per-visit cost for each type of visit by the average mix of 
visits provided in each payment group in a 2001 episode. We also added 
an additional amount for the costs of other services not included in 
the per-visit costs.[Footnote 19] Our methodology assumes that the 
relationship between direct patient care costs and overhead costs has 
remained the same over time and therefore that administrative costs 
have not increased or decreased since the PPS. 

We calculated the average payment as the payment amount for each of 
the 80 payment groups weighted by the proportion of all episodes in 2001
provided within each payment group. 

We interviewed CMS officials and industry representatives from the 
American Association for Homecare, National Association for Home Care,

Subject: General Accounting Office (GAO) Draft report, Medicare Home 
Health Care: Payments to Home Health Agencies Are Considerably Higher 
than Costs (GAO-02-663): 

Thank you for the opportunity to review the above-subject report. 

The GAO report presents data supporting the conclusion that Congress 
should consider retaining the statutorily required reduction to home 
health payments in FY 2003. Although, GAO acknowledges their analysis 
was based on data from the first six months of 2001, their initial 
observations are consistent with our preliminary data analysis for the 
first year of PPS. 

We note, however, the data are susceptible to other interpretations. 
Cost report data for the first year of prospective payment system 
(PPS) are not currently available and will not be available for some 
time. Without that data, it cannot be known with certainty what it 
costs the home health agencies (HHAs) to render the services provided. 

In the April, 2000 report entitled "Medicare Home Health Care: 
Prospective Payment System Will Need Refinement as Data Become 
Available" (GAO-HERS-00-9), GAO suggested that a risk-sharing 
arrangement limiting the amount an home health agency (HHA) can lose 
or gain under a (PPS) would involve a year-end settlement that 
compares an HHA's actual Medicare allowable costs with its total 
Medicare payments. Payments above the costs would be constrained to a 
specific percentage, as would agency losses. Both phases of the PPS 
demonstration included this form of risk-sharing. 

The CMS believes that risk-sharing is administratively incompatible 
with and is conceptually contrary to the principles of PPS. Risk-
sharing was one of many features of early research on PPS that were 
used to entice voluntary participation in the demonstration. 

The GAO proposal would potentially require Medicare to provide 
additional payments to an HHA at the end of the year if the HHA's 
costs were higher than its total PPS payments capped at a certain 
percentage. Or, in the alternative, GAO would require Medicare to 
recoup payments already made to the HHA if the HHA's costs were lower 
than its total PPS payments capped at a certain percentage. These 
proposals are at odds with the most beneficial features of prospective 
payment systems — ensuring that all payments occur in a predictable 
and timely manner A cost-based risk-sharing provision would reinstate 
retrospective reimbursement. 

In addition, the data needed to implement GAO's suggestion are not 
readily available for end-of-the-year adjustments. Agency-specific 
cost report data are required to determine cost margins, and the 
earliest clean cost reports are settled, without fiscal intermediary 
fieldwork or audit work, 18 months after the end of an HHA's cost 
reporting period. For a clean cost report, 18 months after the end of 
an HHA's cost reporting period is the earliest point Medicare would be 
able to compare an HHAs' allowable costs with its total PPS payments. 

Further, the industry has raised issues with regulatory burden 
associated with cost reporting requirements. One of the 
Administration's goals is to the reduce regulatory burden on health 
care providers whenever possible. A risk-sharing provision based on 
cost report data would perpetuate the use of cost reports in their 
current form and hinder attempts to reduce cost reporting burden. It 
would also require continued audit and review functions to a greater 
degree than a PPS system. 

We believe the outlier policy under home health PPS mitigates GAO's 
concerns that HHAs with a disproportionate number of beneficiaries 
with extensive needs are vulnerable to underpayments. Further, CMS has 
the statutory authority to analyze the appropriateness of payments 
through case mix refinement. We will also have a greater understanding 
of whether HHAs are maximizing profits at the expense of quality of 
care versus appropriate efficiencies under a PPS when CMS has complete 
outcome based quality improvement data. CMS will continue its ongoing 
analysis to ensure appropriate levels of service and determine if 
quality of care is compromised, to track changes in agency behavior 
and assess the short-term and longer-term effects of PPS.

Improvement and Protection Act of 2000 (BIPA) (Pub. L. No. 106-554,

account for differences in beneficiary care needs. They reflect three 
dimensions of care: clinical severity, functional severity, and 
service utilization. They are known as home health resource groups 
(HEIRGs).

[8] Beneficiaries are homebound when they have a condition that 
results in a normal inability to leave home except with considerable 
and taxing effort, and absences from home are infrequent or of 
relatively short duration or are attributable to receiving medical 
treatment. 

[9] There were separate limits for each type of visit, e.g., skilled 
nursing and home health aide. 

[10] Section 4603 of BBA, 111 Stat. 467. The Omnibus Consolidated and 
Emergency Supplemental Appropriations Act of 1999 (Pub. L. No. 105-
277, division J, title V, Sec. 5101, 112 Stat. 2681, 2681-914) delayed 
the PPS implementation by 1 year to October 1, 2000. 

[11] The per-beneficiary amount was a blend of each agency's 1994 
average annual payments for treating a Medicare beneficiary and a 
regional or national average annual amount. For agencies that had not 
participated in Medicare for a full year by October 1994, the amount 
was based on the 1994 national median payment. 

[12] If four or fewer visits are provided during the 60-day episode, 
Medicare makes a low-utilization payment adjustment (LUPA) and pays a 
per-visit amount. HHAs receive less than a full episode payment, known 
as a partial episode payment (PEP), if the episode of care is 
interrupted, such as when a beneficiary elects to transfer to another 
BHA, or when a beneficiary is discharged because treatment goals are 
attained but then returns for additional services to the same BHA. 
Payments are also adjusted when the beneficiary experiences a 
significant change in condition (SCIC). An BHA may receive an 
additional outlier payment for certain extremely high-cost episodes.

[17] Less than 16 percent of all episodes in the first 6 months of 
2001 received a LUPA. These were not included in our analysis because 
they are not reflective of episode payments or costs. Episodes that 
required a SCIC adjustment (which may have increased or decreased the 
payment), a PEP adjustment (which reduced the payment), or an outlier 
adjustment (which increased the payment) were included although SCIC, 
PEP, and outlier adjustments were not reflected in our reported 
payments. Episodes with SCIC or PEP adjustments were less than 5 
percent and episodes with outlier adjustments were less than 3 percent 
of all episodes in the first 6 months of 2001. 

[18] See Medicare Program: Prospective Payment System for Home Health 
Agencies, 65 Federal Register 41,128 (2000). HCFA also made several 
additional adjustments to the basic cost-per-visit calculations, 
including increasing the audited cost report data for nonroutine 
medical supplies, and decreasing costs for providers affected by the 
per-visit limits (see 65 Federal Register 41,170). 

[19] The additional services include certain therapies not in the 
visits, additional medical supplies, and costs associated with new 
reporting requirements. See Medicare Program: Prospective Payment 
System for Home Health Agencies, 65 Federal Register 41,128 (2000).
