Medicare Advantage: Private Health Plans in Medicare

Medicare provides federal health insurance for 43 million
people who are aged or disabled or who have end-stage
renal disease. Most receive services through the tradi-
tional fee-for-service (FFS) part of the program, which
pays providers a set fee for each covered service (or bundle
of services). Participants can choose their providers and
are not required to obtain prior authorization for any
covered service.
Medicare beneficiaries have the option of enrolling in
Medicare Advantage-the program through which pri-
vate plans participate in Medicare-rather than receiving
their care through the FFS program.1 They may choose
to do so because such plans provide additional benefits
beyond those available within traditional Medicare,
including coverage for services not covered by FFS Medi-
care (for instance, dental services) and cash rebates of pre-
miums or reduced cost-sharing. As of June 2007, about
18 percent of beneficiaries are enrolled in Medicare
Advantage plans.2 This brief describes how those private
plans function, how they are paid, how their costs com-
pare with the costs of traditional Medicare, and how
those costs vary by geographic area.
In summary:
 Enrollment in Medicare Advantage is growing rapidly,
particularly in a relatively unmanaged type of plan
called private fee for service (PFFS).
  Medicare's payments for beneficiaries enrolled in
Medicare Advantage plans are higher, on average, than
what the program would spend if those beneficiaries
were in the FFS sector-so shifts in enrollment out of
the FFS program and into private plans increase net
Medicare spending.
1. Medicare Advantage is also called Part C. Previously, the program
had been called Medicare+Choice.
2. Another 1 percent of beneficiaries are enrolled in other types of
group plans, including cost-reimbursed plans, health care prepay-
ment plans, a program of all-inclusive care for the elderly, and
demonstration plans.

 The difference in costs relative to those for the tradi-
tional FFS program is particularly large for PFFS
plans.
 The additional cost to the government for Medicare
Advantage plans subsidizes the beneficiaries who
enroll in such plans, which fuels the plans' growth in
enrollment and raises costs for Medicare beneficiaries
who do not participate in Medicare Advantage.
 Reducing the payment differential between Medicare
Advantage and the FFS program could result in
substantial savings to the Medicare program. But it
would also diminish the supplemental benefits and
cash rebates that Medicare Advantage plans can offer
to enrollees and lessen enrollment in those plans.
Lowering payments to those plans would slightly
reduce the standard premiums for Part B of Medicare
(Supplementary Medical Insurance) and delay the
exhaustion of the trust fund that supports Part A
(Hospital Insurance).
