Medicare: Utilization and Expenditures for Complex Wheelchair Accessories
The Medicare fee-for-service (FFS) program spends millions of dollars annually to furnish
wheelchairs and wheelchair accessories to Medicare beneficiaries.1 Based on medical
necessity, Medicare provides coverage for a total of 73 types of wheelchairs and 193
accessories such as headrests and seat cushions. The covered wheelchairs range from basic
standard manual wheelchairs to individually configured power wheelchairs with multiple power
accessories for individuals with permanent or progressive conditions, such as multiple sclerosis.
(See enclosure 1 for a graphic of different types of wheelchairs.) Some manual and power
wheelchairs can accommodate complex rehabilitative technology (CRT) accessories-and are
referred to as CRT wheelchairs.

Both we and the Department of Health and Human Services' Office of Inspector General have
reported that Medicare and its beneficiaries have sometimes paid higher-than-market rates for
power wheelchairs and other durable medical equipment (DME) items.2 To achieve savings on
these items, Congress required the Centers for Medicare & Medicaid Services (CMS)-the
agency that oversees the Medicare program-to phase in a competitive bidding program (CBP)
for certain DME items in which suppliers compete in order to provide certain DME items and
services within designated competitive bidding areas.3 Beginning in 2008, CMS began phasing-
in the CBP by rounds with each round operating in particular geographic areas for a defined
period of time. The CBP started in bidding areas comprised of nine major cities and their
surrounding suburbs and is currently operating in 109 bidding areas. Wheelchairs and
accessories included in the CBP and provided in CBP areas are subject to competitively set
payment rates that must be less than or equal to rates established for the same items by
Medicare's fee schedule.4 The Medicare Improvements for Patients and Providers Act of 2008
terminated the first round of the CBP and excluded a subset of CRT power wheelchairs-those

disabilities and individuals with end-stage renal disease. Wheelchairs and accessories are typically obtained from
durable medical equipment suppliers, who then submit claims for payment to Medicare.
2In August 2009, the U.S. Department of Health and Human Services' Office of Inspector General reported that
Medicare and its beneficiaries paid almost four times the average suppliers' costs to acquire standard power
wheelchairs and almost two times the average suppliers' costs to acquire complex rehabilitation power wheelchair
packages during the first half of 2007. Office of Inspector General, Department of Health and Human Services, Power

grouping of related items used to treat a similar medical condition.

the geographic price differences that are subject to national floor and ceiling payment limits. In the competitive
