The FAST Repairs for Wheelchairs Act prohibits Medicare Advantage plans from requiring prior authorization, prescription approval, or medical documentation before covering repairs to complex rehabilitation technology, primarily wheelchairs and related accessories. The restriction applies to plan years beginning January 1 after the bill is enacted, streamlining the repair approval process for Medicare beneficiaries who use these mobility devices. Prior authorization may still be required for initial medical necessity evaluations, technology replacements due to loss or damage, or when equipment reaches five years of use or the end of its useful life. The bill affects Medicare Advantage plan enrollees who depend on power wheelchairs, manual wheelchairs, and related accessories for mobility. By removing administrative barriers to repairs, the legislation aims to reduce delays in getting essential mobility equipment serviced while allowing insurers to maintain oversight of major replacements and new equipment purchases.
