To amend title XVIII of the Social Security Act to provide coverage for wigs as durable medical equipment under the Medicare program, and for other purposes.

HR 4034 would add cranial prostheses (such as medical wigs) to Medicare's list of covered durable medical equipment. It requires a dermatologist, oncologist, or attending physician to certify in writing that the prosthesis is medically necessary as part of rehabilitative treatment. This change directly affects Medicare beneficiaries experiencing hair loss due to medical conditions like cancer treatment who need these prostheses for health reasons. The bill does not cover cosmetic wigs but specifically targets medically necessary cranial prostheses under existing Medicare coverage rules.
