This bill proposes to expand Medicare coverage by classifying cranial prostheses , commonly known as wigs, as durable medical equipment. It amends Section 1861(n) of the Social Security Act to include these items, provided they are certified as medically necessary. For coverage, a dermatologist, oncologist, or attending physician must provide written certification that the cranial prostheses are needed for a proposed course of rehabilitative treatment or for hair loss resulting from specific health conditions. These conditions include autoimmune diseases, cancer, or chemotherapy . A conforming amendment to Section 1862(a)(1) clarifies that cranial prostheses not certified in this manner would not be covered, ensuring proper medical oversight for eligibility.
