H.R. 5571 — Expanding Seniors’ Access to PFAS Testing Act

This section adds blood testing to measure perfluoroalkyl and polyfluoroalkyl substances (PFAS)—ordered by a physician—as a Medicare Part B screening and preventive service under section 1861(ww)(2) of the Social Security Act. It further provides 100 percent payment (with no beneficiary coinsurance or deductible) for such testing furnished on or after January 1, 2028, equal to the lesser of actual charges or the fee schedule amount applicable to preventive services (thus expanding the existing no-cost-sharing requirement for certain preventive services to include PFAS testing).
