PLASMA Act

HR 1476, the PLASMA Act, adjusts discount rates for plasma-derived drugs under Medicare Part D starting in 2026. It sets gradually decreasing discount percentages (from 99% down to 90% by 2030) for these specific drugs when beneficiaries reach their annual out-of-pocket spending threshold. The bill directly affects Medicare Part D beneficiaries using plasma-derived biological products (drugs made from human blood or plasma) and the manufacturers of those drugs. Certain drugs for low-income subsidy beneficiaries and small manufacturers are excluded from these discount provisions. The law phases in these changes over several years to align with existing Medicare Part D cost-sharing rules.
