Part D Beneficiary Appeals Fairness Act

Part D Beneficiary Appeals Fairness Act - Amends part D (Voluntary Prescription Drug Benefit Program) of title XVIII (Medicare) of the Social Security Act, with respect to a prescription drug plan (PDP) that provides for any tiered cost-sharing within a formulary (including a structure that provides for different co-payment or coinsurance amounts for drugs in different tiers included within the formulary), to authorize a Medicare part D eligible individual enrolled in the plan to request an exception to the tiered cost-sharing structure.

States that in no case may the Secretary of Health and Human Services (HHS) allow a PDP sponsor to make any formulary tier of the tiered cost-sharing structure (including a formulary tier used for very high cost or unique items) ineligible for lower-cost sharing through an exception.
