Notes
Medicare Part D is a voluntary outpatient prescription drug benefit for people with Medicare, provided through private plans approved by the federal government. Beneficiaries can choose to enroll in either a Stand-alone prescription drug plan (PDP) to supplement traditional Medicare or a Medicare Advantage prescription drug plan (MA-PD), mainly HMOs and PPOs, that cover all Medicare benefits including drugs. For more information on Medicare Part D, see KFF’s Overview of the Medicare Part D Prescription Drug Benefit.
United States total includes enrollment in the territories.
