Before the enactment of Medicare Part D, 22 states funded SPAPs while six states operated waiver programs funded jointly by state and federal governments through Medicaid (see Medicaid Waiver). With Part D in operation, most states have begun providing wrap-around benefits to coordinate and ease the enrollment of their Medicare beneficiaries by, for example, covering deductibles, co-insurance or the gap in Medicare Part D coverage.
