State Pharmaceutical Assistance Programs
All other forms of drug coverage, including Part D, are primary to coverage provided by a SPAP. That is, a SPAP will only cover medications after any other drug coverage is applied to the cost of that drug. Additionally, payments made by a SPAP to cover drugs that are on the plan’s formulary, but are needed during the coverage gap (“doughnut hole”), count towards TrOOP for the Part D plan. As of February, 2009, 24 states and territories offer qualified SPAPs that provide some level of coverage to SPAP enrollees who are also enrolled in a Part D plan.
