Program Comments

In FY 2011, HHS is reporting, for the first time, a composite error estimate for the Medicare Prescription Drug Program (Part D), based on CY 2009 payments. The FY 2011 Part D Composite Payment Error Rate combines five component payment error measures: the Medicare Advantage Prescription Drug (MARx) Payment Error (MPE) estimate; the Payment Error relating to Low Income Subsidy status (PELS); the Payment Error Related to Incorrect Medicaid Status (PEMS); the Payment Error Related to Prescription Drug Event Data Validation (PEPV); and the Payment Error related to Direct and Indirect Remuneration (PEDIR). FY 2011 is the first year PEDIR has been measured.  More information on this program can be found in the Agency’s Financial Report.
