United States Pharmacopeia (USP). Medicare Prescription Drug Benefit Model Guidelines Source Information
The Medicare Model Guidelines were developed and are maintained by the U.S. Pharmacopeial Convention (USP) in conjunction with the Centers for Medicare and Medicaid Services (CMS).
Medicare Model Guidelines were developed as a result of the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA) to provide categories and classes of drugs covered by Medicare Part D.
Drugs are organized hierarchically by pharmacologic class within therapeutic categories. Drugs and their salt and ester variations are grouped by drug type within the pharmacologic classes.
Medicare Model Guidelines are used by CMS, Medicare beneficiaries, and Part D drug plan companies.
Medicare Model Guidelines are updated every three years.
