In December 2003, the Medicare Prescription Drug Improvement and Modernization Act of 2003 (MMA) was signed into law. The United States Pharmacopeial Convention (USP) is named in Section 1860D-4(b)(3)(C)(ii) of the Act, which states:

MODEL GUIDELINES—The Secretary shall request the United States Pharmacopeia to develop, in consultation with pharmaceutical benefit managers and other interested parties, a list of categories and classes that may be used by prescription drug plans under this paragraph and to revise such classification from time to time to reflect changes in therapeutic uses of covered Part D drugs and the additions of new covered Part D drugs.

The responsibility for implementing this provision of MMA rests with the Centers for Medicare and Medicaid Services (CMS). CMS and USP entered into a Cooperative Agreement (18-C-92305/3-01) for the initial development of the Model Guidelines. This activity commenced on May 1, 2004 and concluded on December 31, 2004 with USP’s submission to CMS of its deliverables, including Version 1.0 of the USP Medicare Model Guidelines (Model Guidelines).

As stipulated in the law, USP is also responsible for revising the USP Medicare Model Guidelines on a continuous basis, based on "changes in therapeutic uses of covered Part D drugs and the additions of new covered Part D drugs." Thus, in subsequent years USP and CMS entered into annual Cooperative Agreements that resulted in Versions 2.0, 3.0, and 4.0 of the Model Guidelines and related deliverables, similarly developed through a process that included comprehensive review of available information and evidence, public outreach and input, and deliberation and approval by the USP Council of Experts. Versions 2.0, 3.0, and 4.0 were part of a continuous revision process; Version 5.0 through 8.0 represent a triennial review process and includes consideration of drugs in the US market in v8.0 through November 1, 2019.

Through written correspondence dated July 22, 2019, CMS has confirmed the request for USP to engage in the revision process to update the Model Guidelines to Version 8.0, in order to address the current needs of the Medicare Part D beneficiaries. As a response, USP published MMG v8.0 on February 1, 2020.
