State Payment of Medicare Premiums

State Payment of Medicare Premiums

States pay Medicare Part B premiums each month for over 10 million individuals and Part A premium for over 700,000 individuals. This process promotes access to Medicare coverage for low-income older adults and people with disabilities, and it helps states ensure that Medicare is the first and primary payer for Medicare covered services for dually eligible beneficiaries.

Manual for State Payment of Medicare Premiums (formerly called “State Buy-in Manual”)

The Manual for State Payment of Medicare Premiums (formerly called “State Buy-in Manual”) includes instructions and information to states on federal policy, operations, and systems concerning the payment of Medicare Parts A and B premiums (or buy-in) for individuals dually eligible for Medicare and Medicaid. 

CMS has updated chapter one to provide states with additional detail on how to implement policies finalized in the September 2023 Streamlining Medicaid; Medicare Savings Program Eligibility and Enrollment Final Rule (CMS 2421-F). The manual revisions also reflect technical edits related to state buy-in and the MSPs.

The manual is part of the CMS Manual System, specifically Pub. 100-24. It is divided into the following sections:
