CMS has started mailing new Medicare cards to people with Medicare who live in Wave 2 states and territories: Alaska, American Samoa, California, Guam, Hawaii, Northern Mariana Islands, and Oregon. We continue to mail new cards to people who live in Wave 1 states, as well as nationwide to people who are new to Medicare.
On June 1, the Railroad Retirement Board (RRB) will mail the new Medicare cards to all people who get RRB benefits, nationwide.
Once people with Medicare get their new Medicare cards, they can start using them right away. Healthcare providers and suppliers can use either the former Social Security-based Health Insurance Claim Number or the new alpha-numeric Medicare Beneficiary Identifier through December 31, 2019
Review new MLN Matters® Special Edition Article: Includes information on MBI changes initiated by people with Medicare, their authorized representatives, or CMS, as well as related eligibility and claims processing information.
Direct people with Medicare to Medicare.gov/NewCard for information about the mailings and to sign up to get email about the status of card mailings in their state
