The Centers for Medicare and Medicaid Services (CMS) has finished mailing new cards to Medicare patients in California. If your Medicare patient says they did not get their card, you can print and give them the “Still Waiting for Your Card?” handout in English or Spanish. You can also instruct them to call CMS at (800) 633-4227. In the meantime, physicians can continue to use the Health Insurance Claim Number (HICN). The transition period to the new Medicare Beneficiary Identifiers (MBI) ends on January 1, 2020. For more information, go to https://www.cms.gov/medicare/new-medicare-card/nmc-home.html.
