  • You need this first Original Medicare. You need both Medicare Part A and Part B, and you must live in the plan's area.

How to apply

Request to join a Medicare health or drug plan

Only the person or their legal representative can ask to join. The plan's own phone line and website also take requests.

The same application can also ask for Chronic Condition Special Needs Plan (C-SNP), Dual Eligible Special Needs Plan (D-SNP / Medi-Medi), Institutional Special Needs Plan (I-SNP) and Medicare Part D and other drug coverage.

Getting help

You start this yourself

Only you can choose and join a plan. A guardian, or someone with legal power to make your health decisions, may join for you. Others can help, but the choice and the request must be yours. HICAP gives free, unbiased help.

Only you, or someone with legal authority for you, can sign.

What happens after you apply

Coming changes

  • Starting January 4, 2027: Some people who are not citizens lose Medicare on January 4, 2027. Citizens and green card holders keep it. So do Cuban or Haitian entrants and some Pacific island residents. Social Security writes first to people who will lose it. Their plan ends too.
