Will Medicare Enrollment Be Automatic When You Turn 65?

When enrollment may be automatic

People already receiving certain Social Security or Railroad Retirement Board benefits before becoming eligible are generally enrolled automatically in Medicare Part A and Part B and receive a welcome packet before coverage begins. Do not assume: review the packet and confirm your Medicare number, effective dates, name, address, and whether Part B is included.

When you may need to apply

If you are not receiving Social Security benefits and are not applying for them yet, you generally need to sign up for Medicare yourself. Social Security recommends applying about three months before the 65th birthday when you want coverage to begin then. Birthday-on-the-first-of-the-month rules and other eligibility situations can affect timing.

Review Part B carefully

Part B has a monthly premium. Do not decline or delay it based on a general assumption that employer, retiree, COBRA, Marketplace, or other insurance is sufficient. Employer size, active-employment status, creditable drug coverage, and the exact coverage type can affect coordination, penalties, and Special Enrollment Period rights.

Check the welcome packet

Read the Medicare welcome packet promptly and confirm effective dates and personal information. Follow the included instructions if something is incorrect. People residing in Puerto Rico or outside the United States should pay particular attention because Social Security explains that Part B enrollment may require an affirmative election.

Build your personal checklist

• Confirm enrollment dates using your birthday and current coverage.

• Keep written records from Social Security, Medicare, employers, and plans.

• Compare providers, prescriptions, total costs, and coverage rules.

• Use current official documents because rules and plan details can change.
