Start with official enrollment guidance
Many people first become eligible for Medicare around age 65. The Initial Enrollment Period generally includes the three months before your birthday month, that month, and the three months after. Some circumstances change the timing.
Confirm your start date
Your sign-up date and circumstances affect when coverage starts. Check Medicare.gov or contact Medicare for the start date that applies to you.
If you have other coverage
If you are still working or have other coverage, contact Medicare and your employer benefits office before deciding when to enroll. Keep any notices and written instructions.
Prepare your questions
Write down your questions about enrollment dates, existing coverage, and who to contact. Your local SHIP can provide free, impartial counseling.
