The answer
How do I sign up for Medicare?
You sign up for Medicare through Social Security, online at ssa.gov, by phone, or in person at a Social Security office; Medicare itself does not handle enrollment.
The best time is your Initial Enrollment Period, the seven-month window around your 65th birthday. If you already receive Social Security benefits, you are usually enrolled automatically in Part A and Part B. If you are not yet drawing Social Security, you have to apply yourself. After you have Part A and Part B, you can separately choose added coverage like a Part D drug plan, a Medicare Advantage plan, or a Medigap supplement. To talk through which added coverage fits your situation, reach out to a licensed Goodsurance advisor at 1-888-301-8091 (TTY 711), Mon to Fri 8 am to 5 pm PT.
