🩺 How to Sign Up for Medicare
Medicare is federal health insurance primarily for people 65 and older and for certain younger people with qualifying disabilities or conditions. Enrollment timing depends on Social Security benefits, current employment coverage, disability, and other circumstances.
Use Medicare's official sign-up tool to identify the correct enrollment period. Part A and Part B enrollment is handled through the Social Security Administration, not by a private plan salesperson.
After Parts A and B, compare Original Medicare and Medicare Advantage, drug coverage, provider networks, total annual costs, and supplemental coverage. Free State Health Insurance Assistance Program counseling is available.

Can I delay Part B with employer coverage?
Sometimes. The rules depend on current employment and plan type; COBRA and retiree coverage may not protect against a late penalty.
