Do I Automatically Get Medicare When I Turn 65?

When do you need to sign up yourself?

You usually need to actively sign up for Medicare if you are turning 65 and are not yet getting Social Security or Railroad Retirement Board benefits. In that situation, Medicare does not simply start because you had a birthday.

You sign up for Medicare Part A and Part B through Social Security. If you are 65 or older, Social Security says you can enroll online for Parts A and B, or for Part A only, depending on your situation.

Some people choose to delay Part B if they have qualifying current employer group health coverage, but that depends on the type of coverage and individual circumstances.

What is your Initial Enrollment Period?

Your first chance to sign up for Medicare is usually your Initial Enrollment Period. Medicare.gov describes this as a 7-month period that starts 3 months before you turn 65, includes the month you turn 65, and ends 3 months after the month you turn 65.

If you are not automatically enrolled, this is the main window to sign up for Part A and Part B. Missing this period may affect when coverage starts and may lead to a late enrollment penalty unless you qualify for a Special Enrollment Period.

What if you are still working at 65?

If you or your spouse are still working when you turn 65 and you have current employer group health coverage, Medicare enrollment can work differently. Medicare.gov says some people may be able to wait to sign up for Part B without a late enrollment penalty.

However, not every type of coverage lets you safely delay Part B. Retiree coverage, COBRA, Marketplace coverage, or other coverage may not work the same way as current employer group health coverage. Ask the employer benefits administrator how your coverage coordinates with Medicare before deciding whether to delay Part B.

Does automatic enrollment include all parts of Medicare?

Automatic enrollment at 65 generally refers to Medicare Part A and Part B, not every Medicare option. Start with our Medicare 101 guide for a clear overview of how Medicare works.

• Part A helps cover inpatient hospital care and related services.
• Part B helps cover doctor services, outpatient care, and other medical services.
• Part D is prescription drug coverage and is separate from Original Medicare.
• Medicare Advantage is another way to receive Medicare coverage through a private plan approved by Medicare.
• Medigap is supplemental insurance that can help pay some Original Medicare out-of-pocket costs.

If you are automatically enrolled in Part A and Part B, you may still need to make separate decisions about prescription drug coverage, Medicare Advantage, or Medigap.

What exceptions should you know about?

Medicare rules can depend on where you live and why you qualify. For example, Medicare.gov states that people who live in Puerto Rico or outside the U.S. may get Part A automatically but need to sign up for Part B if they want it.

People younger than 65 may also qualify for Medicare because of certain disabilities, End-Stage Renal Disease, or ALS. Those rules are different from the standard age-65 enrollment process.

The safest approach is to check your exact situation before your 65th birthday, especially if you are delaying Social Security, working past 65, or covered by another health plan.
