Medicare starts at age 65 for most people

You become may be able to access for Medicare at age 65, regardless of your work history or income. This is the standard may be able to access age set by federal law. You do not have to retire to sign up — you can keep working and still enroll in Medicare when you turn 65.

Some people become may be able to access before 65. If you have received Social Security Disability Insurance (SSDI) for 24 months, you become may be able to access at any age. If you have End-Stage Renal Disease (ESRD) — permanent kidney failure requiring dialysis or transplant — you may be may be able to access regardless of age. If you have ALS (amyotrophic lateral sclerosis), you become may be able to access when ready without waiting.

The enrollment window around your 65th birthday is critical. If you miss it, you may pay a permanent penalty on your premiums. The window opens three months before the month you turn 65 and closes three months after.

Key Takeaways

  • You become may be able to access for Medicare at age 65, and you can enroll starting three months before your birthday.
  • If you receive SSDI, you become may be able to access after 24 months of receiving benefits, regardless of your age.
  • People with End-Stage Renal Disease or ALS may become may be able to access before 65 without the SSDI waiting period.
  • Missing your enrollment window can result in a permanent increase to your Part B and Part D premiums.

How the enrollment window works around age 65

Your Initial Enrollment Period (IEP) is a seven-month window: three months before the month you turn 65, the month you turn 65, and three months after. During this time, you can enroll in Medicare Part A (hospital insurance) and Part B (medical insurance) without penalty.

If you are still working and covered by your employer's health plan, you may be able to delay Part B enrollment without penalty — but only if your employer has 20 or more employees. You will need to show proof of that coverage when you do enroll. Part A has no penalty for delay if you are covered by an employer plan, but Part B does unless you meet the employer coverage exception.

If you miss your IEP and do not have employer coverage, you will pay a Part B late enrollment penalty for as long as you have Medicare. The penalty is 10 percent of the standard Part B premium for each full 12-month period you were may be able to access but not enrolled. This penalty stacks — if you were may be able to access for three years without enrolling, your penalty is 30 percent of the premium, permanently.

may be able to access before age 65: SSDI and other paths

If you receive SSDI, you automatically become may be able to access for Medicare after you have been receiving benefits for 24 consecutive months. You do not have to reach 65. The 24 months is measured from the month your SSDI benefits began, not from when you applied.

Social Security will contact you about three months before you become may be able to access and will enroll you automatically in Part A and Part B unless you decline. If you want to delay Part B, you must tell Social Security in writing before your may be able to access date. Unlike the employer coverage exception for people turning 65, there is no exception for SSDI recipients — if you decline Part B and later enroll, you will pay the late enrollment penalty.

If you have ESRD, you become may be able to access for Medicare regardless of age. You must be a U.S. citizen or permanent resident, and you must be receiving dialysis or have received a kidney transplant. Your may be able to access begins the first day of the month in which you start dialysis or the month of your transplant. You have a special enrollment period that lasts 12 months after ESRD may be able to access begins, so you can enroll late without the standard penalty.

If you have ALS, you become may be able to access when ready without any waiting period. You do not have to be receiving SSDI. You will need medical documentation of your diagnosis, and you can enroll at any time.

What happens if you are still working at 65

You can work and be on Medicare at the same time. There is no earnings limit — you can earn any amount and still be may be able to access. However, you must still enroll during your Initial Enrollment Period to avoid the Part B penalty.

If your employer has 20 or more employees and offers health insurance, you can delay Part B enrollment without penalty as long as you are actively employed and covered by that plan. Once you or your spouse stops working, or your employer coverage ends, you have eight months to enroll in Part B without penalty. This is called the Special Enrollment Period (SEP) for employer coverage.

Part A (hospital insurance) does not have a penalty for delay if you have employer coverage, so you can delay that too. However, you must enroll in Part A within eight months of losing employer coverage, or you will face a penalty on Part A premiums.

Medicare age rules for spouses and dependents

Your spouse becomes may be able to access for Medicare at age 65, regardless of your age. They have their own Initial Enrollment Period based on their birthday, not yours. If your spouse is younger than 65 and you are on Medicare, they cannot be added to your Medicare coverage — they must have their own health insurance until they turn 65.

Adult children and other dependents do not become may be able to access for Medicare based on a family member's age. They must meet their own may be able to access criteria: age 65, SSDI for 24 months, ESRD, or ALS.
