Not everyone gets Medicare automatically, and age alone does not may provide it

Medicare is available to people who meet specific conditions set by federal law. The most common path is being 65 or older, but you also need either a work history in Social Security or to be a spouse or dependent of someone who does. Younger people can get Medicare if they have received Social Security Disability Insurance (SSDI) for 24 months, have end-stage renal disease (ESRD), or have amyotrophic lateral sclerosis (ALS). straightforward reaching 65 does not automatically enroll you — you must take action during your enrollment window, or you may face permanent penalties on your premiums.

The rules are federal, but the way you prove you meet them is through Social Security. You cannot walk into a Medicare office and sign up. You work through Social Security, either online, by phone, or in person at a local office. Understanding which path applies to you saves time and prevents costly mistakes.

Age 65 and the Social Security work requirement

The most straightforward path to Medicare is turning 65 with a work history. You need at least 40 credits under Social Security, which typically means working for about 10 years. If you worked that long and paid Social Security taxes, you are may be able to access for Medicare Part A (hospital insurance) at 65, even if you have not yet claimed Social Security retirement benefits.

You do not have to be retired to get Medicare at 65. You can still be working full-time. What matters is the work history, not your current employment status. If you have fewer than 40 credits, you may still be may be able to access as a spouse or dependent, which is covered below. You can check your work credits by creating an account on ssa.gov or calling Social Security at 1-800-772-1213.

may be able to access through a spouse or ex-spouse

If you do not have 40 work credits yourself, you may be may be able to access based on someone else's record. You can get Medicare at 65 if you are the spouse of someone 65 or older who is may be able to access, or if you are a dependent child of an may be able to access person. The spouse does not have to have claimed benefits yet — they just need to be may be able to access.

Ex-spouses can also may have access to this way. If you were married for at least 10 years, are now divorced, and are 65 or older, you can get Medicare based on your ex-spouse's work record. You do not need their permission or even their knowledge. This applies whether your ex-spouse has claimed benefits or not. You will need to provide proof of the marriage and divorce when you contact Social Security.

Younger people: SSDI, ESRD, and ALS

You do not have to wait until 65 if you receive Social Security Disability Insurance (SSDI). After you have been on SSDI for 24 months, you become may be able to access for Medicare regardless of age. This means a 30-year-old on SSDI can get Medicare once the 24-month waiting period ends. Social Security will contact you automatically when you reach the 24-month mark, but you still need to enroll in Part B if you want medical insurance coverage.

Two medical conditions bypass the age and work-history requirements entirely. If you have end-stage renal disease (ESRD) — permanent kidney failure requiring dialysis or transplant — you are may be able to access for Medicare when ready, even at any age and without a work history. The same applies if you have amyotrophic lateral sclerosis (ALS), also called Lou Gehrig's disease. You become may be able to access as soon as you are approved for Social Security Disability Insurance based on ALS, with no 24-month wait. Your doctor or dialysis center can help you start the Social Security process.

Citizenship and residency requirements

You must be a U.S. citizen or a lawful permanent resident (green card holder) to get Medicare. If you are a lawful permanent resident, you must have held that status for at least five consecutive years when ready before you turn 65. Gaps in your permanent resident status reset the clock.

If you are not yet a permanent resident but are in the United States on another visa, you cannot get Medicare based on age. You may be able to get it through SSDI, ESRD, or ALS if you meet those conditions, but the citizenship requirement still applies to those pathways as well. Bring your green card or citizenship papers when you contact Social Security to prove your status.

What happens if you do not meet Medicare requirements

If you are 65 or older but do not have the work history, spousal may be able to access, or citizenship status to get Medicare, you have other options. You can purchase health insurance through the Affordable Care Act (ACA) marketplace at healthcare.gov. You may also be able to buy into Medicare Part A by paying a monthly premium, though this is uncommon and expensive — the premium can be several hundred dollars per month depending on your work history.

Some states offer programs for uninsured older adults, and community health centers provide care on a sliding fee scale based on income. Contact your local Area Agency on Aging to learn what programs exist in your region. You can also call 211 to be connected to local resources. These alternatives may cost less than buying into Medicare Part A on your own.

Enrollment timing and penalties

Even if you are may be able to access, you must enroll during your Initial Enrollment Period to avoid permanent penalties. This window is seven months long: the three months before the month you turn 65, the month itself, and the three months after. If you miss this window and do not have a valid reason (called a "may have access to event"), you will pay a higher premium for Part B for as long as you have Medicare — typically 10 percent more per year of delay.

Part A (hospital insurance) usually has no premium if you have 40 work credits, so the penalty applies mainly to Part B (medical insurance). If you are still working and have employer coverage, you may have a grace period to enroll without penalty, but you must tell Social Security about your employer coverage to protect yourself. The penalty is permanent, so missing your window is costly over time.

Frequently Asked Questions

Can I get Medicare if I worked outside the United States?

Work outside the U.S. does not count toward the 40 Social Security credits you need. However, some countries have totalization agreements with the U.S. that allow work in those countries to count. You would need to contact Social Security directly to learn about your country has such an agreement and how to report that work.

What if I am 65 but still working and do not want Medicare yet?

You can delay enrolling in Part B (medical insurance) if you have employer coverage through your job. You must tell Social Security that you are still working and covered by your employer. If you do not report this, you will still face the late-enrollment penalty. Part A (hospital insurance) has no penalty for delay, so you can skip it if you prefer.

Can I get Medicare if I am a permanent resident but have not lived in the U.S. for five years?

Not at 65. You must have been a permanent resident for five consecutive years before your 65th birthday. However, if you become may be able to access through SSDI, ESRD, or ALS before that five-year mark, those pathways do not have the same residency requirement — only the citizenship requirement applies.

What if I was married for less than 10 years — can I still use my ex-spouse's record?

No. The law requires at least 10 years of marriage to be may be able to access for Medicare based on an ex-spouse's work record. If you were married for nine years and nine months, you do not meet the requirement. However, you can still get Medicare if you have your own 40 work credits.

Do I lose Medicare if I move out of the United States?

You can keep Medicare Part A and Part B if you move abroad, but coverage is limited. Medicare generally does not pay for care outside the U.S., except in very specific situations like emergency care in Canada or Mexico near the U.S. border. You should research supplemental coverage or local health insurance in your destination country before you move.
