Who Medicare covers, and how to learn about you're one of them

Medicare covers people who are 65 or older, people under 65 with certain disabilities, and people of any age with end-stage renal disease or ALS. You don't need to wait until you turn 65 to find out whether you meet the requirements — you can check your status now using your Social Security account or by calling Social Security directly. The fastest way is online; the most thorough way is to speak with someone who can review your work history.

Your work history matters because Medicare is tied to Social Security credits. You earn one credit for each quarter you work and pay Social Security taxes, up to four credits per year. Most people need 40 credits total (roughly 10 years of work) to get Medicare at 65. If you've worked less than that, you may still be covered as a spouse, widow, or widower — but you'll need to verify that separately.

Key Takeaways

  • You can check your Medicare status online through your Social Security account at ssa.gov without calling or visiting an office.
  • Medicare requires 40 Social Security credits (about 10 years of work) for most people, but spouses and widows may may have access to with fewer credits.
  • If you're under 65, you can still check whether you meet the disability or end-stage renal disease requirements by contacting Social Security.
  • Your Social Security Statement shows your work credits and estimated benefits, which is the document you need to verify your Medicare path.

Check your work credits online through Social Security

Go to ssa.gov and create or log into your Social Security account. Once you're logged in, select "Earnings Record" to see your complete work history and the number of credits you've earned. This is the fastest way to confirm whether you have the 40 credits needed for Medicare at 65. The page shows credits year by year, so you can spot any gaps or errors.

If you see a year where you earned fewer credits than expected, or no credits at all, write down the year and the amount shown. You'll need this information if you contact Social Security to correct the record. Errors do happen — a wage report might have been filed under a slightly different name, or an employer might have reported incorrectly.

Your Social Security Statement also appears in your account. This document lists your estimated retirement benefit at 62, your full retirement age, and your benefit at 70. It also shows your total credits to date. Print or read this statement; you may need it when you turn 65 and enroll in Medicare.

Call Social Security to review your record if you're unsure

If you don't have an online account, or if you want someone to walk through your work history with you, call Social Security at 1-800-772-1213. Have your Social Security number ready. Tell the representative you want to verify your credits for Medicare. They can tell you on the spot whether you have 40 credits, and if not, how many you have and what your options are.

This call is especially important if you've worked under more than one name (due to marriage, for example), worked for a railroad, or worked for a government employer that didn't pay into Social Security. These situations sometimes create gaps or duplicate records that affect your credit count.

The wait time to speak with someone is usually shorter in the early morning or mid-week. If you reach a busy signal, try again later rather than waiting on hold for an hour.

Understand the different paths to Medicare coverage

The most common path is age 65 with 40 credits. If you have worked and paid Social Security taxes for about 10 years, you'll meet this requirement. You can enroll in Medicare starting three months before your 65th birthday.

If you're married to someone with 40 credits, you may be covered as a spouse even if you have fewer than 40 credits yourself. You must be at least 62 years old. Contact Social Security to confirm this applies to you, because the rules depend on when you were married and your spouse's work history.

If you're a widow or widower, you may be covered based on your deceased spouse's work record. You must be at least 60 years old (50 if disabled). Call Social Security to verify your status.

If you're under 65 and disabled, you may be covered if you have enough credits and your condition meets Social Security's definition of disability. This is a separate review; contact Social Security's disability office to learn more.

If you have end-stage renal disease (permanent kidney failure requiring dialysis or transplant) or ALS (amyotrophic lateral sclerosis), you may be covered regardless of age or credits. You'll need medical documentation. Ask your nephrologist or neurologist to help you contact Social Security.

What to do if you don't have 40 credits

If you have fewer than 40 credits and don't may have access to as a spouse or widow, you have two options: continue working to earn more credits, or pay for coverage yourself. You can earn up to four credits per year, so if you're close, working a few more years may get you there.

If you choose to pay for coverage, you can buy Part A (hospital insurance) and Part B (medical insurance) directly from Medicare starting at age 65. The cost depends on how many credits you have. People with 30 to 39 credits pay a reduced premium; people with fewer than 30 credits pay the full premium. Call 1-800-MEDICARE (1-800-633-4227) to learn the exact cost for your situation and to enroll.

This option is less common but available. It's worth exploring if you immigrated later in life or had gaps in your work history.

Correct errors in your Social Security record

If you spot a missing year, a year with fewer credits than you earned, or a wage amount that looks wrong, you can request a correction. You have a limited window: generally three years, three months, and 15 days from the end of the year in which the wages were earned. After that, the record is locked unless you have proof (a W-2, pay stub, or tax return).

To request a correction, call Social Security at 1-800-772-1213 or visit your local Social Security office. Bring the proof with you — a copy of your W-2 or tax return for that year. If your employer is still in business, Social Security may contact them to verify the wage report.

Corrections can take several weeks to process. Start this as soon as you notice the error, especially if you're within a few years of turning 65.

Plan your enrollment once you confirm your status

Once you've confirmed you meet Medicare's requirements, mark your calendar for three months before your 65th birthday. That's when you can enroll in Medicare Part A and Part B. You can enroll online at ssa.gov, by phone at 1-800-MEDICARE, or in person at your local Social Security office.

If you're still working at 65 and have health insurance through your employer, you may be able to delay enrollment without penalty — but you'll need to confirm this with your employer's benefits office and with Medicare. Delaying without may have access to for an exception can result in a permanent premium increase.

Keep your Social Security Statement and your credit record printout in a safe place. You'll refer to them when you enroll, and you may need them later if questions arise about your coverage date.

Frequently Asked Questions

What if I worked in another country — do those years count toward Medicare?

Generally, no. Social Security credits are based on work in the United States and taxes paid to the U.S. Social Security system. However, the U.S. has totalization agreements with some countries that allow work in those countries to count toward your credits. Call Social Security at 1-800-772-1213 to ask whether your country has an agreement and whether your work qualifies.

Can I check my spouse's credits to see if I may have access to as a spouse?

You can't access your spouse's account directly, but Social Security can tell you. Call 1-800-772-1213 and ask whether you're covered as a spouse based on your spouse's work record. Have your spouse's Social Security number ready. The representative will review both records and give you a clear answer.

What happens if I never worked — can I still get Medicare?

If you're 65 or older and have no work credits, you cannot get Medicare Part A (hospital insurance) for free. You may be able to buy it, but the cost is high. If you're married, you may be covered as a spouse if your spouse has 40 credits. Contact Social Security to explore your options.

How long does it take to get a correction added to my record?

straightforward corrections (like a missing wage report) usually take four to six weeks. Complex corrections (like disputes with an employer) can take several months. Start the process as soon as you notice the error, especially if you're within two years of turning 65.

Do I need to do anything before I turn 65, or can I wait until my birthday?

You can enroll up to three months before your 65th birthday, and you should — this ensures your coverage starts on your birthday month. If you wait until after your birthday to enroll, your coverage may start later, and you could face a gap in health insurance. Check your status now so you're ready to enroll when the window opens.
