Not everyone qualifies for Medicare

Medicare is a federal health insurance program, but it is not automatic for all Americans. You must meet specific requirements based on age, work history, disability status, or medical condition. Most people become covered at 65, but younger people with certain disabilities or conditions can join earlier. If you do not meet any of these categories, you will need to find coverage through another source—your employer, the marketplace, Medicaid, or a private plan.

The key difference from other programs is that Medicare is tied to your own work record or your spouse's work record, not to your income or savings. You could be wealthy and still not may have access to; you could be poor and still may have access to. Understanding which category you might fall into helps you plan ahead and know when to contact Social Security or Medicare.

Key Takeaways

  • You generally become covered by Medicare at age 65 if you or your spouse paid Medicare taxes for at least 10 years of work.
  • People under 65 can join Medicare if they have been receiving Social Security disability benefits for 24 months, or if they have end-stage renal disease or ALS.
  • If you do not have a work history of at least 10 years, you may not may have access to for Medicare even at 65, and will need to explore other coverage options.
  • Signing up late without a valid reason can result in permanent penalties on your monthly premium, so knowing your important date matters even if you are not yet 65.

Age 65 and the 10-year work requirement

The most common path to Medicare is turning 65. However, you must have worked and paid Medicare taxes for at least 10 years (40 quarters) to may have access to. This does not have to be continuous—gaps are fine as long as the total adds up. If you worked under your own name and paid self-employment tax, those years count. If you worked for an employer who withheld Medicare tax from your paycheck, those count too.

If you are married, you can also may have access to based on your spouse's work record, even if you never worked yourself or worked fewer than 10 years. You must be at least 62 years old and married for at least one year. Your spouse does not have to be 65 yet—they just need to be old enough that they could claim Social Security.

If you reach 65 and do not have 10 years of work history, you do not automatically get Medicare. You will need to look at Medicaid (which is income-based and run by your state), marketplace insurance, or coverage through a current employer or family member's plan.

Disability and Medicare before age 65

You can join Medicare before 65 if you have been receiving Social Security Disability Insurance (SSDI) for 24 months. The 24-month clock starts from the month you were approved for SSDI, not from when you applied. Once those 24 months pass, Medicare Part A and Part B begin automatically—you do not have to do anything.

There is one exception: if you are blind, you can join Medicare when ready upon approval for SSDI, without waiting 24 months. Blindness is defined by Social Security's specific standards, not by your doctor's assessment alone.

If you receive Supplemental Security Income (SSI) instead of SSDI, the rules are different. SSI is a needs-based program, and you may be covered by Medicaid instead, depending on your state. Contact your local Social Security office to understand which program you are in and what health coverage you might have.

End-stage renal disease and ALS

Two medical conditions allow you to join Medicare regardless of age or work history: end-stage renal disease (ESRD) and amyotrophic lateral sclerosis (ALS). If you have ESRD and need dialysis or a kidney transplant, you become covered by Medicare. If you have been diagnosed with ALS, you become covered when ready upon diagnosis—you do not have to wait for disability approval or work history.

For ESRD, your coverage typically begins the first day of the month you start dialysis, or the month of your transplant. If you are already on Medicare for another reason, your ESRD coverage adds to what you already have. For ALS, coverage begins the first day of the month you are diagnosed, as long as you file the proper paperwork with Social Security.

Government employees and railroad workers

Most government employees—federal, state, and local—pay into Medicare just like private-sector workers. However, some older government employees hired before certain dates may have been exempt from Medicare taxes. If you are in this situation, you may not have Medicare coverage at 65 unless you worked other jobs that did pay Medicare tax.

Railroad workers have their own retirement system, the Railroad Retirement Board, which coordinates with Medicare. If you worked for a railroad, contact the Railroad Retirement Board directly to understand your coverage, because the rules differ from standard Social Security.

Non-citizens and Medicare

You must be a U.S. citizen or a permanent resident (green card holder) to join Medicare. If you are a permanent resident, you must also have lived in the United States for at least five years. Temporary visa holders, undocumented immigrants, and people in other immigration statuses do not may have access to for Medicare, even if they have worked and paid Medicare taxes.

If you are a permanent resident and meet the five-year residency requirement, your work history is counted the same way as a citizen's. You need 10 years of work history to may have access to at 65, or you can may have access to through disability or medical conditions using the same rules as citizens.

What to do if you do not may have access to for Medicare

If you are 65 or older and do not have 10 years of work history, your options depend on your income and state. Medicaid is available in all states for people with low income, though the income limits vary by state. The Health Insurance Marketplace (Healthcare.gov or your state's marketplace) offers plans to anyone regardless of work history, and you may be able to lower your monthly cost if your income is low enough.

If you are under 65 and do not may have access to for Medicare through disability or a medical condition, you can purchase marketplace insurance, stay on a family member's employer plan if you are may be able to access, or look into Medicaid if your income qualifies. Some people also remain on their employer's plan past 65 if they are still working—you do not have to sign up for Medicare when ready if you have group health coverage through your job.

Frequently Asked Questions

Can I get Medicare if I never worked?

Not on your own record. However, if you are married to someone who worked 10 years and paid Medicare taxes, you can join Medicare at 62 based on their record. If you are under 65 and have no work history, you would need to look at Medicaid or marketplace insurance instead.

What if I worked in another country?

Work done outside the United States generally does not count toward Medicare, even if you paid taxes. However, some countries have agreements with the U.S. Social Security system. Contact Social Security to ask whether your work abroad can be credited. If not, you will need to count only U.S. work toward the 10-year requirement.

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

You can keep Medicare Part A (hospital insurance) if you move abroad, but Part B (medical insurance) coverage ends after you have been outside the U.S. for more than six months. If you return, you can restart Part B, but you may face a penalty if you did not have other coverage while you were away.

Can I get Medicare if I am still working at 65?

Yes. You can work and have Medicare at the same time. However, you still need to sign up during your enrollment window, even if you have employer coverage. If you delay signing up without a valid reason (such as current employer coverage), you may face a permanent penalty when you do enroll.

What happens if I do not sign up for Medicare when I turn 65?

If you do not have other health coverage and you miss your enrollment window, you will face a late enrollment penalty on your Part B premium for as long as you have Medicare. The penalty is 10 percent per year you were late. The only way to avoid it is to have had creditable coverage (like an employer plan) during the time you were not enrolled.
