Medicare Eligibility Checker
A quick, educational read on Medicare eligibility based on age, work history, and citizenship status.
How the checker works
This educational tool compares age, Medicare-taxed work history, and citizenship or residency status with common Medicare eligibility guidelines. It uses those answers to provide a likely result, including whether premium-free Part A may be available.
Use the result as a starting point for gathering records and questions before confirming your situation with Medicare or Social Security.

Likely Eligible for Premium-Free Part A
Based on age 65+ and at least 10 years (40 quarters) of Medicare-taxed work history, this person is likely eligible for premium-free Medicare Part A, plus the option to enroll in Part B.
Educational Only: This tool does not determine actual Medicare eligibility. Confirm your status directly with Medicare.gov or the Social Security Administration.

What the result means
- Likely eligible for premium-free Part A: Your parent (or their spouse) paid Medicare taxes for about 10 years (40 quarters). Part A, which covers hospital stays, won’t have a monthly premium. Part B still has a premium ($202.90/month standard in 2026).
- Eligible, but may pay for Part A: With fewer than 40 quarters, Part A can still be bought. In 2026 the premium is $311/month with 30–39 quarters and $565/month with fewer than 30.
- Not yet eligible: Most people become eligible at 65. Some qualify earlier through Social Security disability or certain conditions. Contact Social Security to check.
When to sign up
- Initial Enrollment Period: A 7-month window that starts 3 months before the month your parent turns 65 and ends 3 months after.
- If they’re still working with employer coverage: They may be able to delay Part B without a penalty and use a Special Enrollment Period later. Check with the employer’s benefits office first.
- Late penalty: Signing up for Part B late without qualifying coverage can mean a 10% higher premium for each 12 months they could have had it, for as long as they have Part B.
- Every fall: Once enrolled, your parent can change plans during Open Enrollment, October 15–December 7. See our Medicare Open Enrollment guide.
A worked example
Your dad turns 65 in March. He worked 30 years and paid Medicare taxes the whole time. His Initial Enrollment Period runs December through June. He’s likely eligible for premium-free Part A, and he’ll pay the standard Part B premium unless his income is high enough to trigger a surcharge.
What to have ready
- Social Security number and birth certificate
- Dates of employment and any current employer or union coverage
- Spouse's work history (it can count toward premium-free Part A)
- A list of doctors and prescriptions, for choosing a plan

Frequently Asked Questions
Does this checker determine official Medicare eligibility?
No. It provides an educational first look based on the details entered. Confirm eligibility, enrollment timing, and costs with Medicare.gov or the Social Security Administration.
Why does the checker ask about 10 years of work history?
Medicare generally uses 40 quarters, or about 10 years, of Medicare-taxed work to determine eligibility for premium-free Part A. A spouse's work history may also count in some situations.
Can someone qualify for Medicare before age 65?
Some people qualify before 65 through certain disability or End-Stage Renal Disease provisions. This simple checker does not evaluate those pathways, so contact the Social Security Administration for guidance.
Can my parent get Medicare based on my other parent's work record?
Yes, a spouse's work history can count toward premium-free Part A in many cases, including some divorced and widowed spouses. Social Security can confirm.
Does my parent have to sign up if they're already getting Social Security?
People already getting Social Security benefits are usually enrolled in Parts A and B automatically at 65 and get a card in the mail. Others need to sign up through Social Security.
