Medicare does not cover spouses as dependents the way a family health plan does, but a spouse can still qualify for their own Medicare benefits based on the other spouse’s work history. If your husband or wife paid Medicare taxes for at least 10 years (40 Social Security work credits), you can get premium-free Part A once you turn 65, even if you never worked long enough to qualify on your own record.1Social Security Administration. Medicare Current spouses, divorced spouses, and surviving spouses each have a path in, with different rules about how long the marriage had to last.
How a Spouse Qualifies Through the Other’s Work Record
Medicare eligibility runs on Social Security work credits. You earn credits by working and paying Social Security and Medicare taxes, and credits stay on your record permanently.2Social Security Administration. How You Earn Credits Forty credits (about 10 years of covered work) unlocks premium-free Part A.
If you haven’t reached that on your own, you can draw on your spouse’s record instead. The working spouse doesn’t have to be enrolled in Medicare yet, and doesn’t have to be collecting Social Security. They just have to be eligible for Social Security or Railroad Retirement Board benefits.1Social Security Administration. Medicare
Part A is only the hospital-insurance piece: inpatient hospital stays, skilled nursing facility care, hospice, and some home health services.3Social Security Administration. Parts of Medicare Part B (doctor visits and outpatient care) still has its own monthly premium, and you enroll in it separately. The spousal work-record benefit is specifically that hospital coverage costs you nothing.
Eligibility for Current, Divorced, and Surviving Spouses
In every case, the spouse seeking Medicare must generally be at least 65. Younger people qualify only through a qualifying disability, end-stage renal disease, or ALS.4Medicare. Get Started With Medicare The other requirements depend on your marital status.
Current Spouses
If you’re married now, the marriage must have lasted at least one continuous year, and your spouse needs 40 work credits.5Social Security Administration. What Are the Marriage Requirements to Receive Social Security Spouses Benefits Once you turn 65, you can enroll in premium-free Part A on their record.
Divorced Spouses
A divorce doesn’t cut you off from your ex’s work record if three things are true:
- The marriage lasted at least 10 years.
- You are currently unmarried.
- Your ex-spouse is at least 62 and eligible for Social Security or Railroad Retirement Board benefits.
Your ex-spouse does not need to be collecting benefits, only eligible for them, and you do not need their permission or cooperation to apply.5Social Security Administration. What Are the Marriage Requirements to Receive Social Security Spouses Benefits
Surviving Spouses
If your spouse has died, you can qualify on their record at 65. You generally need to have been married for at least nine months before their death and be currently unmarried, or have remarried after age 60.
Watch out for a common mix-up: Social Security survivor benefits can begin as early as age 60 (or 50 with a disability), but Medicare eligibility still requires reaching 65 unless you qualify through disability, ESRD, or ALS.6HHS.gov. Who Is Eligible for Medicare Drawing survivor benefits at 62 does not put you on Medicare early.
If Neither of You Has 40 Credits
You can still enroll in Part A at 65 without 40 credits, but you’ll pay a monthly premium. For 2026:
- With 30 to 39 credits: $311 per month
- With fewer than 30 credits: $565 per month7Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles
A spouse’s credits help even when they don’t reach 40. If your spouse earned at least 30 credits, you get the reduced $311 rate on their record even if you personally have none.
If Your Spouse Is Under 65
This is where couples often assume Medicare will help and find out it won’t. Medicare has no dependent coverage and no spousal add-on. If you qualify at 65 but your husband or wife is younger, they cannot join Medicare on your enrollment. They have to wait until their own 65th birthday, or until they qualify through disability, ESRD, or ALS.
Until then, the younger spouse needs separate coverage. Options include staying on a working spouse’s employer plan, buying a plan through the Health Insurance Marketplace at healthcare.gov, or using COBRA continuation coverage from a previous employer (typically 18 to 36 months). Marketplace plans may come with premium tax credits based on household income.
If the older spouse is retiring and dropping employer coverage, that coverage ends for the younger spouse too. Losing job-based coverage triggers a Special Enrollment Period on the Marketplace, so the younger spouse can move directly to a Marketplace plan without waiting for open enrollment.
What the Qualifying Spouse Actually Gets
Once enrolled, a spouse receives the same Medicare benefits as anyone else. There is no reduced spousal version. You and your spouse each make your own coverage choices: one can stay on Original Medicare (Parts A and B, often with a Medigap policy) while the other picks a Medicare Advantage plan (Part C). Prescription drug coverage (Part D) is optional and purchased separately from a private insurer, unless it’s already bundled into an Advantage plan.8Medicare. Parts of Medicare

When to Enroll
Your first chance to sign up is the Initial Enrollment Period, a seven-month window that begins three months before the month you turn 65 and ends three months after your birthday month.10Medicare. When Can I Sign Up for Medicare Enrolling early in that window gets your coverage started sooner.
If you or your spouse are still working at 65 with employer group health coverage, you can delay Part B without penalty. When the employment or the group coverage ends (whichever comes first), an eight-month Special Enrollment Period opens for Part B.11Social Security Administration. Special Enrollment Period COBRA, retiree health plans, VA coverage, and Marketplace plans do not count as current employer coverage for this purpose. If you leave a job and switch to COBRA, the eight-month clock starts when the job-based coverage ended, not when COBRA runs out.12Social Security Administration. How to Apply for Medicare Part B During Your Special Enrollment Period
Missing your window matters. The Part B late enrollment penalty adds 10% to your monthly premium for every full 12 months you were eligible but didn’t enroll, and you pay that higher rate for as long as you have Part B.13Medicare. Avoid Late Enrollment Penalties Part D has its own permanent penalty if you go 63 or more consecutive days without creditable prescription drug coverage.
