Yes, you can get Medicare eligibility through your spouse’s work record. If your spouse has earned at least 40 work credits (about 10 years of paying Medicare taxes) and is at least 62, you can qualify for premium-free Part A once you turn 65, even if you never worked yourself. You don’t join your spouse’s plan the way you’d join their employer insurance. You get your own Medicare, with your own enrollment deadlines, your own premiums for Part B, and your own card.
Qualifying Through a Current Spouse
Three things have to be true for premium-free Part A on a current spouse’s record: you are at least 65, your spouse has 40 or more work credits, and you’ve been married for at least one year. Your spouse does not have to be collecting Social Security. They just have to be at least 62 and eligible for Social Security or Railroad Retirement benefits.
The age gap matters. If you turn 65 but your spouse is only 58, you can’t use their record yet. You’d either wait until they hit 62 or buy Part A in the meantime — $311 per month if you have 30 to 39 credits of your own, or $565 per month with fewer than 30 credits in 2026.1Centers for Medicare & Medicaid Services. Medicare Deductible, Coinsurance and Premium Rates for CY 2026
Without spousal eligibility or your own 40 credits, that Part A premium can reach $565 per month.2Centers for Medicare & Medicaid Services. 2026 Medicare Parts A & B Premiums and Deductibles Spousal eligibility lets you skip that cost entirely.
Qualifying Through a Divorced or Deceased Spouse
Marriage doesn’t have to be current. Divorced and surviving spouses can also qualify for premium-free Part A, with different rules for each.
Divorced Spouses
If your marriage lasted at least 10 years, you can qualify on your ex-spouse’s record once you turn 65. You must be currently unmarried, and your former spouse must be at least 62 and eligible for Social Security or Railroad Retirement benefits.3Social Security Administration. More Info – If You Had a Prior Marriage Your ex does not need to have filed for benefits, and their consent is not required. If you married the same person more than once across a 10-year span, the SSA can count those marriages together, as long as you remarried no later than the calendar year after the divorce became final.
Surviving Spouses
If your spouse has died, you can qualify on their record as long as your marriage lasted at least nine months before the death and your late spouse had earned enough work credits. You must be unmarried, or you must have remarried after age 60.4Social Security Administration. Who Can Get Survivor Benefits Surviving divorced spouses follow similar rules: at least 10 years of marriage, and either unmarried or remarried after 60.5Social Security Administration. Survivors Benefits
Special Marriage Situations
The SSA recognizes all legal marriages for Medicare purposes, but a few situations require extra documentation.
Same-sex marriages. Since the Supreme Court’s 2015 Obergefell decision, the SSA recognizes all legal same-sex marriages nationwide. The duration-of-marriage clock starts from the actual wedding date, not any court ruling.6Social Security Administration. Same-Sex Relationships – Spouse’s Benefits The same one-year, 10-year, and nine-month duration rules apply.
Common-law marriages. If your state recognizes common-law marriage, so does the SSA. You’ll need signed statements from both spouses (or the surviving spouse) plus statements from two blood relatives explaining why they believe a valid marriage exists.7Social Security Administration. Evidence of Common-Law Marriage Gathering those statements before you need them saves time at enrollment.
Non-citizen spouses. A non-citizen spouse can qualify through the working spouse’s record, but permanent residents must have lived continuously in the United States for at least five years before applying.8Centers for Medicare & Medicaid Services. Original Medicare (Part A and B) Eligibility and Enrollment You’ll need a Social Security number, a valid immigration document such as a green card, and proof of the marriage. The five-year clock can catch people off guard if they immigrated later in life.
When and How to Enroll
Even when you clearly qualify through your spouse, enrollment isn’t automatic. Missing your window can mean months without coverage and permanent premium penalties.
Initial Enrollment Period
Your Initial Enrollment Period is a seven-month window centered on the month you turn 65: three months before your birthday month, the birthday month itself, and three months after.9Medicare.gov. When Does Medicare Coverage Start Enrolling in this window is the cleanest path. No penalties, no gaps.
Special Enrollment Period
If you or your spouse still have employer-sponsored group health coverage when you turn 65, you can delay Medicare without penalty. Once that coverage or employment ends, you get an eight-month Special Enrollment Period to sign up for Part A and Part B.10Social Security Administration. Special Enrollment Period (SEP) The clock starts the month after the employment or group coverage ends, whichever comes first. COBRA and retiree health plans do not count as employer coverage for this purpose, so don’t rely on them to preserve your SEP.
General Enrollment Period
If you miss both windows, you can enroll between January 1 and March 31 each year, with coverage starting the month after you sign up.9Medicare.gov. When Does Medicare Coverage Start This is the safety net, and it comes with penalties.
How to Sign Up
Apply through the Social Security Administration online at ssa.gov, by calling 1-800-772-1213, or in person at your local Social Security office.11Social Security Administration.

Late Enrollment Penalties
These penalties are permanent additions to your monthly premiums, which is why enrollment timing matters so much.
- Part A: if you have to buy Part A because neither your work record nor your spouse’s qualifies you for premium-free coverage, and you don’t sign up when first eligible, your monthly premium increases by 10%. You pay that surcharge for twice the number of years you went without enrolling.13Medicare.gov. Avoid Late Enrollment Penalties
- Part B: for each full 12-month period you were eligible but didn’t enroll, your premium goes up by 10%. This one lasts as long as you have Part B.13Medicare.gov. Avoid Late Enrollment Penalties
- Part D: if you go 63 or more consecutive days without Part D or equivalent drug coverage, you’ll pay 1% of the national base beneficiary premium ($38.99 in 2026) for every uncovered month, recalculated annually and added to your Part D premium indefinitely.14Medicare.gov. How Much Does Medicare Drug Coverage Cost
To put numbers on it: someone who delayed Part B by three years without qualifying employer coverage would pay a 30% surcharge on every monthly premium going forward. At the 2026 standard premium of $202.90, that adds roughly $61 per month, over $700 a year, permanently.
What You’ll Still Pay in 2026
Qualifying through your spouse makes Part A free. The rest of Medicare still has costs, and everyone pays the same rates regardless of how they qualified.
Part B premium. $202.90 per month in 2026. Higher earners pay more through IRMAA surcharges once modified adjusted gross income exceeds $109,000 (individual) or $218,000 (joint), with premiums reaching $689.90 per month at the top bracket.2Centers for Medicare & Medicaid Services. 2026 Medicare Parts A & B Premiums and Deductibles The annual Part B deductible is $283.
Part A deductible. Premium-free doesn’t mean cost-free at the hospital. If you’re admitted, you owe $1,736 per benefit period in 2026.2Centers for Medicare & Medicaid Services. 2026 Medicare Parts A & B Premiums and Deductibles A benefit period resets after you’ve been out of a hospital or skilled nursing facility for 60 consecutive days, so multiple hospitalizations in a year could mean paying this deductible more than once.
Part D premium. Optional, varies by plan, and subject to its own IRMAA surcharges of $14.50 to $91.00 per month at the same income thresholds.2Centers for Medicare & Medicaid Services. 2026 Medicare Parts A & B Premiums and Deductibles
Coordinating With Your Spouse’s Employer Coverage
Many people who qualify through a spouse’s record are also on that spouse’s employer health plan. How the two plans interact depends on the size of the employer.
If the employer has 20 or more employees, the group health plan pays first and Medicare pays second. Delaying Part B until the employer coverage ends won’t trigger a penalty. If the employer has fewer than 20 employees, Medicare pays first and the group plan is secondary, so enroll in Part B when first eligible to avoid coverage gaps.15Centers for Medicare & Medicaid Services. MSP Employer Size Guidelines for GHP Arrangements – Part 1
One trap worth flagging: once you enroll in any part of Medicare, you can no longer contribute to a Health Savings Account. Because Part A can be backdated up to six months when you enroll after 65, anyone still contributing to an HSA should stop at least six months before Medicare enrollment to avoid a 6% excise tax on excess contributions. You can still spend existing HSA balances on qualified medical expenses, including Medicare premiums.
