Divorced over 65 in 2026 is a different problem from divorced at 40. Medicare belongs to you personally, so Part A, Part B, a Medicare Advantage plan, a Medigap policy, and a Part D drug plan all stay in force after the decree. What changes is everything layered on top of Medicare: the employer plan your ex-spouse carried for you, the Social Security benefit you may now claim on your ex-spouse's record, the income that sets your IRMAA surcharge, and the household income that decides whether you qualify for a Medicare Savings Program. Each of those has its own rule, and each runs on a different clock. The Part B Special Enrollment Period is 8 months. The Medigap guaranteed-issue window and the Part D creditable-coverage gap are 63 days. The Marketplace SEP is 60 days, but it matters only for people without premium-free Part A. Divorced spouse benefits have no filing deadline, yet every month of delay can reduce what you collect. This page lays out the order of operations so the decisions with the shortest clocks come first, using 2026 figures from medicare.gov, ssa.gov, and cms.gov.
Most divorces after 65 fall into one of three situations, and the right first move depends on which one you are in. In the first, you already have Parts A and B and a separate drug plan, so little changes beyond income and filing status. In the second, you are 65 or older but never enrolled in Part B because you were covered by your ex-spouse's active employer plan, so the divorce is a qualifying life event that starts the 8-month Part B Special Enrollment Period. In the third, you are 65 or older with a thin work history and rely on an ex-spouse's record for premium-free Part A. Marketplace plans and COBRA are poor fits at this age because both can conflict with Medicare, and Form 1095-A reconciliation becomes a tax problem if a subsidized Marketplace plan overlaps with Medicare. The steps below, the options table, and the document checklist cover all three situations, along with the Medi-Cal, MassHealth, and other state Medicaid routes that open when divorce drops your income in 2026.
6 Steps to Get Coverage
Common Mistakes That Cost People Thousands
Divorced Medicare beneficiaries over 65 lose the most money through five avoidable errors, most of them tied to the wrong assumption that group coverage and COBRA work the way they do for younger people.
- Electing COBRA instead of enrolling in Part B. COBRA does not start the Part B Special Enrollment Period clock, so the 8-month window can expire while you pay 102% of the premium and the 10% per year Part B penalty keeps growing.
- Missing the 63-day Medigap window. After the guaranteed-issue period ends, insurers in most states can use medical underwriting to deny you or raise your 2026 premium.
- Remarrying before claiming a divorced spouse benefit. Remarriage ends eligibility for the benefit on your ex-spouse's record, so check the timing with Social Security before the wedding.
- Ignoring the IRMAA appeal. Your 2026 surcharge is based on your 2024 tax return, which often reflects joint income, and Form SSA-44 is the only way to use your lower post-divorce income.
- Keeping a subsidized Marketplace plan after Part A starts. Premium tax credits stop when you are entitled to premium-free Part A, and the overpaid credits appear on Form 1095-A reconciliation as a tax bill.
Divorced Spouse Benefits and Premium-Free Part A on an Ex-Spouse's Record in 2026
Social Security pays a divorced spouse benefit of up to 50% of your ex-spouse's full retirement amount when four conditions are met: your marriage lasted at least 10 years, you are at least 62, you are currently unmarried, and your own retirement benefit is smaller than the divorced spouse benefit. If you have been divorced for 2 years or more, your ex-spouse does not need to have filed for benefits yet, as long as your ex-spouse is old enough to qualify. Claiming before your full retirement age, which is 66 to 67 depending on birth year, permanently reduces the benefit, and the benefit never reduces what your ex-spouse or your ex-spouse's new spouse receives. The same 10-year marriage rule opens premium-free Part A at 65 on your ex-spouse's work record, which matters most if you have fewer than 40 work credits of your own. Without either route, Part A premiums can run well above the 2026 Part B figure of $202.90/mo, so confirm eligibility at ssa.gov or by calling 1-800-772-1213 before buying Part A. Apply as soon as the decree is final, because Social Security reviews marriage dates and work records manually and the process can take weeks.
Part B Special Enrollment Period After Losing an Ex-Spouse's Group Plan in 2026
Medicare Part B offers an 8-month Special Enrollment Period when you were covered by a group health plan based on current employment, either your own or a spouse's, and that coverage ends. Divorce ends your status as a spouse, so the ex-spouse's employer plan stops covering you on the date the plan sets, often the last day of the month of the decree. In 2026, Part B costs $202.90/mo with a $283 annual deductible, and enrolling inside the window avoids the 10% late penalty for each full 12 months of delay. Retiree coverage, COBRA, and individual Marketplace plans do not qualify you for this SEP, which is why many divorced people over 65 wrongly believe they have more time than they do. Part B coverage starts the first of the month after you enroll in the SEP, so apply while the old plan is still active to avoid a gap. Medicare Advantage and Part D have their own short Special Enrollment Periods after involuntary loss of creditable coverage, and a Part D gap of 63 days or more without creditable drug coverage adds a late penalty of 1% of the $38.99 national base premium for 2026 for every month, permanently.
IRMAA Appeal After Divorce in 2026 With Form SSA-44
IRMAA, the Income-Related Monthly Adjustment Amount, adds a surcharge to Part B and Part D premiums for 2026 when the modified adjusted gross income on your 2024 tax return exceeds $109,000 for a single filer or $218,000 for a joint filer. A couple that filed jointly in 2024 can show combined income above the joint threshold, and the surcharge then follows the newly divorced person even though half of that income is gone. Divorce is a listed life-changing event on Form SSA-44, which lets Social Security set the surcharge from a more recent tax year or an estimate of your current income instead. Submit the form with the final divorce decree and, if your income also dropped for other reasons, documents such as a pension statement or a settlement agreement showing the income split. Social Security typically decides within 30 to 60 days, and a successful appeal is applied back to the start of the year the event occurred. Medicare Savings Programs in your state also look at income, so a lower IRMAA bracket and a Medicaid application often work together after a divorce.
Medicaid and Medicare Savings Programs After a Divorce in 2026
Medicaid and Medicare Savings Programs often become available after a divorce at 65 or older because the household shrinks to one person and income falls. Federal income benchmarks tie to the 2026 Federal Poverty Level of $15,960 for one person, and the Medicare Savings Programs (QMB, SLMB, and QI) pay some or all of the $202.90/mo Part B premium, with Qualified Medicare Beneficiary status also covering Part A and Part B deductibles and coinsurance. Extra Help lowers Part D costs when income is under 150% of the Federal Poverty Level, and the 2026 Part D out-of-pocket cap is $2,100. State Medicaid programs go by different names: California's Medi-Cal, Arizona's AHCCCS, Massachusetts's MassHealth, Wisconsin's BadgerCare, Tennessee's TennCare, Oregon's OHP, and Washington's Apple Health. People 65 and older are assessed under aged, blind, and disabled rules rather than the 138% FPL expansion test, and many states also count assets, so a divorce settlement that moves savings into your name can change the result. Apply through your state Medicaid agency or at medicaid.gov, and note that children or grandchildren still in your care may qualify for CHIP separately.
Frequently Asked Questions
What is the Special Enrollment Period for Medicare after a divorce at 65 or older?
The Medicare Part B Special Enrollment Period lasts 8 months after your group health coverage based on current employment ends. If your ex-spouse's employer plan ends November 30, 2026, your window runs December 1, 2026 through July 31, 2027. Two shorter clocks run alongside it: 63 days for guaranteed-issue Medigap and to avoid a Part D late penalty, and 60 days for a Marketplace SEP if you are not entitled to premium-free Part A. Divorce itself is a qualifying life event, but the clock starts when coverage ends, not on the decree date. Confirm the exact end date with the plan administrator, then enroll at ssa.gov or call 1-800-772-1213.
How do I document my divorce for Medicare and Social Security?
Divorced Medicare applicants need the final divorce decree, the marriage certificate, and a notice from the ex-spouse's employer giving the date group coverage ended. For Part B, the employer or plan must also complete Form CMS-L564 (Request for Employment Information) to confirm the coverage was based on current employment. For a divorced spouse benefit, Social Security needs your ex-spouse's Social Security number or full name, date of birth, and place of birth. For an IRMAA appeal, attach the decree to Form SSA-44. Keep copies of everything, because Medicare, Social Security, and your state Medicaid agency each ask for the same papers separately.
What happens if I miss the Part B Special Enrollment Period after my divorce?
Missing the 8-month Part B window means you can enroll only during the General Enrollment Period, January 1 through March 31 each year, with coverage starting the month after you sign up. Part B then adds a 10% penalty for every full 12 months you were eligible but not enrolled, and the penalty lasts for life on top of the 2026 base premium of $202.90/mo. A missed Part D window adds 1% of the $38.99 national base premium for 2026 for each uncovered month. Medigap guaranteed issue also expires after 63 days in most states, so a late applicant can be denied or charged more.
Can I get retroactive coverage or retroactive benefits after a divorce?
Medicare Part B through the Special Enrollment Period is not retroactive: coverage starts the first day of the month after you enroll, so apply before group coverage ends to prevent a gap. Social Security may pay up to 6 months of retroactive divorced spouse benefits once you have reached full retirement age, but benefits are never retroactive to a date before you reached that age, so ask the claims representative about your exact start date. Medicaid in many states can reach back up to 3 months before your application month if you were eligible, so keep medical bills from the weeks after the divorce.
What is the difference between COBRA, Marketplace coverage, and Medicare after divorce at 65?
COBRA keeps your ex-spouse's employer plan for up to 36 months at 102% of the full premium, but it ends when you become entitled to Medicare and does not qualify you for the Part B Special Enrollment Period. A Marketplace plan at healthcare.gov offers a 60-day SEP, but premium tax credits stop once you are entitled to premium-free Part A, and Form 1095-A reconciliation can create a tax bill for overlapping months. Medicare, with Part B at $202.90/mo in 2026 plus Medigap or Medicare Advantage and Part D, is the standard path for people 65 and older. Use COBRA only as a short bridge.
What state-specific rules apply to Medicare and Medigap after a divorce?
Medicare Part A, Part B, and Part D rules are federal and identical in all 50 states. State rules matter for Medigap and Medicaid. Connecticut and New York offer year-round Medigap guaranteed issue, while California and several other states give a birthday-based window to switch Medigap plans without underwriting. Medicaid and Medicare Savings Program rules also vary by state brand: Medi-Cal in California, AHCCCS in Arizona, MassHealth in Massachusetts, and BadgerCare in Wisconsin each set their own income and asset tests for people 65 and older. Check your state insurance department for Medigap rules and your state Medicaid agency for savings-program limits.
Do I qualify for Medicaid or a Medicare Savings Program after my divorce?
Medicaid for people 65 and older uses aged, blind, and disabled rules, not the 138% FPL expansion test that equals $22,025 for one person in 2026. Medicare Savings Programs pay your $202.90/mo Part B premium if income and countable resources fall under your state's limits, and Extra Help lowers Part D costs when income is under 150% of the 2026 Federal Poverty Level of $15,960. A divorce that splits a joint income in half often moves one person under these lines. Apply through your state Medicaid agency, such as Medi-Cal or MassHealth, and check the household-size table on this page for the 2026 benchmarks.
What happens to my children's or dependents' coverage after a divorce at 65 or older?
Children or grandchildren in your care lose coverage under an ex-spouse's employer plan only if the plan drops them, and a parent's divorce alone does not usually end a child's coverage under the other parent's plan. If a dependent child loses coverage, a 60-day Marketplace SEP opens at healthcare.gov, and CHIP or Medicaid are available year-round when household income qualifies. Medicare does not cover dependents, so a spouse or child under 65 cannot join your Medicare. Ask the plan administrator in writing whether each dependent keeps coverage, and apply for CHIP through your state agency if income is low.
