Health Insurance in Divorce: The Cost Nobody Plans For
Most people spend months negotiating the house, the retirement accounts, and the investment portfolio. Almost nobody negotiates around health insurance — and then they discover what it costs, alone, in their late 50s or early 60s.
This is not a small oversight. Individual health insurance premiums vary significantly based on age, location, plan type, and income level. KFF (Kaiser Family Foundation) data shows that unsubsidized marketplace premiums for adults in their late 50s to early 60s can be substantially higher than premiums paid as dependents on an employer plan (KFF Health Insurance Marketplace Calculator; KFF.org, accessed 2025). The actual cost over the years between divorce and Medicare eligibility at 65 depends on individual circumstances and is for illustration only — it could be meaningfully higher or lower based on plan selection, geographic market, and whether income-based subsidies apply.
That number belongs in the divorce settlement conversation. Usually, it doesn't get there until after the settlement is signed.

Why Health Insurance Is a Divorce Financial Issue, Not Just a Benefits Issue
In most marriages, one spouse carries the family health insurance through an employer plan. The other spouse and any dependents are covered at a lower cost than if each bought individual coverage.
When the marriage ends, that coverage ends. Under federal COBRA rules, the departing spouse can continue on the employer plan for up to 36 months after losing coverage due to divorce — but they now pay the full premium, including the portion the employer was subsidizing (U.S. Department of Labor, "COBRA Continuation Coverage," DOL.gov, accessed 2025; 29 CFR Part 2590).
For many 55+ divorcing spouses, this produces sticker shock. A plan that cost $250/month as a dependent on a spouse's employer coverage suddenly costs $1,100–$1,400/month under COBRA. That is a real cash flow change that must be funded from somewhere — and it should be considered when dividing assets.

The Three Coverage Phases After Divorce
Understanding the options requires understanding the timeline from divorce to Medicare.
Phase 1: COBRA (Up to 36 Months)
COBRA (Consolidated Omnibus Budget Reconciliation Act) gives you the right to continue on your spouse's employer health plan for up to 36 months after losing coverage due to divorce. Election must be made within 60 days of receiving the COBRA election notice (U.S. Department of Labor, "COBRA Continuation Coverage," DOL.gov, accessed 2025; 29 CFR Part 2590).
What you pay under COBRA:The full premium — employer share plus employee share — plus up to 2% administrative fee. If your spouse's employer was covering a substantial portion of the premium, your out-of-pocket cost increases significantly.
Cost range:Premium costs under COBRA vary widely by employer plan, location, and coverage level. KFF's 2024 Employer Health Benefits Survey found that average annual premiums for employer-sponsored single coverage exceeded $8,900 in 2024 — the full amount of which the COBRA enrollee bears (KFF Employer Health Benefits Survey, 2024; KFF.org, accessed 2025). Actual costs depend on the specific plan.
When COBRA makes sense:When you're within three years of Medicare eligibility, or when you have a known health condition that makes underwriting on the individual market problematic. COBRA guarantees continuation of your current coverage without medical underwriting.
What to watch:COBRA is not indefinitely renewable. When 36 months expires, you transition to individual market coverage with no special protections unless you have a qualifying life event.
Phase 2: ACA Marketplace Plans
The Affordable Care Act marketplace (healthcare.gov) provides individual health insurance with guaranteed issue — meaning you cannot be denied coverage or charged more due to pre-existing conditions. Divorce is a qualifying life event that opens a 60-day special enrollment window outside of open enrollment.
Subsidies matter significantly.ACA subsidies are based on Modified Adjusted Gross Income (MAGI). If your divorce substantially reduces your income, you may qualify for premium tax credits that make marketplace coverage dramatically more affordable than COBRA.
A 60-year-old with annual income of $35,000 might pay $0–$200/month for a silver plan after subsidies. The same person with $90,000 in retirement income might pay $700–$1,000/month with no subsidy.
This interaction with retirement income planning is why sequencing matters.If you have flexibility in how you draw retirement income — from taxable accounts, pre-tax accounts, or Roth accounts — structuring withdrawals to keep MAGI below the subsidy cliff in the years before Medicare can save thousands annually.
What to watch:Marketplace plans vary significantly in network breadth, deductible levels, and out-of-pocket maximums. In some regions, marketplace plans have narrower networks than employer coverage. Verify your current doctors and hospitals are in-network before enrolling.
Phase 3: Medicare at 65
Medicare eligibility begins at 65. If you've worked and paid Medicare taxes for at least 10 years (40 quarters), you qualify for Medicare Part A (hospital) premium-free. Part B (outpatient) requires a monthly premium — currently around $185/month for most enrollees in 2025.
IRMAA surcharges:If your MAGI in the two years prior to Medicare enrollment exceeds certain thresholds, you pay higher Part B and Part D premiums through IRMAA (Income-Related Monthly Adjustment Amount). For 2025, IRMAA surcharges begin above $106,000 in MAGI for single filers (CMS, 2025 Medicare Cost Fact Sheet; CMS.gov, accessed 2025). These thresholds are adjusted annually by CMS. A large lump sum received in a settlement year may increase MAGI and affect Medicare premiums two years later.
Enrollment timing:If you're approaching 65, enroll during your Initial Enrollment Period (the 7-month window around your 65th birthday). Missing this window can result in permanent late enrollment premium surcharges for Part B and Part D (CMS, "Medicare and You," CMS.gov, accessed 2025). Medicare enrollment is not always automatic — individuals not already receiving Social Security benefits generally need to actively enroll.

What the Health Insurance Cost Should Mean for Your Settlement
If you were the dependent spouse on your ex's employer health plan, you are losing a benefit that had real financial value. That value should enter the settlement analysis.
Quantify the Coverage Gap
Step 1 is a specific number: what will you pay, monthly, for comparable health insurance from the date of divorce until age 65?
Walk through it:
- Years until Medicare eligibility: __ years
- Estimated monthly cost (COBRA first 3 years, then marketplace): $___/month
- Estimated 10-year total premium cost: $___
That number — often $60,000 to $130,000 — represents a cost the dependent spouse will bear that the insured spouse will not. It belongs in the asset division conversation, the alimony calculation, or both.
The "Just Get a Job" Problem
Courts and opposing attorneys sometimes dismiss health insurance concerns with "you can get a job with employer coverage." For someone 58–63 who has been out of the workforce for years, re-entering at a salary that comes with employer health benefits is not guaranteed — and may not happen on a timeline that eliminates the gap.
If re-employment is realistic, build it into the financial model with conservative assumptions. If it's not, be explicit about that in the settlement discussion.
Alimony and Health Insurance
Some divorce settlements address health insurance directly through alimony — with a premium reimbursement component or a higher monthly support amount to cover the known coverage cost. This can be cleaner than trying to add a fixed dollar amount to asset division, particularly when future health insurance costs are uncertain.
Under the TCJA tax rules (for divorces finalized after 2018), alimony is no longer deductible by the paying spouse or taxable to the receiving spouse. Whether to structure coverage costs as alimony or as asset division is a tax analysis question specific to your situation.

Health Insurance Considerations by Situation
If You're Under 60
You likely have the most flexibility. Marketplace coverage with subsidies may be affordable, particularly if your retirement income is structured to stay below the subsidy threshold. COBRA is a bridging option, but probably not your long-term solution. Getting employment with benefits is still realistic.
If You're 60–64
This is the most expensive window for individual health insurance coverage. You're old enough that actuarial pricing is high but not yet Medicare-eligible. COBRA can bridge if you're within 36 months of 65. Otherwise, the marketplace is your alternative — but subsidies phase out at higher income levels, and full-price coverage at this age is substantial.
Income management is critical here.If you can structure your income (portfolio withdrawals, Roth distributions, part-time work) to remain below the ACA subsidy threshold, you may reduce premiums dramatically for several years.
If You're 62–64 and Taking Early Social Security
Taking Social Security at 62 increases your MAGI and may reduce or eliminate your ACA subsidies. For people in the health insurance gap years, delaying Social Security — even to 65 — may save more in health insurance premiums than the Social Security delay earns. Model this interaction explicitly.
If You Have Pre-Existing Conditions
ACA marketplace plans must cover you regardless of health history. Under COBRA, you maintain continuous coverage without gaps that could cause complications. Do not have a gap in coverage that could later affect your ability to get care — though technically, under the ACA, gaps don't affect eligibility. What they can affect is your own comfort and continuity of care during transition.

What to Do Before Your Divorce Is Finalized
Get a specific cost estimate.Call a health insurance broker or usehealthcare.govto get actual premium quotes for your age and anticipated income level. Bring that number into the settlement conversation.
Understand COBRA deadlines.You have 60 days from receiving the election notice to elect COBRA. That notice may come weeks after the divorce is finalized. Don't wait.
Model your income for subsidy purposes.If you'll be using portfolio withdrawals for income, your advisor can help you structure draws to stay below ACA subsidy thresholds for the years before Medicare. This can save substantial money annually.
Build healthcare into the settlement.Whether through alimony, a specific asset transfer, or a reserve fund, make sure the settlement provides resources to cover what is often a 5–10 year healthcare gap.
Don't waive COBRA prematurely.Once you decline COBRA or let it lapse, you generally cannot re-elect it. Evaluate marketplace plans first, but don't forfeit your COBRA rights before you have a better option confirmed.

The Bottom Line
Health insurance is not a footnote in a divorce settlement for anyone over 55. For the spouse who loses employer coverage, it is a significant and quantifiable financial liability — one that belongs in the same conversation as the house, the retirement accounts, and the investment portfolio.
Getting specific numbers and building them into the settlement analysis is straightforward. Not doing so is one of the most expensive and most preventable mistakes divorcing spouses make.
A Certified Divorce Financial Analyst can help you quantify the coverage gap, model income scenarios that optimize for ACA subsidies, and make sure the settlement you sign actually accounts for what your financial life will cost.
