Health Insurance Before Medicare: Your Options Before 65

The problem: a coverage gap before Medicare

Medicare eligibility starts at age 65. Retire before that and your employer coverage usually ends within a month or two — leaving a stretch of a few months to a few years with no plan. Going uninsured is a gamble most near-retirees can't afford: one hospital stay can undo years of saving. The good news is you have four realistic ways to bridge the gap, and for many early retirees one of them is surprisingly affordable.

Option 1: The ACA marketplace (often the cheapest)

Marketplace plans at HealthCare.gov (or your state exchange) can't turn you down or charge more for pre-existing conditions, and premium tax credits are tied to your income — not your assets. That's the quirk that helps retirees: a couple living partly off savings can show a modest taxable income and qualify for a large subsidy, even with a healthy nest egg. Losing job-based coverage triggers a 60-day special enrollment period, so you don't have to wait for open enrollment.

For 2026, subsidies are calculated against the 2025 federal poverty guidelines. Below the 400% line, your benchmark Silver premium is capped at a share of income that rises to just under 10%; above it, you pay full price. That makes 400% of poverty — about $62,600 for one person and $84,600 for a couple in the 48 states and DC — the single most important number to plan around. Alaska and Hawaii run on their own, higher poverty guidelines, so their cliffs sit further out: about $78,200 for one person and $105,720 for a couple in Alaska, and $71,960 and $97,280 in Hawaii. Those are the lines for 2026 coverage. The Marketplace switches to the 2026 poverty guidelines when enrollment for 2027 opens on November 1, and the cliff moves up to about $63,840 for one person and $86,560 for a couple.

Option 2: COBRA (keep your current plan — at full cost)

COBRA lets you keep your existing employer plan — same doctors, same network — typically for up to 18 months after you leave. The catch: you pay the entire premium (your share plus what your employer used to cover) plus up to a 2% administrative fee, which often lands around $650–$900+ a month per person — you now pay the entire employer-plan premium yourself, which the KFF Employer Health Benefits Survey puts near that range for single coverage nationally. COBRA makes the most sense if you're mid-treatment, want to keep a specific doctor, or only need to bridge a few months before Medicare or a spouse's open enrollment.

Option 3: A spouse's employer plan

If your spouse is still working and their employer offers coverage, your retirement is usually a qualifying life event that lets you join their plan within 30 days — no need to wait for their open enrollment. This is frequently the cheapest option of all when it's available, because the employer is still subsidizing the premium. Compare the added cost of family coverage against a marketplace plan before deciding.

Option 4: Part-time work with benefits

Some employers — notably Starbucks, Costco, UPS, and many hospitals and universities — offer health benefits to part-time staff. A bridge job for the last year or two before Medicare can cover both your premiums and some of your expenses, while keeping you socially engaged. Confirm the minimum weekly hours required for benefits before counting on it.

Which health insurance is cheapest before Medicare?

Don't compare monthly premiums alone — compare what you'll actually spend across a full year:

• Premium after any subsidy × 12 (marketplace subsidies can flip the ranking entirely).
• Deductible and out-of-pocket max — a cheaper premium with a $9,000 deductible may cost more if you use care.
• Your doctors and prescriptions — confirm they're in-network on each plan.
• How many months you need it — COBRA's 18-month limit and your 65th birthday both set hard deadlines.

The mistake that costs the most: blowing your subsidy

Because 2026 subsidies vanish the moment you cross 400% of poverty, a well-meaning money move can backfire. A large Roth conversion, a big capital gain, or an IRA withdrawal in the same year all raise your MAGI — and pushing it one dollar over the cliff can cost you thousands in lost premium tax credits. If you're buying on the marketplace, coordinate those moves carefully (or spread them across years). Confirm your projected MAGI against the cliff in the calculator before you pull any large sum.
