Retiring before 65 in Tennessee: bridging to Medicare

Retiring before 65 leaves a gap: you're out of employer coverage but not yet eligible for Medicare. In Tennessee, the marketplace at HealthCare.gov (1-800-318-2596) is the bridge most early retirees use — and retirement often lowers your income, which can make marketplace subsidies more generous than you'd expect.

Losing employer coverage may open a special enrollment period

Leaving your job and losing your employer health plan may qualify you for a marketplace special enrollment period — generally about 60 days around the qualifying event. Confirm your eligibility and exact dates at HealthCare.gov or 1-800-318-2596 rather than assuming.

COBRA can serve as a short bridge — it lets you keep your old employer plan — but it is typically expensive (you pay the full premium yourself) and time-limited to a set number of months. For many early retirees, COBRA covers the transition weeks while a marketplace application processes, not the whole multi-year gap.

Retirement often drops your income — recheck your subsidy

This is the single most valuable thing an early retiree can do. Premium tax credits are based on household income, and retirement frequently moves people into lower bands:

• For 2027, credits run from 100% to 400% FPL ($15,960–$63,840 single; $33,000–$132,000 family of four, under the 2026 guidelines), with a hard cliff at 400% — one dollar over means zero credit.
• Cost-sharing reductions (lower deductibles and copays) apply from 100–250% FPL on Silver plans only.
• Watch out for income that still counts: pension payments, 401(k) or IRA withdrawals, part-time work, and Social Security benefits can push you over the cliff. Plan withdrawals strategically and, as always, talk to a tax preparer — we don't give tax advice.

One caution: if your income drops below 100% FPL and you're a childless adult, you may fall into Tennessee's coverage gap — too low for marketplace subsidies, and Tennessee did not expand Medicaid. TennCare's categories (parents of children under 18 to 100% FPL, pregnant women to 250%, children in higher bands) still apply, but most childless adults won't qualify. It's worth a quick check at tenncareconnect.tn.gov, but keep your marketplace planning moving.

At 65: don't miss your Medicare Initial Enrollment Period

Your bridge has a hard end date. The Medicare Initial Enrollment Period is 7 months around your 65th birthday — the three months before, your birth month, and the three months after. Enrolling late can mean gaps in coverage and late penalties, so put it on the calendar now, not at 64 and 11 months.

Other Medicare windows to know:

• Annual Enrollment Period: October 15 – December 7, 2026 for 2027 coverage (effective January 1, 2027). For reviewing or changing Medicare Advantage and Part D plans.
• Medicare Advantage Open Enrollment: January 1 – March 31, 2027 — one plan change for people already in a Medicare Advantage plan.
• General Enrollment Period: January 1 – March 31 yearly, for those who missed earlier windows; late penalties may apply.

Note: Tennessee has no Medigap "birthday rule" (a bill was proposed but never enacted), so switching Medigap plans later can mean medical underwriting. Tennessee law does grant a 6-month guaranteed-issue Medigap window for people eligible for Medicare under 65, and federal law provides the standard 6-month Medigap open enrollment when you're 65+ and enrolled in Part B. We use 2026's Part B premium ($202.90) only as a labeled 2026 reference — the 2027 figure hasn't been announced.

Free Medicare counseling exists — use it

Tennessee SHIP (State Health Insurance Assistance Program) offers free, unbiased Medicare counseling: 1-877-801-0044. Use it before you pick a Medicare Advantage or Medigap plan. It's free, it's not selling anything, and the choices at 65 are genuinely confusing.

Frequently asked questions

Should I take COBRA or go straight to the marketplace?

COBRA keeps your current doctors and plan with zero disruption, but you pay the whole premium and it's time-limited. The marketplace may be far cheaper if your retirement income qualifies you for subsidies. Many people use COBRA for the first month or two while the marketplace application processes.

How do I estimate income when I'm retiring mid-year?

Estimate your total household income for the full coverage year — salary for the months you worked, plus pension, withdrawals, and any part-time earnings after. Update your HealthCare.gov application when the paychecks stop; your credit should adjust going forward.

What if my spouse is still working and I'm on their plan?

Then you may not need the marketplace at all — compare staying on the spouse's employer plan against a marketplace plan with your household income. Losing your own employer coverage while gaining a spouse's is a change worth running through HealthCare.gov's tools.

Can I get TennCare as an early retiree?

Only if you fit a category — most commonly a parent/caretaker relative of a child under 18 at or below 100% FPL. Most childless early retirees won't qualify; that's Tennessee's coverage gap, and we'd rather say so plainly than waste your time.

When should I start planning for Medicare?

A year before you turn 65. Call Tennessee SHIP at 1-877-801-0044, learn the parts (A, B, D, Advantage, Medigap), and mark your 7-month Initial Enrollment Period on the calendar.

Your next step

1. Confirm your special enrollment window at HealthCare.gov or 1-800-318-2596 after your employer coverage ends — generally about 60 days, so don't drift.
2. Estimate your post-retirement household income (pension, withdrawals, part-time work, spouse's income) and run it through HealthCare.gov's plan preview to see your subsidy.
3. Compare COBRA vs. marketplace on total cost for your situation — COBRA as a possible short bridge, marketplace as the multi-year solution.
4. Twelve months before you turn 65, call Tennessee SHIP (1-877-801-0044) for free Medicare counseling, and mark your 7-month Initial Enrollment Period.
5. Talk to a tax preparer about how retirement-account withdrawals interact with premium tax credits — the 400% FPL cliff makes this planning matter.
