FEHB in Retirement: Federal Employee Health Insurance After You Leave

Federal employees have one of the most valuable retirement benefits in America: the ability to carry FEHB (Federal Employees Health Benefits) into retirement with the government still paying about 72% of the premium. But at age 65, the Medicare coordination decision changes the picture — and the interaction with your pension income adds another layer most federal employees don't anticipate.

The FEHB advantage: government still pays ~72% in retirement

Most private-sector retirees lose employer health coverage the day they leave. Federal retirees don't. OPM continues to pay the government's share of FEHB premiums — the same formula that applies to active employees:¹

• The government pays the lesser of (a) 72% of the weighted-average premium across all plans for your enrollment type, or (b) 75% of your specific plan's total premium.
• For 2026, the maximum government biweekly contribution is $324.76 (Self Only), $711.17 (Self Plus One), and $778.03 (Self and Family).²

In retirement, FEHB premiums are deducted monthly from your annuity check rather than from a paycheck biweekly. OPM handles the deduction automatically once your retirement paperwork is processed.

The 5-year rule: the prerequisite most employees don't check until it's too late

To carry FEHB into retirement, you must have been continuously enrolled (or covered as a family member) in FEHB for the 5 years immediately before retirement — or since your first eligible opportunity if you've been federal less than 5 years.¹

What breaks the 5-year clock:

• Voluntarily canceling FEHB enrollment (e.g., moving to a spouse's private-sector plan)
• A break in federal service where you were not covered

What does NOT restart the clock:

• Changing plans during Open Season (stays continuous)
• Adding or removing family members
• A gap caused by a break in service if coverage resumed when you returned

Tactical tip: if you re-enrolled recently

If you canceled FEHB and re-enrolled (e.g., you were on a spouse's plan for several years), your 5-year clock restarts from re-enrollment. If you're 4 years and 8 months from your planned retirement, you may need to delay retirement by a few months to satisfy the 5-year requirement. This is worth a call to your agency's HR office to confirm your exact continuous-enrollment date.

At retirement: nothing changes (yet)

Before age 65, retirement FEHB works almost identically to active-employee FEHB. You keep your same plan, your same premium formula, and your same coverage network. The only operational difference is the monthly-vs-biweekly deduction rhythm.

FERS employees who retire before 62 are still receiving the FERS Supplement as a bridge. Be aware that if the Supplement stops (at 62 or due to the earnings test), your net monthly income drops and you'll be paying FEHB premiums from your smaller base annuity alone.

The Medicare decision at 65: the most consequential FEHB choice

At age 65, you become eligible for Medicare. Federal retirees under FERS (hired after January 1, 1984) paid Medicare payroll taxes throughout their careers and qualify for premium-free Medicare Part A. CSRS employees hired before 1984 may not have paid Medicare taxes during their early years — some have to pay for Part A ($278/month in 2026 if fewer than 30 quarters of covered work).³

Medicare Part A (hospital) is free or nearly free for most federal retirees. The decision is primarily about Medicare Part B (outpatient/physician).

Option 1: FEHB + Medicare Part A + Part B (the wraparound)

If you enroll in Medicare Part B, Medicare becomes the primary payer and FEHB becomes the secondary payer for services covered by both. The practical result:

• Medicare pays its share first (e.g., 80% of approved charges after deductible)
• FEHB pays most or all of the remaining 20%, plus the deductible
• Your out-of-pocket costs for covered services often drop to near zero
• Many FEHB plans waive the Part B deductible ($283 in 2026³) and cost-share for enrollees who have Part B

The cost of this arrangement is the Part B premium: $202.90/month in 2026 ($2,434.80/year) at the standard rate.³ Higher-income retirees pay more under the IRMAA surcharge — pension income and IRA distributions both count toward the MAGI test.

Option 2: FEHB only, no Part B enrollment

You are not required to enroll in Part B. Choosing to keep FEHB as your sole coverage means:

• No $202.90/month Part B premium
• FEHB remains the primary payer — you face the plan's normal deductibles, copays, and out-of-pocket maximums
• For retirees with rare or no healthcare usage, this can be lower cost than FEHB + Part B
• If you later want Part B, you'll face a 10% late-enrollment penalty for every 12-month period you delayed, plus a gap in coverage until the next General Enrollment Period (January–March, with coverage starting July 1)

Most financial planners recommend enrolling in Part B when you first become eligible. The late-enrollment penalty is permanent; it compounds across a long retirement. The break-even on the Part B premium vs. the wraparound benefit usually favors enrollment within 2–4 years of eligibility.

Option 3: Suspend FEHB for Medicare Advantage

If you enroll in a Medicare Advantage (Part C) plan, you can suspend your FEHB enrollment.⁴ Suspension is different from cancellation:

FEHB cost in retirement: what to expect

Annual FEHB premiums vary widely across the roughly 200+ plans available to federal employees. The government's contribution cap (above) means that for mid-to-higher-premium plans, you pay the difference. A representative range for 2026:

Use OPM's FEHB Plan Comparison Tool for exact 2026 premiums by ZIP code and plan type.

If you add Medicare Part B ($202.90/month = $2,434.80/year base), your total healthcare cost including both premiums might be $3,000–$5,000/year — comparable to a comprehensive private-sector retiree healthcare package, but with near-zero out-of-pocket once both payers coordinate.

How pension income affects FEHB affordability

FEHB premiums are automatically deducted from your monthly annuity check. This is a fixed obligation before you see any money. For FERS retirees with modest annuities (e.g., $2,200/month after survivor reduction), a Self Plus One premium of $200–$400/month is a material drag.

For FERS employees with a TSP balance, this is one reason the TSP-vs-rollover decision matters: keeping substantial savings in a tax-deferred account lets you supplement pension income for healthcare costs without immediately recognizing income (potentially managing IRMAA exposure if Roth conversions are timed correctly).

For CSRS retirees with higher pensions (often $4,000–$6,000+/month), FEHB premiums are a smaller share of income, and the optimization shifts to the IRMAA question: at those income levels, Part B IRMAA surcharges can add $500–$1,500/year above the base premium.

Survivor protection: FEHB after the annuitant dies

A surviving spouse can continue FEHB in retirement only if both of the following are true:⁴

1. The annuitant was enrolled in Self Plus One or Self and Family at the time of death (Self Only does not cover a surviving spouse)
2. A monthly survivor annuity is payable to the spouse (i.e., the annuitant elected partial or full survivor benefit at retirement, or the Basic Employee Death Benefit applies)

If no survivor annuity is payable, the surviving family member is entitled only to Temporary Continuation of Coverage (TCC): a free 31-day extension, followed by up to 18 months at the full unsubsidized premium plus 2%. There is no government contribution during TCC.

Decision checklist: FEHB in retirement

FEHB, pension income, and a fee-only advisor

The FEHB decision doesn't live in isolation. It intersects with:

• Pension survivor election — which determines FEHB coverage for your spouse after you die
• TSP rollover timing — large distributions trigger IRMAA surcharges 2 years later (the SSA "lookback" uses MAGI from 2 years prior)
• Roth conversion strategy — converting TSP or IRA funds to Roth reduces future RMDs but adds to current-year income that affects Part B IRMAA tiers
• FERS Supplement end-date — at 62, your net income drops by the supplement amount; model whether FEHB premiums remain affordable from annuity alone

A fee-only advisor who specializes in federal employee retirement can model all of these interactions together — not just the pension decision in isolation. Most commission-based advisors focus on the TSP rollover (which earns them AUM fees) without addressing the healthcare cost structure at all.
