Federal Retirement Health Insurance: How FEHB Works After You Leave Service

The Two Requirements for Keeping FEHB After Retirement

Federal employees don't automatically keep their health insurance when they retire. Two statutory conditions must be met, and failing either one means permanent loss of FEHB eligibility:

Condition 1 — Immediate annuity. You must retire on an immediate civilian annuity — one that begins accruing within one month of your separation date. Under FERS, the standard paths are MRA with 30 years of service, age 60 with 20 years, or age 62 with 5 years. An MRA+10 retirement also qualifies, though it comes with a 5% pension reduction for each year under age 62.

If you separate and elect a deferred retirement (waiting until you reach a qualifying age to start receiving your pension), you forfeit FEHB permanently. A postponed retirement under MRA+10 rules is different — you can delay receiving annuity payments to avoid the age penalty, and you'll regain FEHB access once your annuity begins.

Condition 2 — Five consecutive years of FEHB enrollment. You must have been enrolled in FEHB (or covered as a family member under someone else's FEHB) for the five years immediately before your retirement date. If you've been eligible for less than five years, you must have been enrolled for your entire period of eligibility since first becoming able to enroll.

Switching plans during Open Season doesn't break continuity. Changing from Self and Family to Self Only doesn't break it either. What does break it: voluntarily canceling your FEHB enrollment while still employed. If you cancel, the five-year clock resets completely and all prior enrollment time is forfeit.

What FEHB Costs in Retirement

The government continues to pay approximately 72% to 75% of the weighted average premium, the same formula used for active employees. The difference is how premiums are collected: instead of payroll deductions, OPM withholds your share from your monthly annuity payment.

During the interim pay period — typically the first 2 to 4 months after retirement while OPM processes your claim — no health insurance premiums are deducted from your interim payments. OPM collects those retroactively once your claim is finalized. Budget for that lump-sum retroactive deduction so it doesn't surprise you.

You can change FEHB plans during annual Open Season (mid-November through mid-December), just as you could while working. Retirees use OPM's Services Online portal to make changes, not the agency HR systems they used during active service.

What Happens at Age 65

Reaching 65 adds a new layer: Medicare eligibility. This doesn't change your FEHB coverage — your plan continues regardless. But it introduces a financial calculation about whether to add Medicare Part B alongside FEHB.

Medicare Part A is premium-free if you have 40+ quarters of Social Security-covered earnings. Most federal employees qualify, even those under CSRS who had some Social Security-covered employment. Part A covers inpatient hospital stays, and your FEHB plan coordinates as secondary coverage, typically paying the Medicare hospital deductible ($1,736 in 2026).

Medicare Part B costs $202.90 per month at the standard rate (2026) and covers outpatient medical services. When Part B is primary and FEHB is secondary, most major FEHB plans waive their deductibles, copayments, and coinsurance entirely. That wrap-around benefit can reduce out-of-pocket medical costs to near zero — but you're paying $2,434.80 per year in Part B premiums for it.

If you were still working past 65, your FEHB plan was primary and Medicare secondary. Once you retire, the payer order flips: Medicare becomes primary, FEHB becomes secondary. This happens automatically.

FEHB Enrollment Options for Retirees

Retirees have the same plan tier options as active employees:

• Self Only — covers the annuitant
• Self Plus One — covers the annuitant and one eligible family member
• Self and Family — covers the annuitant and all eligible family members

Your FEHB enrollment tier matters for survivor coverage. If you want your spouse to continue FEHB after your death, you must be enrolled in Self Plus One or Self and Family at the time of death, and your spouse must be receiving a survivor annuity (25% or 50% of your unreduced pension under FERS). Without both conditions met, your spouse's FEHB coverage ends permanently when you die.

VERA, VSIP, and the Five-Year Rule Waiver

Employees who retire under Voluntary Early Retirement Authority (VERA) or accept a Voluntary Separation Incentive Payment (VSIP) buyout get a pre-approved waiver of the five-year rule. The agency's HR department attaches a waiver memorandum to your retirement package sent to OPM.

This waiver only applies to agency-authorized VERA/VSIP windows. If you're voluntarily retiring without VERA/VSIP authorization and don't have five years of continuous FEHB enrollment, you're out of options — OPM rarely grants individual waivers for standard voluntary retirements.

Premium Deductions and Tax Treatment

FEHB premiums for retirees are deducted from your gross annuity before federal income tax withholding, which means they're effectively paid with pre-tax dollars. This is the same tax treatment as the employee premium share during active service.

If you're receiving a CSRS annuity, your FEHB premiums are fully pre-tax. FERS retirees receiving a combination of annuity and Social Security have their FEHB premiums deducted only from the annuity portion.

State tax treatment varies. Some states fully exempt federal pensions from state income tax; in those states, the FEHB premium deduction provides no additional state tax benefit because the income wasn't taxed at the state level anyway.

What to Verify Before You File

Before submitting your retirement application, pull your SF-50 history from your Electronic Official Personnel Folder (eOPF) and verify continuous FEHB enrollment for the five years before your planned retirement date. Look for any periods of canceled coverage, LWOP without FEHB, or gaps between appointments.

TRICARE time can count toward the five-year requirement, as long as you're actively enrolled in FEHB on your exact retirement date.

The FEHB & Medicare Coordination Guide includes a complete eOPF audit worksheet and a pre-retirement verification checklist that maps every step from the five-year rule through your Medicare enrollment windows.
