FEHB in retirement: keeping your federal health benefits for life

FEHB does not end when your federal career does. If you meet the eligibility rules, you can keep the same comprehensive coverage in retirement that you had while working, with the government continuing to pay approximately 72% of the weighted average premium. The catch is that a single gap in the last 5 years, or the wrong kind of retirement, can cost you the benefit permanently.

Keeping FEHB in retirement

Federal Employees Health Benefits (FEHB) is often the single most valuable benefit a federal employee carries into retirement. Unlike most private-sector retiree coverage, FEHB continues for life with ongoing government premium support, no medical underwriting, and nationwide provider networks. But continuation is not automatic. You must satisfy two core requirements, and you must understand how FEHB coordinates with Medicare once you turn 65.

Key facts

• 5-year rule: continuous FEHB enrollment is required for the 5 years immediately before retirement.
• Government contribution: the government continues to pay approximately 72% of the weighted average premium in retirement.
• Immediate retirement: you must retire on an immediate annuity, not a deferred retirement, to continue FEHB.
• Medicare coordination: enhanced benefits are available when you enroll at age 65.
• PSHB transition: postal employees moved to the separate PSHB program during 2025 to 2026.

FEHB continuation requirements

Keeping your Federal Employees Health Benefits in retirement requires meeting specific eligibility criteria and understanding coordination rules with Medicare. Four things matter most.

• The 5-year rule: you must be continuously enrolled in FEHB for 5 consecutive years immediately before retirement. This means no gaps in coverage, including periods when you were covered under a spouse's plan.
• Immediate retirement: you must retire on an immediate annuity, not a deferred retirement, to continue FEHB. Postponed or deferred retirements do not qualify for health benefits continuation.
• Plan selection: choose your retirement FEHB plan carefully during Open Season before retirement. You can change plans annually, but some restrictions apply for new enrollments.
• Medicare coordination: at age 65, Medicare becomes primary and FEHB becomes secondary. Many plans offer enhanced benefits for Medicare enrollees, including waived deductibles and reduced copays.

The FEHB advantage

FEHB provides excellent value in retirement with continued government premium support and comprehensive coverage options nationwide. The government continues to pay approximately 72% of the weighted average premium, and there are more than 200 plan options available across the program. For many retirees, keeping FEHB is worth thousands of dollars per year compared with buying comparable coverage on the open market.

FEHB also offers benefits that are unavailable in individual Medicare plans or in employer retiree coverage from other organizations:

• Continued government premium support in retirement.
• No medical underwriting, ever.
• Nationwide provider networks.
• Enhanced Medicare coordination.
• Prescription drug coverage.
• Dental and vision options.
• Annual Open Season flexibility.
• Spouse continuation options.

Medicare plus FEHB: strategic coordination

The combination of Medicare and FEHB often provides better coverage than either alone. Strategic coordination ensures you maximize benefits while minimizing costs through proper enrollment timing and plan selection. Two decisions drive most of the outcome.

• Medicare enrollment timing: enroll in Medicare Part A (premium-free if you have 40 quarters of Medicare-covered employment) and Part B at age 65 to avoid permanent late-enrollment penalties. Medicare becomes primary, with FEHB providing secondary coverage.
• Enhanced plan benefits: many FEHB plans offer special benefits for Medicare enrollees, including waived deductibles, reduced copays, and enhanced prescription drug coverage coordination. Because Medicare pays first and FEHB pays second, most federal retirees find this combination provides excellent coverage without needing a separate Medicare Supplement (Medigap) policy.

A note for postal employees: the PSHB transition

The Postal Service Health Benefits (PSHB) program was created as a separate health insurance program for postal employees and retirees, distinct from FEHB. During 2025 to 2026, postal employees and annuitants were transitioned from FEHB to PSHB. PSHB plans are similar to FEHB but are specifically designed for the postal workforce, and postal retirees in PSHB must enroll in Medicare Part A and Part B when eligible. If you are a postal employee approaching retirement, understanding the PSHB enrollment requirements and plan options is essential, because the rules differ from traditional FEHB in important ways.

FEHB planning FAQ

Can I keep FEHB in retirement?

Yes, but you must meet two requirements: (1) You must retire on an immediate annuity (not a deferred retirement), and (2) You must be enrolled in FEHB for the 5 years immediately before retirement. There are limited exceptions to the 5-year rule for certain circumstances like returning from active military duty. If you meet these requirements, you can keep FEHB for life, and the government continues to pay approximately 72% of the weighted average premium just as they did while you were working.

Do I need Medicare if I have FEHB?

Most federal retirees should enroll in Medicare Part A (which is premium-free if you have 40 quarters of Medicare-covered employment) and Part B when they turn 65. Medicare becomes your primary insurance and FEHB becomes secondary, which can significantly reduce your out-of-pocket costs. Some FEHB plans waive deductibles and copays for Medicare-enrolled members. Delaying Medicare Part B enrollment can result in permanent late-enrollment penalties. We recommend reviewing your specific FEHB plan's Medicare coordination benefits before deciding.

What is the 5-year rule?

The 5-year rule requires continuous FEHB enrollment for the 5 years immediately preceding your retirement to carry FEHB into retirement. This means 5 consecutive years, not 5 total years. If you weren't enrolled in FEHB, were covered under a spouse's plan, or had a lapse in coverage during those last 5 years, you may not be eligible to continue FEHB. Limited exceptions exist for employees who return from active military service or lose coverage under a spouse's FEHB enrollment. It's critical to verify your eligibility well before your planned retirement date.

How does FEHB coordinate with Medicare?

Once you enroll in Medicare, it becomes your primary payer and FEHB becomes secondary. This means Medicare pays first, then your FEHB plan pays some or all of what Medicare doesn't cover, depending on your specific plan's coordination rules. Many FEHB plans offer enhanced benefits for Medicare enrollees, such as waived deductibles or reduced copays. You continue paying your FEHB premium, but your combined coverage (Medicare plus FEHB) is typically better than either alone. Most federal retirees find this combination provides excellent coverage without needing a Medicare Supplement (Medigap) policy.

What changed with PSHB for postal employees?

The Postal Service Health Benefits (PSHB) program was created as a separate health insurance program for postal employees and retirees, distinct from FEHB. Starting in 2025 to 2026, postal employees and annuitants were transitioned from FEHB to PSHB. PSHB plans are similar to FEHB but are specifically designed for the postal workforce. Postal retirees in PSHB must enroll in Medicare Part A and Part B when eligible. If you're a postal employee approaching retirement, understanding the PSHB enrollment requirements and plan options is essential, since the rules differ from traditional FEHB in important ways.
