Key Takeaways
- FEHB can often be continued into federal retirement if eligibility criteria are met.
- Recent changes in 2026 impact both eligibility and Medicare integration for retirees.
Many eligible federal retirees maintain FEHB coverage into retirement, making it one of the most valued benefits for former federal employees. Understanding how FEHB rules work when leaving service and retiring is essential for making informed decisions about your future health care.
What Happens to FEHB When You Retire?
Eligibility for continued FEHB coverage
When you retire from federal service, the Federal Employees Health Benefits (FEHB) program can generally continue, provided you satisfy key eligibility requirements. You must be entitled to retire on an immediate annuity—a monthly payment that begins shortly after leaving service. Additionally, you need to have been continuously enrolled in FEHB, or covered as a family member, for at least the five years before your retirement date (or for the entire period of service if employed less than five years).
How retirement affects premiums
After retirement, your FEHB premiums are typically deducted from your annuity rather than your pay. The OPM continues to pay a substantial portion of the overall premium, much like during your employment. However, there’s no employer contribution if you convert to Temporary Continuation of Coverage (TCC) or an individual policy. Importantly, the share you pay as a retiree usually remains similar to what you paid as an active employee, although you now pay with post-tax dollars.
Enrollment requirements at separation
You must be enrolled in FEHB on the day you separate from federal service in order to carry coverage into retirement. If you’re covered as a family member on another federal employee’s plan, that counts toward eligibility. It’s essential to review your enrollment status before departing to ensure you meet all requirements for continued coverage.
Can You Keep FEHB After Leaving Service?
Qualifying for FEHB in retirement
Most federal workers who retire on an immediate annuity and meet the five-year (or all service) enrollment rule are eligible to keep FEHB. This benefit extends to both Civil Service Retirement System (CSRS) and Federal Employees Retirement System (FERS) retirees. Keeping continuous FEHB coverage not only provides peace of mind but also extends to eligible family members if you elect survivor benefits.
What if you leave before retirement?
If you separate from service before qualifying for retirement (such as resigning without immediate annuity eligibility), you generally lose access to FEHB as a regular enrollee. In these cases, you can elect Temporary Continuation of Coverage (TCC), which provides up to 18 months of coverage post-separation, but at your own full cost plus an administrative fee. TCC does not include an employer premium contribution.
FEHB vs. Temporary Continuation of Coverage
FEHB for retirees and TCC are not the same. With FEHB in retirement, you receive an annuitant’s subsidy, making costs more manageable, and coverage continues as long as you receive an eligible federal annuity. With TCC, coverage is time-limited, more expensive, and does not carry over into retirement unless you return to federal service and retire thereafter.
How Does FEHB Work With Medicare?
Coordination of FEHB and Medicare Parts A and B
Once you reach age 65, you become eligible for Medicare. Most federal retirees remain enrolled in FEHB and may choose to enroll in Medicare Parts A and B as well. FEHB and Medicare are designed to coordinate, with Medicare typically acting as primary payer for retirees. This means Medicare pays first for covered services, and FEHB acts as secondary payer, often picking up many remaining costs.
FEHB during employment vs. retirement
While you’re still employed, FEHB is generally your primary coverage and Medicare is secondary (for active federal employees age 65+). Once retired, this reverses: Medicare becomes primary, and your FEHB plan pays secondary, which may reduce your out-of-pocket health expenses. If you are not enrolled in Medicare Part B, your FEHB plan continues as the main source of coverage after retirement.
Optional considerations for Medicare enrollment
Enrollment in Medicare Part A is automatic for most and premium-free, so it usually makes sense for eligible retirees. Medicare Part B requires a premium and is optional—many retirees weigh the additional cost against potential savings in out-of-pocket expenses. OPM notes you aren’t required to enroll in Part B to keep your FEHB, but many do for extra coverage and reduced copayments.
Do Former Employees Lose Health Benefits?
Impact of resigning before retirement age
If you resign from federal service before reaching the minimum retirement age or meeting eligibility for an immediate annuity, you cannot continue FEHB coverage permanently. Instead, your options are more limited, as you wouldn’t qualify to carry FEHB into retirement directly.
Coverage extensions under TCC
Temporary Continuation of Coverage (TCC) provides a short-term safety net, allowing former employees and their dependents to maintain FEHB for up to 18 months after separation. Premiums under TCC are higher since there is no government contribution. This option is helpful if you need time to transition to another health plan.
Conversion to individual policies
When TCC coverage ends, you may have the right to convert your group FEHB coverage to individual (nongroup) health insurance with the carrier that provided your FEHB plan. This conversion may involve different coverage rules and higher premiums. The individual policy will not include any federal government subsidization.
What Rules Changed for Retirees in 2026?
Recent updates to FEHB eligibility
In 2026, minor updates streamlined FEHB eligibility reviews for retirees, ensuring clearer documentation and verification during the pre-retirement period. The core five-year rule remains, but increased digitalization of records has made compliance verification more efficient.
Windfall Elimination Provision repeal and effects
As of 2025, the Windfall Elimination Provision (WEP) has been repealed. Federal Employees Retirement System (FERS) retirees and their Social Security benefits are no longer affected by the WEP, removing what was previously a reduction in certain Social Security benefits for those with a federal pension.
Medicare integration updates
OPM clarified that retirees are still not required to enroll in Medicare Part B to keep their FEHB coverage. However, in 2026, new informational materials were distributed, helping retirees more easily compare FEHB and Medicare features to make informed coverage decisions. There were no substantive changes to integration mechanics, but transparency has improved.
What Are Important Considerations for FEHB?
Enrollment decision points
When planning retirement, consider your FEHB options: whether to maintain coverage, change health plans during Open Season, or add family members. Evaluate your eligibility to keep FEHB and any timelines for required actions. Missing enrollment windows may result in loss of coverage or restricted choices.
Cost factors during and after retirement
Compare the cost of FEHB between employment and retirement, noting the post-tax nature of annuitant premium payments. Include potential costs for Medicare coordination. If you anticipate higher medical needs in retirement, consider how both FEHB and Medicare can address those needs.
Family member eligibility in retirement
Spouses and eligible children can continue coverage under your FEHB if enrolled before retirement. If you select a survivor annuity, surviving spouses and qualified dependents generally may keep FEHB coverage after your death. Be mindful of beneficiary designations and coverage elections before leaving federal service.
