FEHB Five-Year Rule: 5 Facts to Protect Your Retiree Coverage

The short answer: The FEHB five-year rule generally lets you keep federal health coverage in retirement if you retire on an immediate annuity. You must also have been continuously enrolled in any FEHB plan, or covered as a family member, for the five years before retirement. There is no partial credit — falling short by even a month generally means coverage does not continue.

For many federal employees, health coverage is one of the most valued parts of the benefits package. The FEHB five-year rule is the test that decides whether that coverage can follow you into retirement. Understanding how it works well before your retirement date may help you avoid an unwelcome surprise.

Key takeaways

• The FEHB five-year rule requires continuous enrollment for the five years immediately before retirement, or since your first opportunity to enroll (OPM).
• You must also be entitled to retire on an immediate annuity.
• Coverage under TRICARE, or as a family member on someone else’s FEHB enrollment, can count — provided you hold an FEHB plan on your retirement date.
• There is no partial credit, and OPM waivers are limited and discretionary.
• The government continues paying its share of the premium in retirement — generally around 70% of the total under OPM’s formula — which is much of why the benefit matters.

What is the FEHB five-year rule?

The FEHB five-year rule is the eligibility test for carrying Federal Employees Health Benefits coverage into retirement. According to OPM, you generally must be entitled to retire on an immediate annuity. You must also have been continuously enrolled, or covered as a family member, in any FEHB plan for the five years immediately before your annuity starts.

• Two conditions must both be met. OPM states you must be entitled to retire on an immediate annuity. You must also have been continuously enrolled in FEHB for the required period (OPM Eligibility).
• “Any FEHB plan” counts. The five years do not have to be in the same plan or option; switching plans during Open Season does not reset the clock, per OPM.
• Family member coverage can count. Time covered as a family member under another person’s FEHB enrollment counts toward the five years, according to OPM.
• TRICARE time may count. Time covered under TRICARE can count toward the requirement. This applies if you are enrolled in an FEHB plan on the date you retire (OPM Annuitants reference).
• Waivers exist but are limited. OPM may waive the five-year requirement only in narrow circumstances, and the request must be made to OPM.

What exactly does the five-year enrollment requirement mean?

It means you must have been covered under the FEHB Program for the five years of service immediately before retirement. OPM describes this as continuous enrollment in any FEHB plan, or coverage as a family member, during that window.

An important detail is the word “any.” You do not need to stay in one plan or one option for five years. Changing carriers, switching from Self Only to Self Plus One, or moving plans during Open Season does not interrupt the count. The key is that some FEHB coverage stays in place.

Equally important is what the rule does not offer: partial credit. The requirement is measured as a continuous period, and coming up short — even by a month — generally means coverage cannot be carried into retirement. That is why the timing of a retirement date often gets reviewed alongside the enrollment history itself.

What if you have fewer than five years of service?

OPM addresses this directly. If you have been eligible for FEHB for less than five years, a different test applies. You must have been enrolled for all service since your first opportunity to enroll. In other words, newer employees can still qualify if they signed up at their earliest chance and stayed covered.

How does the immediate annuity part of the FEHB five-year rule work?

The first half of the FEHB five-year rule is that you must be entitled to retire on an immediate annuity. An immediate annuity is one that begins within roughly a month after you separate from service.

OPM notes that this includes a Federal Employees Retirement System (FERS) Minimum Retirement Age (MRA) + 10 retirement. Employees retiring under the MRA + 10 provision can still meet this part of the test. That holds even if they choose to postpone receiving the annuity. Confirming eligibility for an immediate annuity is a step some people take alongside checking the enrollment side of the rule.

What happens to FEHB if you postpone the annuity?

This is where the mechanics catch people out. An employee who separates under MRA + 10 and postpones the annuity to reduce the age reduction does not simply keep FEHB running in the meantime. Coverage is suspended during the postponement period, and enrollment can resume when the annuity actually begins.

The five-year test still has to have been satisfied as of separation. The rule follows a postponed retirement rather than pausing with it, so anyone weighing that path generally confirms the specifics with their agency benefits officer before leaving.

Can TRICARE or family coverage count toward the requirement?

Yes, in defined situations. OPM states that time covered under the Uniformed Services Health Benefits Program, also known as TRICARE, can count toward the five-year requirement. This credit applies as long as you were covered under an FEHB enrollment at the time of your retirement.

This combination matters for many former service members. Being under TRICARE alone does not satisfy the rule. The published guidance ties the credit to having FEHB coverage in place on your retirement date. Time covered as a family member under someone else’s FEHB enrollment may also count toward the five years.

What about suspending FEHB for TRICARE or Medicare?

Separately from the five-year test, OPM allows eligible annuitants to suspend FEHB rather than cancel it. This option covers annuitants eligible for TRICARE, TRICARE-for-Life, CHAMPVA, Medicare Advantage, or Medicaid. They may suspend FEHB and later return during Open Season. They can also return immediately if they involuntarily lose the other coverage. Suspending preserves the ability to come back, which canceling does not. The trade-offs involved are covered in more depth in our look at suspending FEHB when you have TRICARE.

Who is most at risk of missing the five-year rule?

Three situations come up repeatedly, and all three are visible years in advance if the enrollment history gets reviewed early.

• Employees who declined FEHB to stay on a spouse’s private plan. The clock does not start until FEHB coverage does, unless the spouse’s plan is itself an FEHB enrollment.
• Employees who dropped FEHB during a tight budget year. A lapse of a few months in the middle of a career is harmless; the same lapse inside the final five years is not.
• Late-career hires. Someone who enters federal service within five years of their intended retirement date may simply run out of runway, which is where the “since first opportunity to enroll” test becomes the relevant one.

How can you confirm your own eligibility before retiring?

Review your enrollment history early, because a gap caught years ahead is far easier to address than one discovered at the last minute. The proof sits in specific documents, and some periods that look like coverage do not count toward the five years. Our guide to verifying your FEHB enrollment history walks through the four records that prove it and who makes the final determination.

The same records feed related decisions: how you elect a FERS survivor annuity so a spouse can keep FEHB, the broader FEHB eligibility verification process, and your FEHB retirement healthcare costs. A break in service sometimes leads employees to temporary continuation of coverage, which bridges a gap but does not satisfy the five-year requirement.

How does the five-year rule connect to Medicare?

Meeting the rule does not require dropping FEHB at 65. Many retirees keep FEHB and add Medicare, coordinating the two to reduce out-of-pocket costs. That coordination is where a large part of the long-term value shows up, and it is the subject of our look at the FEHB and Medicare Part B decision.

The sequencing matters, though. Those options only exist for someone who satisfied the five-year test in the first place. Failing it does not produce a reduced benefit or a more expensive one — it generally ends FEHB eligibility at retirement.

Why does the rule exist at all?

FEHB is heavily subsidized, and the government continues paying its share of the premium into retirement. Without a participation requirement, an employee could enroll shortly before separating and carry that subsidy for life.

The five-year test ties lifetime coverage to a real period of participation instead. Seen that way, the strictness is the point, and it also explains why waivers remain uncommon.

Is a waiver of the FEHB five-year rule ever possible?

It can be, but only in limited cases. OPM may waive the five-year requirement when it determines that meeting it would be against equity and good conscience. You must request the waiver from OPM.

Waivers are discretionary and uncommon. Many people treat the standard five-year path as the reliable route. They view a waiver as a fallback rather than a plan. OPM’s FEHB Handbook outlines the steps for requesting one.

Frequently asked questions about the FEHB five-year rule

Do the five years have to be in the same FEHB plan?

No. OPM specifies continuous enrollment in “any FEHB plan(s).” You can switch plans or options during Open Season without restarting the five-year count. The key is that some FEHB coverage remains in place.

Does coverage as a family member count toward the five years?

Yes. OPM states that time covered as a family member can count toward the five-year requirement. This applies when you are covered under another person’s FEHB enrollment.

I have fewer than five years of federal service. Can I still qualify?

Possibly. OPM notes a different test for those eligible for less than five years. You generally must have been enrolled for all service since your first opportunity to enroll.

Does TRICARE count toward the FEHB five-year rule?

It can. Time covered under TRICARE may count toward the requirement. OPM ties this credit to being enrolled in an FEHB plan on the date you retire.

What if I am one month short?

There is no partial credit. Falling short of the continuous five-year period generally means FEHB cannot be carried into retirement, absent an OPM waiver. This is why the retirement date itself is often reviewed against the enrollment history.

What happens if I do not meet the requirement?

Generally, FEHB coverage cannot continue into retirement unless OPM grants a waiver. OPM may waive the requirement only in limited circumstances. You must submit the request to OPM.

Can I suspend FEHB in retirement instead of canceling it?

Yes. OPM allows eligible annuitants with coverage such as TRICARE, CHAMPVA, or a Medicare Advantage plan to suspend FEHB and return later. Suspending preserves future eligibility in a way that canceling does not.

If I postpone an MRA + 10 annuity, does FEHB continue?

Not during the postponement. Coverage is suspended while the annuity is postponed and can resume once it begins, provided the five-year test was met at separation.
