I firmly believe that leaving your future to chance is a recipe for a stressful retirement. When federal employees begin fantasizing about their last day in the office, they often overlook the fine print surrounding their most valuable asset: their health insurance.
Unlike the private sector, the federal government pays roughly 72 to 75 percent of your Federal Employees Health Benefits (FEHB) premiums, and incredibly, they continue to subsidize that cost throughout your retirement. Because medical expenses tend to peak in our later years, keeping this coverage is a critical piece of your retirement planning that can save you hundreds of thousands of dollars over your lifetime.
However, many federal employees operate under the dangerous misconception that having FEHB for any random five years of their career is enough to carry it into retirement. To protect what you’ve worked a lifetime to accumulate, let’s navigate the facts, the exceptions, and the devastating traps of the FEHB 5-Year Rule.
The Golden Rule of FEHB
In a nutshell, the 5-Year Rule mandates that to keep your FEHB coverage into retirement, you must be continuously enrolled in the program for the five consecutive years immediately preceding your retirement date.
If you are planning to retire on December 31, 2025, you must have been continuously enrolled in the FEHB program since at least December 31, 2020. If your coverage didn’t become effective until January 1, 2021, you would miss the 5-year mark and lose your eligibility to keep your federal health insurance in retirement.
The Nuances: Spouses, Plan Changes, and Breaks in Service
Fortunately, the government provides some flexibility within this rule:
- Spousal Coverage Counts: What if you waived your own FEHB coverage because you were covered under your federal spouse’s FEHB plan? That is perfectly fine. As long as you were continuously covered under the FEHB umbrella—regardless of whose name the policy was under or whether you switched from Self Only to Self and Family—you meet the criteria.
- Plan Switching: Making changes to your provider during Open Season (like switching from
Blue Cross Blue Shield to GEHA) does not break your continuous coverage - Breaks in Federal Service: If you leave federal service to work in the private sector and later return, OPM only counts your periods of actual federal service. For example, if you had FEHB for three years, left for the private sector for a year, and then returned as a fed for two more years before retiring, those five years of federal service are stitched together to satisfy the rule.

The TRICARE Exception
There is a fantastic exception for our military retirees. If you are covered by TRICARE, that time actually counts toward the 5-year FEHB requirement. However, you must be officially enrolled in an FEHB plan on the exact day you retire to carry it into retirement. Once retired, you even have the option to suspend your FEHB coverage to avoid paying premiums while using TRICARE, with the safety net of being able to re-enroll in FEHB during a future Open Season if your needs change.
The Ultimate Trap: The Immediate Annuity Requirement
Meeting the 5-year coverage requirement is only half the battle. To keep your FEHB, you must also retire on an “immediate pension,” meaning your annuity must be eligible to begin within 30 days of your separation.
This is where many feds make a catastrophic mistake.
- Deferred Retirement (The Worst Case Scenario): If you leave federal service before you are fully eligible to retire (for example, leaving at age 40 with 10 years of service) and wait until age 62 to collect your pension, this is a deferred retirement. In a deferred retirement, your FEHB is lost forever. You cannot get it back when your pension finally starts.
- Postponed Retirement (The Safe Alternative): If you reach your Minimum Retirement Age (MRA) with at least 10 years of service, you are eligible for an immediate MRA+10 retirement, but your pension takes a 5% penalty for every year you are under age 62. If you choose to leave the government and postpone receiving your pension to avoid this penalty, your FEHB coverage will be temporarily suspended. However, unlike a deferred retirement, your FEHB coverage will be fully restored when you eventually decide to begin drawing your pension.
The Bottom Line When it comes to your health insurance, do not assume anything! If you suddenly have an accident or become ill in retirement without coverage, you could burn through your entire Thrift Savings Plan (TSP) stash in no time.
If you are cutting it close to the 5-year mark, sit down with your HR counselor and double-check your effective dates before you set your retirement date. Always look at the effective date of your enrollment, not the date you filled out the paperwork. A little preparation today guarantees peace of mind for the ones you love most tomorrow. Please forward this article to anyone in your organization who is contemplating retirement so they don’t walk out the door and leave their benefits behind!
