The FEHB Five-Year Rule: The Retirement-Date Check Most People Skip

Ask a room of federal employees what they'll miss least about work and you'll hear commutes, meetings and performance reviews. Ask what they'd least like to lose and the answer, more often than not, is their health coverage. FEHB in retirement is one of the most valuable benefits federal service offers. It's also one of the few that can be lost through timing alone.

The rule, in one sentence

To carry your Federal Employees Health Benefits coverage into retirement, you generally need to have been enrolled in FEHB for the five years of service immediately before you retire — or, if you haven't had five years of opportunity, for all of your service since your first opportunity to enrol.

That's it. Two details in that sentence do most of the work.

• "Immediately before." It's the five years leading up to your retirement date, not any five years across a career. A gap near the end can matter more than decades of coverage earlier on.
• "Enrolled." Coverage as a family member under someone else's FEHB enrolment, such as a spouse who is also a federal employee, generally counts. Coverage through an outside employer generally doesn't. OPM sets out the specifics; if your history is anything other than straightforward, check it against their guidance rather than ours.

Why it catches people

Most career federal employees meet the rule without ever thinking about it. The people it catches tend to share a few patterns:

• They dropped FEHB for a while. Perhaps a spouse's private-sector plan was cheaper, or they were covered through the military. Years later, that decision quietly sits inside the five-year window.
• They came back to federal service late. A second stint of government work, close to retirement, can leave less runway than people assume.
• They retire on a type of retirement that doesn't carry coverage over at the moment they leave. How and when your pension starts interacts with when FEHB can continue. That's its own subject, covered in our piece on retiring at your MRA.

OPM can waive the requirement in limited circumstances, but waivers are the exception. Planning on one isn't a plan.

What the rule doesn't do

Meeting the five-year rule keeps the door open. It doesn't make retirement health costs disappear.

• Premiums continue. In retirement your share is typically taken from your monthly pension. That's money worth including when you size the gap your TSP has to fill.
• Your plan choice can still change. Retirees generally take part in Open Season like everyone else, so you aren't locked into the plan you held on your last day.
• Medicare is a separate decision. How FEHB and Medicare fit together at 65 is a question in its own right, and the answer depends on your plan and your health. It's worth reading your plan's materials and OPM's guidance well before that birthday.

Life insurance has a similar rule

Federal Employees' Group Life Insurance follows a parallel idea: to continue basic FEGLI into retirement you generally need to have been covered for the five years before you retire. The mechanics and the costs in retirement are different from FEHB, and they're worth looking at separately — but if you're checking one five-year window, check both.

Where to go from here

Your agency's HR office and OPM's retirement pages are the authorities on whether you meet the rule. Once you know your coverage is secure, the remaining questions are about money: what your pension and Social Security cover, and what's left for your TSP. The FERS pension gap walks through that arithmetic, and The TSP Secure Path puts the whole decision in order.
