One of the most common five-year-rule questions I get is some version of: “I’ve changed my FEHB plan twice in the last three years. Have I broken the clock?” The short answer is almost always no. The longer answer is more useful, because there are a few specific things that do break continuous coverage, and they are easy to confuse with the things that do not.
The five-year rule asks a single question: was there any moment during the final five years when you were not enrolled in FEHB? Plan changes do not create that moment. Waiving FEHB does.
What is allowed during the five-year window.
Inside the five-year window, you can do almost anything to your FEHB enrollment except stop being enrolled. The following changes are routine, and none of them reset the five-year clock:
1. Changing FEHB plans.
During Open Season or a Qualifying Life Event, you can switch from one FEHB plan to another — BCBS Basic to GEHA Standard to Aetna Direct to a high-deductible plan, whatever your current priorities are. The five-year clock does not care which plan you were in. It cares that you were in some plan.
2. Switching from Self Only to Self Plus One or Self & Family.
Marriage, the birth of a child, gaining an eligible dependent — all of these are QLEs that allow you to expand your enrollment tier. You can also narrow the tier during Open Season in some cases. None of these changes break continuous coverage.
3. Switching carriers.
Many FEHB carriers operate the same plan type (Standard Option, Basic Option, High Deductible, etc.) under different names. Some years your plan is run by one carrier; other years it is run by another. As long as your enrollment remained continuously in force, the clock continues to run.
4. Changing payroll offices.
A transfer between agencies, a move from one payroll provider to another, a switch from the standard payroll system to a special payroll — none of these are breaks in coverage as long as your enrollment was transferred with you and the deductions continued without a gap.
What actually breaks the clock.
The things that do break continuous coverage are narrower than federal employees usually fear, but they are also harder to undo:
1. Waiving FEHB outright.
If you complete a waiver form (or equivalent electronic action) that cancels your FEHB enrollment — usually in favor of a spouse’s private plan, TRICARE, or an individual market plan — the five-year clock stops. Re-enrollment restarts the clock, but the lost years are not recovered.
2. A lapse in payroll deductions.
If, for any reason, FEHB deductions stop being taken from your paycheck and the enrollment is allowed to lapse, the clock breaks. This is rare but it happens — usually as the result of an administrative error, an unpaid leave status that nobody reconciled, or a transfer where the paperwork did not catch up.
3. A break between active employment and a return to federal service.
If you leave federal service entirely (resignation, RIF, anything other than approved leave), your FEHB enrollment typically ends at the end of the pay period in which you separated. The months between that separation and a return to federal service are not covered by FEHB and do not count toward the five-year clock.
The change that feels like a break but is not.
A surprisingly common source of confusion: a federal employee goes on military leave for a deployment and returns. While deployed, they have TRICARE. When they return, their FEHB enrollment resumes. The months of TRICARE coverage do not count toward the five-year rule, but the FEHB enrollment that resumes after deployment doescount. The clock does not run during deployment, but it picks up where it left off on the other side.
The way to think about the rule: it is a question about whether FEHB was in force at any given moment, not a question about whetherany health coverage was in force. Multiple sources of coverage can coexist (you can have FEHB and Medicare, for example, and both will count for their own purposes), but only FEHB counts toward the FEHB five-year rule.
The take-away for someone inside the window.
If you are inside the five-year window, the message is simple: keep FEHB in force. Change plans as much as you want. Change tiers, change carriers, change everything except the enrollment itself. The cost of dropping FEHB to chase a marginal premium savings during the final five years is paid in the only currency that matters later — FEHB coverage for life.
