If a medical condition has made it impossible to do your job, you may already know that federal disability retirement exists. What you may not know is that the rules protecting applicants have quietly gotten stronger over the past three decades — and a recent court ruling just closed one more door OPM used to deny claims.
The Basic Benefit
FERS employees with as little as 18 months of federal civilian service can retire on disability if a medical condition prevents them from performing the essential duties of their specific position — not any job, just theirs — and the condition is expected to last at least a year. You don’t need to be totally disabled. An employee who can no longer handle the physical or psychological demands of their exact role may qualify even if they could still work elsewhere.
The annuity itself starts at 60% of your high-3 average salary for the first year (offset by any Social Security disability benefit), then drops to 40% starting in year two, until it’s recomputed under the regular FERS formula at age 62.
The Rule That Shifted the Burden
For a long time, applicants carried the full weight of proving their case. That changed in 1993 with Bruner v. OPM, a federal appeals court ruling involving a VA nursing assistant terminated for chronic back pain. The court held that if your agency removes you specifically for medical inability to perform your job, that removal itself is evidence you’re entitled to disability retirement, and the burden shifts to OPM to prove otherwise, rather than the other way around.
Over time, the Merit Systems Protection Board has expanded this protection further, including to certain removals for extended absences when the underlying cause was a medical inability to work.
The Latest Development
This year, the door closed a little further. In a 2026 ruling, the Federal Circuit held that OPM can’t rebut this presumption simply by claiming an applicant’s medical evidence isn’t “objective” enough — that argument alone isn’t sufficient to deny a claim. It’s a narrower, more technical ruling than Bruner itself, but it matters for the same reason: it’s one less shortcut available to deny a legitimate claim.
What This Means If You’re Considering It
Two deadlines matter more than anything else: you must apply while still employed or within one year of separation, and FERS also requires you to file for Social Security disability (though not necessarily be approved). Miss either window, and the benefit may be gone for good.
If a medical condition and your position are no longer compatible, the standard for this benefit is more workable than most people assume, and three decades of case law have moved consistently in applicants’ favor.
