What Conditions Qualify for Federal Disability Retirement?

Any disease or injury that prevents a federal employee from performing the essential duties of their position, and that is expected to last at least a year, can qualify for federal disability retirement. There is no official list of conditions that automatically qualify and none that are automatically excluded. The Office of Personnel Management (OPM) looks at your specific medical condition against your specific job, so what conditions qualify for federal disability retirement is answered case by case rather than by diagnosis.

The Standard Is Functional, Not Diagnostic

The governing statute requires OPM to find that the employee is “unable, because of disease or injury, to render useful and efficient service” in their position.¹ That phrase does the work. You do not need to be completely incapacitated. You need to show that your condition makes it impossible to perform the essential functions of your job at an acceptable level, and that the condition is expected to last at least one year.²

Two employees with the same diagnosis can get opposite results. A postal carrier with severe knee degeneration faces a different analysis than a desk-bound analyst with the same condition, because the carrier’s job requires standing and walking that the analyst’s does not. What qualifies is always the fit between the condition and the duties.

The cause does not matter. The condition does not have to be work-related. An injury from a weekend accident, a genetic illness, or a mental health condition that has worsened over time can all support an approval if they meet the functional standard.

Conditions That Commonly Support Approved Claims

While OPM decides each case on its facts, several categories of conditions regularly form the basis for successful applications:

Musculoskeletal disorders such as chronic back injuries, severe arthritis, or joint deterioration that prevents standing, walking, lifting, or prolonged sitting as the job requires.
Mental health conditions including major depression, PTSD, severe anxiety, and bipolar disorder that interfere with concentration, decision-making, attendance, or interactions the position demands.
Cardiovascular conditions, including heart disease and related disorders that limit physical exertion or create safety risks in physically demanding roles.
Neurological conditions such as multiple sclerosis, traumatic brain injury, or chronic migraine disorders that impair the cognitive or physical function a position needs.
Autoimmune and chronic illnesses such as lupus, Crohn’s disease, or chronic fatigue syndrome that cause unpredictable flares making consistent attendance or performance impossible.

None of these qualify automatically. Each qualifies when the medical evidence shows it prevents useful and efficient service in the applicant’s actual position.

What Your Medical Evidence Has to Show

A diagnosis alone proves nothing to OPM. Most weak applications fail here: they document the condition thoroughly but never explain precisely which job duties the employee can no longer perform and why. The evidence needs to make three connections in sequence.

First, the diagnosis. The physician’s statement, filed on SF 3112C, provides the diagnosis, prognosis, and treatment history. Objective backup matters: test results, imaging reports, and treatment notes should accompany the statement so OPM reviewers can see a medical basis for the limitations, not just a physician’s conclusory opinion.

Second, the functional limitations that flow from the diagnosis. Vague language like “patient is unable to work” carries almost no weight. The statement needs concrete detail. If your condition prevents you from standing longer than 20 minutes, lifting more than 10 pounds, sustaining concentration for more than short intervals, or maintaining regular attendance during flares, it needs to say so in those terms.

Third, the tie between those limitations and specific duties in your position description. If your job requires standing for six hours and your condition caps standing at 20 minutes, that gap has to be spelled out. The applicant’s own statement (SF 3112A) and the supervisor’s statement (SF 3112B) sit alongside the physician’s, describing the job’s demands and any performance problems tied to the condition from those two vantage points. The whole package answers one question: does this condition prevent this employee from doing this job.

Service and Filing Requirements That Gate Eligibility

A qualifying condition still has to meet the program’s threshold rules. Federal disability retirement has no minimum age, but it does have service and filing requirements:

FERS employees need at least 18 months of creditable civilian service.¹
CSRS employees need at least five years of creditable civilian service.³
The application must reach OPM before you separate or within one year after separation. File later than that and OPM will reject the application as untimely no matter how serious the condition.²
FERS applicants must also apply for Social Security Disability Insurance. OPM will not fully process a FERS disability application without confirmation that you filed for SSDI, and withdrawing the SSDI application causes OPM to dismiss the disability retirement application.²

A 28-year-old FERS employee with 18 months of service and a disabling condition has the same right to apply as a 55-year-old with decades in.

Accommodation and Reassignment Can Still Block Approval

Even a clearly qualifying condition can lead to a denial if your agency can keep you working. Before OPM approves disability retirement, the agency has to show it considered accommodating your condition in your current position and reassigning you to a different position you could handle. The statute bars disability retirement for any employee who declined a reasonable reassignment offer to a vacant position at the same grade or pay level, within the same commuting area, where the employee could provide useful and efficient service.¹

The reassignment has to be genuinely suitable. A position requiring the same physical demands your condition prevents, or one in a different city, does not count. The agency documents its search on SF 3112D, the Agency Certification of Reassignment and Accommodation Efforts, and that certification becomes part of your application package.

How Long the Condition Has to Last, and What Happens Later

The one-year duration requirement is a minimum, not a permanence test. Conditions expected to resolve in a few months do not qualify; conditions expected to last a year or longer can, and permanent conditions certainly do.

After approval, federal law requires OPM to schedule medical reexaminations at the end of the first year and annually until you turn 60. If OPM decides your condition has improved enough that you could return to useful and efficient service, it can terminate the annuity. Failing to submit to a required examination results in suspension of payments until you comply.⁴ The statute lets OPM waive that annual review for disabilities that are permanent in character, but OPM makes that call. Until you have written confirmation that reviews are waived, treat every reexamination notice as mandatory.

The practical takeaway on what qualifies: the condition itself is only half the question. The other half is the evidence tying it to the specific duties you can no longer perform. Applications that pair a clear diagnosis with a detailed, duty-by-duty account of the limitations, backed by medical records, are the ones OPM approves. Applications that document the illness but leave the job connection to inference are the ones that come back denied.
