For permanent retirement consideration, the disability must be what?

• A. Reversible
• B. Progressive
• C. A disabling condition that is determined to be stable
• D. Untreatable

Answer: (C)

The main idea is that permanent disability retirement is granted only when the disability is stable. A stable condition is one that is not expected to improve with further medical treatment or over time. If a disability is stable, there’s no reasonable expectation that it will get better, so it can be considered permanent for retirement purposes.

Reversible implies the condition could improve, so it wouldn’t be permanent. Progressive suggests the condition is likely to worsen, which also undermines permanence. Untreatable isn’t the defining factor here; a condition can be untreatable yet stable, but the test for permanent retirement is the stability itself.
