Long COVID / post-viral fatigue: Documentation That Wins a Disability Claim
Long COVID / post-viral fatigue claims: evidence needed — excluded conditions ruling + pulmonary/cognitive testing. Typical outcome: highly contested.

| Key evidence | Excluded conditions ruling + pulmonary/cognitive testing |
| Typical outcome | Highly contested |
Post-viral syndromes sit in the hardest claim territory: real symptoms, thin objective findings. Wins come from pulmonary function testing, cognitive evaluation and a consistent specialist record.

Objective beats subjective in every claim. Build the file in months, not weeks: consistent specialist visits, diagnostic testing, and a documented medication history.
Building the claim file
- Get the job description into the treating physician’s hands — function is judged against work, not against wellness.
- Keep a symptom journal with bad-day specifics; generic ‘pain daily’ entries carry no weight.
- File early. Waiting months while ‘trying to push through’ reads as ability to work.
The denial pattern to expect
Expect the carrier to argue inconsistency — surveillance on a good day vs the claim file. Highly contested claims survive it when the medical record shows the pattern, not just the diagnosis.
Long COVID / post-viral fatigue claims are documentation contests: the diagnosis starts the file, the functional evidence wins it.
