CA-20 · OWCP Form
Attending Physician's Report
The full medical narrative from your treating doctor — diagnosis, causation, treatment plan, prognosis.
Who Files
Your treating physician.
When to File
Initial CA-20 at the start of treatment. Updated CA-20 (or supplemental medical reports) at major treatment milestones, before MMI determination, and any time OWCP requests one.
Deadline
OWCP typically requests CA-20 within 30 days of a request. Late submissions stall claim decisions.
What the Form Does
Provides OWCP examiners the medical evidence they need to accept the claim, authorize procedures, approve continued time off work, and eventually determine maximum medical improvement.
The Doctor's Role
We write CA-20 reports in the OWCP-examiner-friendly language that gets claims accepted on first review — explicit causation, diagnostic backup, treatment plan, prognosis.
Common Mistakes That Delay Your Claim
- ✕Submitting a CA-20 with vague causation ('possibly work-related')
- ✕Missing diagnostic studies that should have been ordered first
- ✕Failing to address every accepted condition in the report
