Denial Prevention & Appeals
A denial is the expensive recovery of a front-end miss. Prevent first; appeal with evidence.
Front-end prevention (before the claim leaves)
- Eligibility + benefits verified — active coverage, therapy benefit, visit cap.
- Authorization in hand if required, with enough visits.
- Units correct under the 8-minute rule (see
../therapy-billing-and-units/SKILL.md).
- Modifiers correct (GP/KX/59) and supported by documentation.
- Documentation establishes medical necessity and skilled care (see
../defensible-documentation/SKILL.md).
Denial triage (root cause → fix)
| Denial signal | Likely root cause | Fix |
|---|
| Units / frequency | 8-minute-rule variant, cap exceeded | Recount; check payor variant + auth |
| Modifier / NCCI edit | Missing/wrong GP/KX/59 | Match modifier to discipline/threshold/distinct service |
| Medical necessity | Boilerplate / no skilled justification | Documentation, not appeal language, is the fix |
| Eligibility / auth | Front-end miss | Verify before re-submission |
The appeal
Lead with the documentation that already exists — the note is the evidence. Cite the specific clinical reasoning, the POC goal, and (if threshold) the KX attestation basis. A late or boilerplate appeal loses.
Verify-at-use
- Each payor's denial reason codes, edits, and appeal windows differ and change — confirm against the payor's current policy before re-billing or appealing.
