The Playbook · Clinical Validation
They agreed your coding was perfect. They denied it anyway.
The letter says the code assignment isn't in dispute. The diagnosis underneath it is. Answer that with a coding appeal and you defend ground the payer already gave up.
- For CDI, HIM and denials teams: how to tell a coding downgrade from a clinical validation denial in the letter itself, and who should own each.
- Covers the five diagnoses reviewers target most (A41, J96, N17, E43, I21.A1), a criteria ledger by payer, and a five-move appeal a clinician signs.
The Playbook, section by section
Sort first. Target five. Write the reasoning down.
A short playbook, because the failure is specific.
The fork.
Coding downgrade or clinical validation: what each letter cites and who owns it.
Five targets
Sepsis, respiratory failure, AKI, severe malnutrition and type 2 MI, with the documentation anchor for each.
Silent downgrades.
A weekly DRG billed vs. paid report that finds the denials no letter announced.
The criteria ledger.
Track whose clinical criteria each payer applies, then move it into the contract.
The clinician's appeal.
Five moves, from accepting the concession to defending the bedside standard.

Why RapidClaims
The anchors belong in the note before the bill drops.
RapidClaims flags the five target diagnoses pre-bill when the physician's note lacks the supporting indicators, so CDI can query while the patient is still in the building.
