What this denial means, and to whom
Appealable · $20.44 modelled net of rework
The 835 reports CARC 16 on 12 Apr 2026, withholding $51.44 from the provider. Modelled recoverable $51.44, less an estimated rework cost of $31.00, leaves $20.44 net. The configured appeal window for this payer ends 9 Oct 2026, in 17 days. Recommended action: Claim lacks information. Read the accompanying RARC for what is missing. Confirm the contractual deadline and any exception, reconsideration or correction route with the payer before closing the case.
From: Denial derivation: root cause, appealability, the recoverable amount net of an estimated rework cost, and a filing deadline derived from the denial date.
Limits: The deadline and the recoverable amount are application estimates. The deadline is the denial date plus a configured per-payer window, not a term read from the payer's contract or an appeal notice, and the recoverable figure is a model rather than a promise of payment. Confirm both against the policy before relying on them.
