What this denial means, and to whom
Appealable · $0.00 modelled net of rework
The 835 reports CARC 50 on 26 Apr 2026, withholding $0.00 from the provider. Modelled recoverable $0.00, less an estimated rework cost of $31.00, leaves $0.00 net. The configured appeal window for this payer ends 23 Oct 2026, in 31 days. Recommended action: Not deemed medically necessary. Appeal with clinical documentation. 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.
