What this denial means, and to whom
Appealable · $144.00 modelled net of rework
The 835 reports CARC 109 on 7 Jun 2026, withholding $175.00 from the provider. Modelled recoverable $175.00, less an estimated rework cost of $31.00, leaves $144.00 net. The configured appeal window for this payer ends 4 Dec 2026, in 73 days. Recommended action: Not covered by this payer. Resubmit to the correct payer rather than appealing. 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.
