What this denial means, and to whom
$897.00 withheld, nothing paid
Billed $897.00. The payer paid $0.00, withheld $897.00. Of the $897.00 withheld, $0.00 is modelled as recoverable; less $31.00 to work it, that is $0.00 net. Exact duplicate. Confirm it is a duplicate rather than a distinct service on the same day. To pursue the withheld amount, quote the payer's own claim number from the remittance and the adjudication date 23 Aug 2026, and confirm the route and deadline with the payer.
From: 835 CLP amounts and CAS adjustments on this claim; the denial derivation for the modelled recoverable amount and filing window.
Limits: Patient responsibility reported on an 835 is not revenue. This application cannot say whether the practice billed it, whether the patient paid, or whether a secondary payer covered it — those live in a billing system it does not read. The recoverable figure and the deadline are estimates, not a payer commitment.
