What this denial means, and to whom
$88.00 withheld, nothing paid
Billed $88.00. The payer paid $0.00, withheld $88.00. Of the $88.00 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 5 Mar 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.
