What this denial means, and to whom
$439.02 paid, $205.98 withheld
Billed $645.00. The payer paid $439.02, withheld $205.98. Of the $205.98 withheld, $205.98 is modelled as recoverable; less $31.00 to work it, that is $174.98 net. Claim lacks information. Read the accompanying RARC for what is missing. To pursue the withheld amount, quote the payer's own claim number from the remittance and the adjudication date 2 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.
