What this denial means, and to whom
$464.89 paid, $123.11 withheld
Billed $588.00. The payer paid $464.89, withheld $123.11. Of the $123.11 withheld, $123.11 is modelled as recoverable; less $31.00 to work it, that is $92.11 net. Claim lacks information. Read the accompanying RARC for what is missing. The modelled filing window closed 249 days ago. Confirm the contractual deadline before deciding whether a late submission or reconsideration is still open.
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.
