What this denial means, and to whom

Member Registrar Provider billing Denial analyst Director Payer review

What were we paid, and what can we still pursue?

$46.02 paid, $15.98 withheld

Billed $62.00. The payer paid $46.02, withheld $15.98. Of the $15.98 withheld, $15.98 is modelled as recoverable; less $31.00 to work it, that is -$15.02 net. Not covered by this payer. Resubmit to the correct payer rather than appealing. On these estimates the work costs more than it returns, which is a judgement about this model's figures rather than a rule.

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.
