Where this comes up
This is denial-workbench territory. A remit posts with a CARC/RARC, the biller decides whether to rebill, appeal, or write off, and the appeal packet has to cite the chart, the order, and the payer's own policy language. Recurring patterns trace back to an upstream workflow gap.
Full definition
What it is in practice
CMS Medicare Appeals describes the five levels with filing deadlines and amount-in-controversy thresholds. Each level has its own decision-maker and timeline.
How it shows up in your practice
Most denials are resolved at Level 1 (Redetermination) or Level 2 (Reconsideration). ALJ hearings are slow but high-success for documented cases. Track each appeal's stage and statutory deadline.
