Reconciling a contractor-priced payment for 77423 Copy link
There is no national allowed amount for 77423, so every reconciliation of this line runs against the MAC fee schedule that was in force for the date of service rather than against a national baseline.
What to check
- Compare the paid amount against the MAC fee schedule in force for the date of service; there is no national allowed amount here to reconcile against.
- Only a technical-component amount is published for this code, so a professional charge billed on it has no fee-schedule amount behind it.
- Check for documentation on file before appealing an assistant-at-surgery denial: payment on the -80 or -AS line is restricted for this procedure unless medical necessity is established.
- Reprice the line against the release, locality, setting, modifier and participation status that applied to the date of service before treating any difference as an underpayment.
