Ingrown Nails

“Outpatient surgery was performed at a surgical center. We billed Blue Cross for CPT 11750 (T5) and CPT 11730 x 3 (T2, T7, T9). But they only paid CPT 11750. And the denial reasons are: ARV – Quantity billed exceeds CMS medically unlikely edits (MUE) limit. Rebill within MUE limit if appropriate. 222 – Exceeds the contracted maximum number of hours/days/units by this provider for this period. This is not patient specific. Usage: refer to the 835 healthcare policy identification segment, if present. So my question is, what is the limit to bill for ingrown nail surgery?”
