I am new to billing occupational therapy codes and received a partial denial for the 2nd and 3rd codes for 1 visit. Denial on claim is as follows: 59 – Charges are adjusted based on multiple surgery rules or concurrent anesthesia rules.

I am billing 97110, 97530, and 97535 with a GO modifier. The adjusted reimbursement is about 25% less than the agreed rate.

Is there anyway to get full payment? Should I be using modifier 59?
