Modifier 50 for ATT?

Modifier 50 for ATT?

June 6, 2019


My doctor did two adjacent tissue transfers, on the each leg of the patient. The ATT on the left leg was 6sq cm and the one on the right leg was 9sq cm. He wants to bill 14020 with modifier 50, but I don’t think that is correct. Help.


CPT code 14020 has an indicator of “0” for bilateral procedures, which means that the bilateral procedure concept does not apply and this code cannot be billed with modifier 50. You may want to check with the payor to see how they wish the codes to be reported (14020 with 2 units; 14020, 14020-76; 14020, 14020-59 (X{SEPU})..
