Question: I’m new to coding. When is it appropriate to append modifier 62? RCI Subscriber Answer: Modifier 62 (Two surgeons) applies to situations involving co-surgeons. In order to apply modifier 62, it is essential that your doctor collaborated with another surgeon, and that both are recognized as primary surgeons or co-surgeons. After verifying that your doctor was indeed a main co-surgeon, it is necessary to ensure that your doctor and the other surgeon jointly performed a procedure that is represented by a single CPT® procedure code. For Medicare, it’s necessary that each surgeon belongs to a distinct specialty; for instance, a collaboration between a podiatrist and a general surgeon. However, for non-Medicare carriers, the co-surgeons can be from the same specialty, typically with differing surgical skills. “When two surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associate add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons,” according to CPT®. “Each surgeon should report the co-surgery once using the same procedure code.” Final thought: Modifier 62 applies for only one primary procedure and its related add-on codes for each surgeon.
