Modifier 80 vs. 82

Question:

What is the difference between modifier 80 and modifier 82 when a physician is acting as an assistant during surgery?

Answer:

While both modifier 80 and modifier 82 are used when a physician is actively participating as an assistant to a primary surgeon during a surgical procedure, the modifier 82 is used in teaching or university hospitals that have approved Graduate Medical Education (GME) programs for residents. In these teaching hospitals, there must be documentation indicating that no qualified resident was available to assist to allow for another physician to act as the assistant surgeon, and then modifier 82 is appended to that assistant surgeon.
