UNDERSTANDING HOW TO USE MODIFIER 79
Per the Current Procedure Terminology® (CPT®) manual, the descriptor of modifier 79 is:
• "Unrelated procedure or service by the same physician during the postoperative period."

When a patient has surgery performed, there is a postoperative period -- a period after the surgery has been performed when additional surgical care related to the initial surgery is considered already covered (and paid for) by the allowance provided for the initial surgery. The postoperative period can be zero or 10 days (minor surgical procedure) or 90 days (major surgical procedure).

When the 79 modifier is used, a new postoperative period for the second surgical procedure begins. Additionally, the remainder of the postoperative period of the original surgery is still applicable.
