Which modifier would you use for a procedure done by a different physician within the postoperative period?

Using the -79 modifier is appropriate for indicating that a procedure was performed by a different physician during the postoperative period of a previous procedure. This modifier specifically signifies that the subsequent procedure is not related to the original surgery, which is essential in preventing confusion and ensuring accurate billing.

When a patient undergoes a surgical procedure, the postoperative period is defined as the time following that surgery during which certain follow-up actions and care are associated with the initial procedure. If another physician performs a procedure unrelated to the initial surgery within this timeframe, applying the -79 modifier clarifies that the two procedures are distinct and justifies the reimbursement for the services provided by the second physician.

In summary, the -79 modifier effectively communicates that the subsequent procedure is unrelated to the original procedure’s postoperative care, allowing for proper billing and documentation practices in CPT coding.
