Postoperative period

“Can someone please clarify the postoperative global period for a percutaneous flexor tenotomy for flexible hammertoes? I thought the postop global for CPT 28010 was ten days. I discovered that it is 90 days! Is it really the same as a bunion correction? I performed an in office flexor tenotomy successfully on one foot and now the patient requests correction for the other foot. I understand how a longer global period would discourage so called “serial surgeries” for higher reimbursements for multiple procedures on one foot. But on the opposite foot as well?”
