Orthopedic surgery
About 27640: Partial excision of tibial bone
Reports removal of a limited portion of tibial bone, commonly to clear localized diseased or infected bone such as in chronic osteomyelitis.
The surgeon removes a limited area of tibial bone, using techniques such as saucerization, craterization, or removal of a bone sequestrum. Orthopedic surgeons typically perform this operation for localized disease, including chronic osteomyelitis, in a hospital or ambulatory surgical setting. The operative report should identify the tibia, the portion removed, and the condition treated.
Report this code for partial bone removal, not a more extensive tibial tumor resection or a procedure directed at a benign bone cyst or tumor. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. For bilateral procedures, modifier 50 is paid at 150%. Assistant-at-surgery payment is barred by statutory restriction; co-surgeons require supporting documentation, and team surgery is not permitted.
