What 23077 covers
This code describes definitive, en bloc removal of a tumor from the shoulder soft tissues using a radical approach, when the tumor measures less than 5 cm. An orthopedic oncologist or another surgeon treating musculoskeletal tumors typically performs the operation in a surgical setting, often for a suspected or confirmed malignancy such as a soft-tissue sarcoma. The resection includes surrounding tissue as needed for oncologic clearance, making it more extensive than simply removing a superficial mass or excising a deep tumor without a radical approach.
Select the code based on the radical extent of the resection and the tumor size, not size alone. The operative report should identify the shoulder site, tumor dimensions, tissue planes removed, and en bloc technique. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care for 90 days. When multiple procedures occur in one session, the highest-valued is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
