What 21558 covers

This service covers radical removal of a soft-tissue tumor, such as a sarcoma, in the neck or anterior thorax when the tumor is at least 5 cm. It represents a more extensive oncologic resection than a limited excision or diagnostic biopsy. Head and neck or surgical oncology surgeons commonly perform it in an operating room, with the operative approach and extent guided by the tumor’s location and treatment plan.

Report the code when the operative record supports radical resection and identifies the anatomic site, tumor size, and extent of removal. The service has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. For other procedures performed in the same session, the highest-valued procedure is paid in full and additional procedures are subject to the standard 50% multiple procedure reduction. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted. Modifier 50 is inappropriate for this code.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
