About 21558: Radical neck or anterior thorax tumor resection
Radical resection of a soft-tissue tumor in the neck or anterior thorax measuring at least 5 cm, typically for definitive oncologic treatment.
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.

21558 billing questions
How is 21558 different from 21554?
Both concern a deep neck tumor at least 5 cm, but 21558 is for radical resection. Use 21554 for the applicable deep-tumor excision when the documented operation is not a radical resection.
Does the tumor need to measure at least 5 cm?
Yes. This code is for a tumor measuring 5 cm or larger; 21557 is the related radical-resection code for tumors under 5 cm.
What documentation supports reporting 21558?
The operative report should identify the neck or anterior thorax site, tumor size, and the extent of the radical resection. Documentation should distinguish the operation from a limited excision or biopsy.
Can an assistant surgeon be reported?
CMS permits payment for an assistant at surgery with this code. Co-surgeon payment requires supporting documentation.
Can modifier 50 be used for bilateral tumors?
No. The code’s descriptor or anatomy makes modifier 50 inappropriate.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and related postoperative care for 90 days are included in the global period.
