Surgical biopsy
About 21550: Deep neck or thorax soft-tissue biopsy
Reports a deep soft-tissue biopsy in the neck or thorax when tissue is sampled to establish a diagnosis rather than remove the mass.
This code describes surgical sampling of deep soft tissue in the neck or thorax for diagnostic evaluation, such as obtaining tissue from a deep mass. A surgeon, otolaryngologist, or thoracic surgeon may perform the procedure in an office-based setting or hospital operating room, depending on the location and access required. The service is a biopsy, not removal of a neck lesion or tumor as definitive treatment.
Choose the code when the operative record supports a deep soft-tissue biopsy in the specified anatomic region. Document the site, depth, approach, and diagnostic purpose; codes for excising neck lesions or tumors are selected when the tissue is removed rather than sampled. The 10-day global period includes related postoperative visits during that period. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this descriptor and anatomy. CMS does not pay an assistant at surgery for this code, and co-surgeon and team-surgery reporting are not permitted.

21550 billing questions
How does this differ from a neck tumor excision code?
Use 21550 when the procedure samples deep soft tissue for diagnosis. When the surgeon removes a neck lesion or tumor, consider the applicable excision code instead.
Can modifier 50 be used for biopsies on both sides?
No. Modifier 50 is inappropriate for this descriptor and anatomy.
Are related postoperative visits separately paid during the global period?
Related postoperative visits during the 10-day global period are included in the procedure payment.
How is this code affected when another procedure is performed in the same session?
The highest-valued procedure is paid in full; other procedures in the same session are subject to the standard multiple-procedure reduction.
Can an assistant surgeon or co-surgeon be reported?
CMS does not pay an assistant at surgery for this code. Co-surgeon and team-surgery reporting are not permitted.
