About 21932: Deep back soft tissue tumor excision under 5 cm
Reports excision of a deep soft tissue tumor of the back or flank when the tumor measures less than 5 cm.
This service removes a soft tissue tumor beneath the superficial fascia in the back or flank, such as an intramuscular mass, with a size under 5 cm. A surgeon typically performs the excision in an operating room or, when appropriate, an office procedure setting. The operative note should identify the back or flank site, describe the tumor’s depth and size, and document the excision performed. A limited tissue sample for diagnosis is a biopsy service rather than this excision.
Select this code for the deep location and size, not simply because a back mass was removed. The service has a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. The descriptor and anatomy make modifier 50 inappropriate. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

21932 billing questions
How is this distinguished from a superficial back mass excision?
This code is for a tumor beneath the superficial fascia. A tumor confined to subcutaneous tissue is reported with the applicable superficial back or flank excision code.
When should a back mass be reported as a biopsy instead?
Use a biopsy code when the procedure obtains a tissue sample for diagnosis rather than excising the tumor. The operative note should make clear whether the surgeon sampled the mass or removed it.
How does the 5 cm threshold affect code selection?
This code describes a deep back or flank tumor under 5 cm. A deep tumor measuring 5 cm or more falls in the corresponding larger-size code.
Can modifier 50 be used for bilateral back tumors?
No. CMS identifies bilateral adjustment as inappropriate for this descriptor and anatomy, so modifier 50 is not appropriate.
What postoperative care is included in the global period?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or another surgeon be reported?
An assistant at surgery may be paid. CMS does not permit co-surgeons or team surgery for this code.
