Soft tissue surgery
About 21933: Deep back tumor excision, 5 cm or larger
Excision of a soft tissue tumor at least 5 cm across from beneath the back or flank fascia, including an intramuscular tumor.
This service removes a soft tissue tumor measuring 5 cm or more that lies beneath the fascia of the back or flank, including a tumor within muscle. A surgeon typically performs the excision in an operating room or an appropriately equipped outpatient setting. The code distinguishes a deep tumor from a subcutaneous lesion and distinguishes tumors at least 5 cm from smaller deep tumors.
Choose the code based on the tumor’s documented depth and size, not the length of the incision. The operative report should support the back or flank site, the tumor’s deep location, its dimensions, and the excision performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. 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% multiple-procedure reduction. Bilateral adjustment is inappropriate for this code. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

21933 billing questions
When should 21933 be selected instead of 21932?
Both describe excision of a deep soft tissue tumor of the back or flank. Select 21933 when the tumor is at least 5 cm; 21932 is for a smaller deep tumor.
How does 21933 differ from 21931?
21933 is for a deep tumor at least 5 cm across. 21931 describes excision of a subcutaneous back or flank lesion at least 3 cm across.
Can a biopsy and the excision be reported together?
A biopsy code describes sampling rather than removal of the tumor. The operative documentation should establish whether the service was a diagnostic biopsy or an excision; do not report both for the same work.
Does modifier 50 apply when tumors are removed on both sides?
CMS identifies bilateral adjustment as inappropriate for 21933. Do not use modifier 50 to claim a bilateral adjustment for this code.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
May 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.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
