Surgery

About 21930: Subcutaneous back mass excision under 3 cm

Reports excision of a subcutaneous soft-tissue mass on the back or flank when the mass is smaller than 3 cm.

This service removes a small soft-tissue mass from the subcutaneous layer of the back or flank. A surgeon typically makes an incision and dissects the mass from surrounding tissue; a small lipoma is a familiar example. The code is for a mass beneath the skin, not a lesion confined to the skin or a sample taken only for diagnosis. It may be performed in an office procedure room or a surgical facility.

Select this code when the documented site is the back or flank, the mass is subcutaneous, and its size is under 3 cm. The operative report should support the location, tissue plane, dimensions, and excision performed. This major surgery has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate; Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery billing are not permitted.

21930 billing questions

When should I report 21930 instead of 21931?

How does 21930 differ from 21932?

21930 describes a subcutaneous mass under 3 cm. 21932 is for a deeper, subfascial or intramuscular mass under 5 cm.

Can I use 21930 when the surgeon only biopsies the mass?

What documentation supports reporting 21930?

Document the back or flank location, the subcutaneous tissue plane, the mass dimensions, and that the mass was excised.

What global and multiple-procedure rules affect 21930?

It has a 90-day global period that includes the day-before preoperative visit and 90 days of related postoperative care. In the same session, the highest-valued procedure is paid in full and other procedures are paid at 50%.

Can I report an assistant, co-surgeon, or team surgeon with 21930?

Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
