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.
