Minor surgery
About 10121: Complicated subcutaneous foreign body removal
Reports incision and removal of a foreign object from subcutaneous tissue when extraction requires complicated dissection rather than a simple removal.
A clinician uses an incision and dissection to locate and remove a foreign object lodged in subcutaneous tissue, the tissue beneath the skin. Examples include embedded splinters, glass fragments, or metal. The code is appropriate when the removal involves complicated dissection; the object’s material or size alone does not establish that level. These procedures may occur in an office, emergency department, or other setting where a clinician treats the wound.
Document the object’s location and depth, the incision and dissection performed, and why removal was complicated. Use 10120 for a simple subcutaneous removal. Medicare includes related postoperative visits for 10 days in this minor procedure’s global period. When multiple procedures are performed in the same session, Medicare pays the highest-valued procedure in full and reduces the others to 50%. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeon and team-surgery billing are not permitted.

10121 billing questions
How does 10121 differ from 10120?
Both involve removal from subcutaneous tissue. Report 10121 when the extraction requires complicated dissection; use 10120 for a simple removal.
Does the type of foreign object determine whether removal is complicated?
No. Document the location, depth, dissection, and other circumstances supporting complicated removal; the object’s material alone does not establish the code level.
Can related postoperative visits be billed separately?
Related postoperative visits during the 10-day global period are included in 10121.
Can modifier 50 be appended for removal on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code.
Can an assistant or co-surgeon be reported?
Medicare does not pay an assistant at surgery for 10121, and co-surgeon or team-surgery billing is not permitted.
