About 40530: Full-thickness lip excision with free-flap reconstruction
Reports full-thickness removal of lip tissue with free-flap reconstruction, commonly for a lesion or cancer defect requiring tissue transfer.
This service removes a full-thickness portion of the lip and reconstructs the defect with a free flap. It may be performed by a plastic surgeon, oral and maxillofacial surgeon, or head and neck surgeon when excision of a lesion, such as a lip cancer, leaves a defect requiring transferred tissue. The operative report should describe the extent of lip removed and the reconstructive method.
Report the code for the combined excision and reconstruction, rather than separately coding routine closure included in that service. The 90-day global period 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 other procedures are subject to the standard multiple procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.

40530 billing questions
How does this differ from 40510?
40510 describes full-thickness lip excision that does not require reconstruction. Use 40530 when the excision is accompanied by the free-flap reconstruction represented by this code.
Can the reconstruction be billed separately?
The code represents the excision with its specified free-flap reconstruction. Do not separately report routine reconstructive work that is included in that service.
Should modifier 50 be appended for both sides of the lip?
No. CMS identifies bilateral adjustment as inappropriate for this code; do not use modifier 50.
Can an assistant surgeon or co-surgeon be billed?
Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
What documentation supports reporting this code?
Document the full-thickness lip tissue removed, the defect created, and the free-flap reconstruction performed. The operative report should make clear that the service included both excision and reconstruction.
