About 40520: Full-thickness lip excision with local flap
Reports full-thickness removal of lip tissue when the resulting defect is reconstructed with a local flap, such as for an excised lip lesion.
This operation removes the full thickness of part of the lip and uses nearby lip tissue to reconstruct the defect. It may be performed for a lesion, including a lip cancer, when excision leaves a defect requiring flap repair. Plastic surgeons, otolaryngologists, and oral and maxillofacial surgeons may perform it in an operating room or another surgical setting appropriate to the procedure.
Report 40520 when the operative record supports full-thickness excision and local-flap reconstruction. Document the lip site, extent of tissue removed, and reconstruction performed; a superficial shave or excision closed without a flap describes a different service. The procedure has a 90-day global period, including the day-before preoperative visit and related postoperative care. When other procedures occur 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, and co-surgeon and team-surgery billing are not permitted.

40520 billing questions
When should 40520 be chosen over a code for lip excision without reconstruction?
Use 40520 when the full-thickness lip defect is reconstructed with a local flap. Excision without reconstruction is represented by a different code, such as 40530.
Does this code include the local-flap repair?
Yes. The service includes local-flap reconstruction of the defect created by the full-thickness lip excision; do not report the included repair again as a separate service.
What operative details support reporting 40520?
Document the lip site, full-thickness extent of the excision, and use of a local flap to reconstruct the defect. The record should make clear that this was more than a superficial shave or primary closure.
Can modifier 50 be reported for excisions on both sides of the lip?
No. Modifier 50 is inappropriate for this code, even when the operative work involves both sides.
How does the 90-day global period affect postoperative visits?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period. The global period follows the operation, not each subsequent visit.
Can an assistant or co-surgeon be billed for this operation?
Medicare does not pay an assistant at surgery for 40520. Co-surgeon and team-surgery billing are also not permitted.
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.
