About 40527: Full-thickness lip reconstruction with cross-lip flap
Reconstructs a full-thickness lip defect by transferring tissue from the opposite lip, typically when primary closure or a local flap is unsuitable.
This procedure rebuilds a full-thickness defect of the upper or lower lip using a flap of tissue transferred from the opposite lip. The flap remains attached to its donor site initially, creating a temporary connection between the lips. Plastic surgeons, otolaryngologists, and oral and maxillofacial surgeons may use this approach for defects after tumor removal or trauma when local tissue cannot provide adequate reconstruction. The service is generally performed in a facility setting.
Report the code when the operative documentation supports reconstruction with a cross-lip flap, rather than a different flap or graft method. Document the defect, donor and recipient sites, and the flap technique. The 90-day global period includes 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 are subject to the standard reduction. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

40527 billing questions
How does this differ from 40525?
40527 is for reconstruction using a cross-lip flap, which transfers tissue from the opposite lip. Choose 40525 when the documented reconstruction uses a different local flap technique.
Is the flap reported separately?
The cross-lip flap is the reconstructive method represented by 40527. Do not report a separate flap service for the same reconstruction.
Should modifier 50 be used when both lips are involved?
No. Modifier 50 is inappropriate for this code; document the cross-lip reconstruction and the donor and recipient sites.
When is an assistant surgeon payable?
Assistant-at-surgery payment is allowed only when the record documents medical necessity. Co-surgeons and team surgery are not permitted for this code.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
