About 40500: Full-thickness lip excision with primary closure
Reports removal of a full-thickness portion of the lip followed by direct closure, such as for a localized lesion requiring excision.
This service removes a full-thickness segment of the upper or lower lip and closes the resulting defect primarily, without using a flap for reconstruction. It may be performed for a localized lip lesion or neoplasm when the required excision extends through the lip. Plastic surgeons, otolaryngologists, and oral and maxillofacial surgeons may perform the operation in an operating room or an appropriately equipped outpatient surgical setting.
Choose this code when the operative report supports full-thickness excision and direct closure; document the site, extent of tissue removed, indication, and closure method. 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 50% multiple-procedure reduction. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery billing are not permitted.
