What 40816 covers

This service removes a lesion involving the mucosa and submucosa of the oral vestibule, the space between the lips or cheeks and the teeth or gums, and closes the resulting defect with a full-thickness skin graft. Oral and maxillofacial surgeons, otolaryngologists, and other surgeons who treat oral lesions may perform it. The operative note should identify the vestibular site, lesion excision, defect, and graft reconstruction.

Report this code when the lesion is excised and the defect is closed with a full-thickness skin graft, rather than with no repair or routine closure. Documentation should support the graft technique and the work performed. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur 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; assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

40816 billing questions

How does 40816 differ from 40810, 40812, and 40814?

40816 describes lesion excision with full-thickness skin graft closure. The neighboring codes distinguish excision without repair or with simple or complex repair; the operative documentation should support the closure method reported.

Is a biopsy code appropriate when the lesion is removed?

40808 describes biopsy of a vestibular mouth lesion. When the lesion is excised and the defect is reconstructed with a full-thickness skin graft, report the excision service rather than treating the work as biopsy alone.

What documentation supports reporting 40816?

Document the oral vestibule site, lesion excision, resulting defect, and use of a full-thickness skin graft for closure.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

Can modifier 50 or an assistant-at-surgery claim be used?

Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery for this service.

How are other procedures in the same session affected?

Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50%. Co-surgeons and team surgery are 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 indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
