What 40814 covers
Code 40814 describes excision of a lesion from the mucosa and submucosa of the mouth vestibule, followed by complex repair. The vestibule is the space between the lips or cheeks and the teeth or gums; examples include the inner lip or cheek lining. Oral and maxillofacial surgeons, otolaryngologists, and other surgeons may perform the procedure in an office, ambulatory surgery center, or hospital. A specimen may be sent for pathologic examination, but the operative service is selected by the excision and repair performed, not by the final diagnosis.
Choose this code when the operative report supports a complex repair, rather than no repair or simple repair. Document the lesion’s site, the excision performed, and the repair technique and complexity. Medicare assigns a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
