What 40810 covers

This service removes a lesion from the lining and underlying tissue of the oral vestibule, the space between the lips or cheeks and the teeth or gums. It may be performed by an oral and maxillofacial surgeon, dentist, or other qualified clinician in an office or surgical setting. A persistent or suspicious inner-lip or cheek lesion may be excised for treatment or tissue diagnosis; the specimen can be submitted for pathologic examination.

Choose this code when the documented work is excision in the vestibule and no repair is performed. If the operative note describes repair, compare the repair-specific codes in this family rather than reporting this code. Document the precise site, lesion and extent removed, and whether repair was performed. The service has a 10-day global period, which includes related postoperative visits during that period. 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% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; 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.

40810 billing questions

When should this code be used instead of 40808?

Use 40810 when the lesion is excised from the oral vestibule. Code 40808 describes biopsy rather than this excision service.

Does this code include closure of the excision site?

No repair is included in this code. If the operative note documents repair, compare the repair-specific vestibular lesion excision codes.

Can modifier 50 be reported for lesions on both sides?

No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this code.

Are postoperative visits separately reported during the global period?

Related postoperative visits during the 10-day global period are included in the procedure.

Can an assistant surgeon or co-surgeon be paid?

Medicare does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.

Is examination of the removed tissue included?

The code represents removal of the lesion, not the pathologist's examination. A pathology service may be reported separately when performed.

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.
