What 40819 covers

Code 40819 represents surgical removal of a lip or cheek fold, commonly a labial or buccal frenum, rather than release by incision alone. An oral and maxillofacial surgeon, oral surgeon, or other qualified surgeon may perform it for a restrictive or symptomatic fold in the oral vestibule. The operative note should identify the fold and site, explain the reason for excision, and describe the tissue removed.

Select this code when the fold itself is excised; a simple frenum incision is a different service, and a discrete mucosal lesion is coded according to the lesion procedure performed. The major-surgery 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 at 50%. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment requires documented medical necessity; 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.

40819 billing questions

How is excision different from a frenum incision?

Use 40819 when the lip or cheek fold is excised. Code 40806 describes an incision of the labial frenum, not excision of the fold.

Should modifier 50 be reported for folds on both sides?

No. Modifier 50 is inappropriate for 40819 under the CMS bilateral rule.

What postoperative care is included?

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

Can an assistant surgeon be paid for this procedure?

Can co-surgeons or a surgical team report this service?

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.
