What 40806 covers

This procedure releases a restrictive labial frenum by incising the tissue fold between the inner surface of the upper or lower lip and the gum. It may be performed by an oral surgeon, dentist, or other qualified clinician when the labial attachment is being released; it is distinct from surgery on the lingual frenum beneath the tongue. The record should identify the lip site and describe the frenum release performed.

Select this code for incision and release, not for removal of a mouth lesion or excision of a lip or cheek fold. Document the clinical indication, anatomical site, and work performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. 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 multiple procedure reduction. 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.

40806 billing questions

How does this differ from a lingual frenum procedure?

This code is for incision and release of a labial frenum connecting the inner lip to the gum. Procedures on the frenum beneath the tongue are coded separately.

When would 40819 be more appropriate?

Choose 40819 when the documented service is excision of a lip or cheek fold. This code describes incision and release of a labial frenum.

Should modifier 50 be appended for upper and lower lip sites?

No. CMS identifies bilateral adjustment as inappropriate for this code. Document the treated site or sites without using modifier 50.

What documentation supports reporting this code?

Document the restrictive labial frenum, whether it is associated with the upper or lower lip, the clinical reason for release, and the incision and release performed.

How does the 0-day global period affect same-day services?

Same-day preoperative and postoperative care is included in the procedure. If other procedures occur in the same session, the standard multiple procedure reduction applies.

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.
