What 40844 covers

This procedure rebuilds the oral vestibule—the space between the cheek or lip and the gum—using a mucous membrane graft, including obtaining the graft. Oral and maxillofacial surgeons and other qualified surgeons may perform it when tissue loss or scar contracture has reduced vestibular depth, such as after trauma or prior surgery. The reconstruction may restore the oral lining and improve the area’s shape for function or prosthetic support.

Select the code that matches the documented reconstructive technique and graft work; distinguish this service from vestibular reconstruction using another graft type or a different approach. The operative report should identify the affected site, reason for reconstruction, graft type and source, whether the graft was obtained during the procedure, and the reconstructive work performed. CMS lists restricted coverage, so payment is limited to specific circumstances. The day-before preoperative visit and 90 days of related postoperative care are included in the 90-day global period. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures are subject to the standard reduction. Assistant-at-surgery payment may be made; co-surgeon and team-surgery billing are not permitted. Modifier 50 is inappropriate for this descriptor and anatomy.

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.

40844 billing questions

How is 40844 distinguished from other vestibule reconstruction codes?

40844 describes reconstruction with a mucous membrane graft, including obtaining the graft. Choose among related codes according to the graft and reconstructive work documented in the operative report.

What documentation supports reporting 40844?

Document the vestibular site and defect, the reason for reconstruction, the graft type and source, whether it was obtained during the procedure, and the reconstructive steps. CMS payment is restricted to specific circumstances.

Are routine postoperative visits separately reported?

Related postoperative care during the 90-day global period is included, as is the day-before preoperative visit.

Can another procedure be reported during the same session?

A separately performed procedure may be reported when supported by the record. CMS applies the standard multiple-procedure reduction to other procedures performed in the same session.

Can modifier 50 be used for reconstruction on both sides?

No. CMS identifies modifier 50 as inappropriate for this descriptor and anatomy.

Can an assistant surgeon be reported?

CMS indicates assistant-at-surgery payment may be made. Co-surgeon and team-surgery billing 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.
