What 40840 covers

This procedure deepens the anterior vestibule by releasing and repositioning soft tissue, creating more space between the lip or cheek and the alveolar ridge. Oral and maxillofacial surgeons commonly perform it for a shallow or tethered anterior vestibule when reconstruction is needed, including in patients with an inadequate denture-bearing area. It is generally performed in a surgical setting, with the operative report identifying the treated site and extent of reconstruction.

Choose this code for anterior vestibuloplasty; posterior procedures, reconstruction of the entire arch, or complex work including ridge extension belong to other codes in the family. Medicare payment is restricted to specific circumstances, so documentation should establish the clinical reason for reconstruction and describe the work performed. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and each other procedure is paid at 50%. Assistant-at-surgery payment may be made; co-surgeons and team surgery are not permitted. Modifier 50 is inappropriate.
