CPT® Code 40843

The procedure described by CPT® Code 40843 refers to a bilateral vestibuloplasty, which is a surgical intervention aimed at modifying the vestibule of the mouth. The vestibule, also known as the buccal or oral cavity, encompasses the mucosal and submucosal tissues of the lips and cheeks, while excluding the dentoalveolar structures. The primary objective of vestibuloplasty is to restore the height of the alveolar ridge, which is the bony ridge in the upper and lower jaws that contains the sockets for teeth. This procedure is particularly beneficial for patients with congenital conditions such as cleft lip and/or palate, as well as other facial deformities, where the soft tissue and underlying bone may require reshaping to achieve both aesthetic and functional improvements. In addition, vestibuloplasty can be performed on edentulous patients who have a shallow vestibular sulcus, with the goal of deepening the vestibule to enhance the fit of dentures or dental implants. The surgical technique involves making an incision in the mucosa located in the sulcus between the lip or cheek and the alveolar ridge, allowing for the separation of connective tissue and muscle attachments. Following the incision, the buccal or labial tissue is repositioned and sutured in its new location, or a graft may be utilized to cover the incision site. This procedure is categorized as bilateral when it involves both sides of the mouth, distinguishing it from unilateral vestibuloplasty, which is coded separately. Overall, vestibuloplasty is a critical procedure in oral and maxillofacial surgery that facilitates improved oral function and aesthetics for various patient populations.
