CPT® Code 42450

The procedure described by CPT® Code 42450 refers to the excision of the sublingual gland, which is a salivary gland located beneath the tongue. This gland plays a crucial role in the production of saliva, which aids in digestion and oral health. During the excision, Wharton's duct, which is the duct associated with the submandibular gland, is cannulated prior to the dissection of the tissue. This step is essential as it allows for the identification and protection of the duct during the surgical procedure. The surgeon makes an incision medial to the sublingual salivary gland, carefully dissecting the gland from the surrounding tissues. It is important to protect adjacent structures, including the submandibular duct and the lingual nerve, to prevent complications. Once the gland is successfully removed, the surgical wound is repaired in layers to promote proper healing and minimize scarring. This procedure may be indicated in cases of glandular disease, obstruction, or other pathological conditions affecting the sublingual gland.
