CPT® Code 42440

The procedure described by CPT® Code 42440 involves the excision of a submandibular gland, which is one of the major salivary glands located beneath the jaw. The submandibular glands are responsible for producing saliva, which aids in digestion and oral health. In this surgical procedure, one of the paired submandibular glands is surgically removed through an incision made in the upper neck, just below the mandible. This approach allows the surgeon to access the gland while minimizing damage to surrounding structures. During the excision, careful dissection is performed to free the gland from the surrounding tissue, with particular attention given to protecting the marginal mandibular branch of the facial nerve, which is crucial for facial movement. After the gland is successfully removed, a drain is typically placed in the surgical wound to prevent fluid accumulation, and the incision is then closed around the drain to facilitate healing. This procedure may be indicated for various conditions affecting the submandibular gland, including infections, tumors, or other pathologies that compromise its function or health.
