CPT® Code 40720

The CPT® Code 40720 refers to the plastic repair of a cleft lip and nasal deformity, specifically a secondary procedure that involves the recreation of the defect followed by its reclosure. Cleft lip is a congenital condition characterized by a split or opening in the upper lip, which can also affect the nasal structure. This condition arises from improper migration of embryonic connective tissue during the formation of the palate, leading to disfigurement. Cleft lip and associated nasal deformities can present as either unilateral (one side) or bilateral (both sides), and each case is unique, necessitating tailored surgical planning and techniques. In a secondary repair, the surgeon reopens the lip and nasal area along the original incision lines from the initial repair. This process involves the release and excision of scar tissue, followed by the undermining of underlying tissues to facilitate a tension-free closure. The surgical approach includes identifying anatomical landmarks, advancing or rotating previously created flaps to restore the continuity of the orbicularis muscle, and correcting any nasal deformities by freeing the nasal skin from the underlying skeletal structure. The procedure concludes with the repositioning of the cartilaginous components of the nose and the careful closure of all skin incisions using fine sutures or skin adhesive to ensure optimal healing and aesthetic results.
