CPT® Code 42235

The procedure described by CPT® Code 42235 involves the surgical repair of the anterior palate, which is the front portion of the roof of the mouth. This repair may utilize a vomer flap, a specific technique that involves the manipulation of tissue to close defects in the palate that may extend into the nasal or oral cavities. The anterior palate can be compromised due to various conditions, necessitating surgical intervention to restore its integrity and function. During the procedure, a flap of mucosal tissue, which can be either full-thickness or split-thickness, is elevated from the unaffected side of the palate. This flap is then rotated and sutured over the defect to effectively cover the area that requires repair. The vomer bone, which is a key structural component of the nasal septum, plays a significant role in this procedure. The surgical approach includes incising the palatal tissue over the vomer bone in an anterior to posterior direction, allowing for the elevation of the mucoperiosteum from one or both sides of the vomer. The vomer flap is subsequently advanced to cover the defect and is secured in place with sutures. Any remaining open areas are allowed to heal naturally through secondary intention, which is a process where the body heals the wound without surgical closure.
