CPT® Code 31242

The procedure described by CPT® Code 31242 involves a surgical nasal and sinus endoscopy that specifically targets the destruction of the posterior nasal nerve (PNN) using radiofrequency ablation. This intervention is primarily indicated for patients suffering from chronic rhinorrhea, which is characterized by excessive mucus production due to a hyperactive PNN. This condition is often referred to as intractable vasomotor rhinitis. The goal of the procedure is to denervate the mucosa, thereby alleviating the nasal symptoms associated with this condition. During the procedure, a small endoscopic camera is utilized to provide visualization of the nasal passages, allowing for precise intervention. Local anesthesia is administered through the application of surgical cotton wads soaked in a decongestant and anesthetic, which are placed in various areas of the nasal cavity to ensure patient comfort. Following this, an intranasal anesthetic and vasoconstrictive agent are injected to further enhance the anesthetic effect. The procedure involves the introduction of a radiofrequency delivery device, which is designed to fit into the sphenopalatine regions and the inferior turbinate. This device applies low power radiofrequency energy to disrupt the nerve by generating heat in the targeted mucosal areas at the back of the nose. After the procedure is completed on one side, the instruments are removed, and the same steps are repeated on the opposite side to ensure comprehensive treatment.
