CPT® Code 31240

The procedure described by CPT® Code 31240 refers to a surgical nasal and sinus endoscopy that specifically involves the resection of a concha bullosa. A concha bullosa is characterized by the abnormal enlargement of the middle turbinate, which is a structure within the nasal cavity that can become filled with air, leading to a condition known as pneumatization. This condition can obstruct normal airflow and ventilation of the sinus ostia, often resulting in recurrent episodes of sinusitis. During the procedure, a topical nasal decongestant may be applied to reduce swelling, and a local anesthetic with a vasoconstrictor is utilized to minimize bleeding and discomfort. An endoscope, a thin, flexible tube equipped with a camera and light, is inserted through the nostril to allow the physician to visualize the nasal cavity and the paranasal sinuses for any signs of disease or abnormalities. The surgical intervention involves the use of micro scissors to carefully resect the meatal surface of the middle turbinate while ensuring that the lateral lamella is preserved to maintain structural stability. Additionally, the procedure may include the resection of either the anterior or posterior portions of the middle turbinate, depending on the specific needs of the patient and the extent of the concha bullosa. This endoscopic approach is minimally invasive and aims to restore normal sinus function and alleviate symptoms associated with sinus obstruction.
