CPT® Code 31296

Nasal/sinus endoscopy, surgical, with dilation (CPT® Code 31296) refers to a minimally invasive procedure aimed at treating chronic sinusitis characterized by obstruction of the frontal sinus ostium, which is the opening that allows drainage from the frontal sinus into the nasal cavity. This procedure involves the use of an endoscope, a thin, flexible tube equipped with a camera and light, which is inserted through the nostrils to visualize the nasal passages and sinuses. The primary goal of the endoscopic dilation is to restore normal sinus drainage by widening the obstructed ostium. This is achieved through the inflation of a small balloon that compresses the surrounding mucosa and displaces any bony structures that may be contributing to the blockage. Prior to the procedure, a topical nasal decongestant and local anesthetic with a vasoconstrictor may be applied to minimize discomfort and reduce bleeding. The procedure is particularly beneficial for patients suffering from chronic sinusitis who have not responded to medical management, as it can significantly improve sinus drainage and alleviate symptoms associated with sinus obstruction.
