Sinus Surgery With Sphenoid Tissue Removal

Colorado rates for HCPCS 31288

A thin scope is passed through the nostril to open the sphenoid sinus, an air pocket sitting deep behind the nose, and diseased tissue such as polyps or thickened lining is taken out from inside it. It is used for long-standing sinus disease or blockage that has not cleared with medicine. Everything is done through the nose, so there are no cuts on the face.
