Endoscopic Sphenoid Sinus Balloon Dilation

Maine rates for HCPCS 31297

This is an endoscopic procedure that widens the drainage opening of the sphenoid sinus, one of the sinus cavities located behind and above the nasal passages, using a small balloon rather than cutting away tissue. A thin scope with a camera guides the balloon into place through the nostril. It's used to relieve chronic sinus blockage and improve drainage.
