Surgical Opening Of Several Sinuses, One Side

Montana rates for HCPCS 31090

Surgically opens several of the air-filled sinus cavities on one side of the face, which may include those behind the forehead, in the cheek, between the eyes, and deep behind the nose, so they can drain and ventilate again. It is done for long-standing sinus disease, infection, or a growth that has not settled with medicines. Treating several sinuses in one operation is what makes this the more extensive version.
