Mastoid Bone Surgery For Chronic Infection

South Dakota rates for HCPCS 69505

This is surgery on the mastoid bone behind the ear to remove infected bone and tissue, most often for a long-standing mastoid or middle-ear infection or a skin growth called a cholesteatoma. Some of the normal ear canal wall and structures are reshaped or removed to fully clear the disease, while certain hearing structures are preserved when possible. It is typically done under general anesthesia and may affect hearing on that side.
