About the 097 Code Range
These procedures widen an opening or inner passage in the right or left Eustachian tube (auditory tube) or nasopharynx (upper throat behind the nose).
The fourth character identifies the body part, including which Eustachian tube is treated. The fifth distinguishes open exposure from entry through a puncture, small incision, or natural or artificial opening, with or without a scope. The sixth records an intraluminal device, meaning one inside the passage, or no device. The seventh is always No Qualifier.
