About the 0C7 Code Range
These procedures widen an opening or passage in the right or left parotid duct, pharynx (throat), or larynx (voice box). They do so by stretching the passage or cutting part of its opening or wall.
The fourth character identifies the body part and distinguishes the right and left parotid ducts. The fifth records an open incision, a puncture or small incision, or entry through a natural or artificial opening. The latter approaches include options with a scope. The sixth distinguishes an intraluminal device from no device. The seventh is always No Qualifier.
