About the B90 Code Range
These procedures make flat images of parts of the ear, nose, mouth and throat using radiation captured on a plate.
The fourth character identifies the sinuses, salivary glands, areas behind the nose and mouth, or mastoids. For salivary glands, it distinguishes the parotid and submandibular glands from other salivary glands, and right, left or both sides. The fifth character identifies high-osmolar, low-osmolar or other contrast material, or none. The sixth and seventh characters are always None.
The Index also lists sialography, imaging of the salivary glands.
