Disturbances of salivary secretion

This code signifies a range of conditions affecting the normal production and flow of saliva, encompassing both excessive (sialorrhea/ptyalism) and diminished (xerostomia/hyposalivation) secretion. These disturbances can lead to various oral health issues, discomfort, and impact digestion. It specifically excludes dry mouth not otherwise specified, which has its own code.

Use this code when documentation clearly indicates a diagnosed disturbance in salivary secretion, such as hypersalivation, ptyalism, or hyposalivation, that is not simply "dry mouth NOS." This code is appropriate for conditions like Sjogren's syndrome manifestations affecting salivary glands, medication-induced sialorrhea, or radiation-induced hyposalivation, provided the specific cause is also coded.

• Do not use this code for "dry mouth NOS"; refer to the Excludes2 note for the appropriate code.
• Always code the underlying cause or associated condition (e.g., Sjogren's syndrome, medication adverse effect) in addition to this code, if known.
• Ensure documentation specifies whether the disturbance is an excess or deficiency of salivary secretion for accurate clinical picture, though this code covers both.
