Atrophy of salivary gland

This code signifies the pathological reduction in size and function of one or more salivary glands due to a decrease in cell size or number. This atrophy can lead to xerostomia (dry mouth) and impaired oral health.

Apply this code when documentation explicitly states atrophy of a salivary gland, such as the parotid, submandibular, or sublingual glands. This may be identified during imaging studies, biopsies, or clinical examination noting gland shrinkage and associated symptoms.

• Ensure documentation specifies "atrophy" rather than merely hypofunction or inflammation.
• Distinguish from congenital hypoplasia or aplasia, which are distinct conditions.
• Consider sequencing this code after any underlying systemic disease causing the atrophy, if applicable.
