Hypertrophy of salivary gland

This code signifies an abnormal enlargement or overgrowth of one or more salivary glands. This hypertrophy can affect any of the major salivary glands (parotid, submandibular, sublingual) and may be unilateral or bilateral. It often presents as a palpable swelling in the neck or jaw area.

Use this code when documentation specifies a diagnosis of salivary gland hypertrophy, without evidence of inflammation (sialadenitis), tumor, or stone (sialolithiasis). It is appropriate for conditions like benign masseteric hypertrophy affecting the parotid gland, or other non-inflammatory, non-neoplastic glandular enlargement. Supporting documentation should clearly state "hypertrophy" of the salivary gland.

• Differentiate from sialadenitis (inflammation of the salivary gland) which would be coded elsewhere.
• Ensure documentation rules out neoplastic processes; if a tumor is present, a more specific neoplasm code is required.
• Do not use for salivary gland cysts or mucoceles, which have distinct codes.
