Chronic enlargement of unspecified lacrimal gland

This code signifies a persistent, non-acute increase in the size of a lacrimal gland, the gland responsible for tear production. It indicates an ongoing, rather than sudden, swelling or hypertrophy of this gland, without specifying which eye is affected.

Use this code when documentation indicates a long-standing or recurring enlargement of the lacrimal gland, such as in cases of chronic dacryoadenitis or idiopathic orbital inflammation affecting the lacrimal gland. Supporting documentation should clearly state "chronic" and "enlargement" or "hypertrophy" of the lacrimal gland.

• Do not use for acute lacrimal gland inflammation; refer to codes for acute dacryoadenitis.
• If the laterality (right or left eye) is specified in the documentation, use the more specific codes (H04.031 or H04.032).
• Ensure the documentation differentiates between lacrimal gland enlargement and lacrimal sac disorders, which are coded differently.
