ICD-10-CM H04.039: Chronic enlargement of unspecified lacrimal gland

ICD-10-CM code H04.039 designates a diagnosis of chronic enlargement of an unspecified lacrimal gland, classified as a disease or syndrome. The terminology is active for the 2026 version and is used when laterality is not specified. Clinical literature describes chronic lacrimal gland inflammation as potentially involving progressive, painless enlargement. 1 2

Clinical context

Chronic dacryoadenitis may present as a progressively enlarging, painless gland, and clinical evaluation of lacrimal gland enlargement involves palpating the gland for tenderness and consistency. 2

Chronic noninfectious dacryoadenitis involves lymphocyte and plasma cell infiltration leading to progressive fibrosis, and autoimmune forms may lead to persistent inflammation and lacrimal gland dysfunction. 2

Documentation considerations

Clinical assessment of lacrimal gland enlargement includes evaluating eyelid edema, conjunctival injection, and chemosis, and checking for symptoms of an underlying systemic disorder. 2
