ICD-10 Code H04.03 – Chronic enlargement of lacrimal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.03 – Chronic enlargement of lacrimal gland
What it is
H04.03 identifies a chronic, nonacute enlargement of the lacrimal gland, the tear-producing gland located above the outer eye. Use it when the chart documents persistent gland enlargement rather than a short-term inflammatory process.
Clinical signs
Typical findings include a visible or palpable fullness in the upper outer orbit, sometimes with eyelid swelling or eye displacement. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents chronic enlargement of the lacrimal gland as the diagnosis. It may apply when imaging or examination confirms persistent gland enlargement without a more specific underlying condition recorded. If the note names a different disorder, code that condition instead.
Do not use for
Do not use H04.03 for acute lacrimal gland inflammation, swelling from infection, or other specified orbital disease. Check documentation if the enlargement is part of a broader systemic or neoplastic diagnosis.
Coding tip
Code the documented chronic enlargement only when it is stated clearly; otherwise, query for the exact lacrimal gland diagnosis.
