ICD-10 Code H04.031 – Chronic enlargement of right lacrimal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.031 – Chronic enlargement of right lacrimal gland
What it is
This code identifies a long-standing enlargement of the right lacrimal gland, the tear-producing gland in the upper outer part of the orbit. It describes a localized finding, not a specific underlying cause.
Clinical signs
Typical findings include persistent fullness or swelling in the right upper eyelid or outer orbit, sometimes with globe displacement or discomfort. Clinical features vary; refer to documentation.
When to use this code
Use H04.031 when the provider documents chronic enlargement of the right lacrimal gland and the condition is not better explained by a more specific diagnosis. It may be used when imaging or examination notes a persistent unilateral gland enlargement. Confirm laterality and chronicity in the record.
Do not use for
Do not use this code for acute swelling, bilateral enlargement, or lacrimal gland disease with a clearly documented underlying cause that has a more specific code. Check documentation.
Coding tip
Always verify right-sided laterality and chronicity before assigning H04.031.
