ICD-10 Code H04.039 – Chronic enlargement of unspecified lacrimal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.039 – Chronic enlargement of unspecified lacrimal gland
What it is
This code identifies a chronic, ongoing enlargement of the lacrimal gland when the affected side is not specified. It describes a persistent abnormal increase in gland size, not a temporary tear production issue.
Clinical signs
Clinical features may include a palpable or visible swelling in the upper outer eyelid area, sometimes with discomfort or fullness. Clinical features vary; refer to documentation.
When to use this code
Use H04.039 when the provider documents chronic enlargement of the lacrimal gland and does not identify right or left laterality. Apply it for confirmed cases in outpatient, inpatient, or specialist notes when the diagnosis is the focus of care.
If the record only mentions lacrimal gland swelling without chronicity, or if another cause is documented, check documentation before assigning this code.
Do not use for
Do not use this code for acute lacrimal gland enlargement, unspecified eyelid swelling, or general tearing complaints. If the note names a different lacrimal disorder, code that condition instead.
Coding tip
Always verify that the documentation states “chronic” and does not specify a side before selecting H04.039.
