ICD-10 Code H04.033 – Chronic enlargement of bilateral lacrimal glands (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.033 – Chronic enlargement of bilateral lacrimal glands
What it is
This code identifies a persistent, bilateral enlargement of the lacrimal glands, which produce tears. It describes the finding itself, not a specific underlying disease.
Clinical signs
You may see fullness or swelling in both upper outer eyelids, sometimes with visible gland prominence on exam. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly documents chronic enlargement of both lacrimal glands. It is appropriate for outpatient or specialist notes that describe bilateral gland enlargement without a more specific diagnosis. If the cause is identified, code the confirmed condition instead.
Do not use for
Do not use it for acute swelling, unilateral enlargement, or nonspecific eyelid edema. Check documentation if the note describes a mass, infection, or another underlying disorder.
Coding tip
Confirm that “chronic” and “bilateral” are both documented before assigning H04.033.
