ICD-10 Code H04.133 – Lacrimal cyst, bilateral lacrimal glands (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.133 – Lacrimal cyst, bilateral lacrimal glands
What it is
This code identifies a cystic lesion involving both lacrimal glands, the tear-producing glands above each eye. Use it when the documentation specifically states bilateral lacrimal gland cysts.
Clinical signs
Clinical features vary; refer to documentation. Findings may include a painless or mildly tender swelling in the upper outer eyelid area, with imaging or exam noting cysts in both lacrimal glands.
When to use this code
Use H04.133 when the provider documents lacrimal cysts in both glands, whether found on examination, imaging, or specialist evaluation. Code it when the diagnosis is confirmed and laterality is bilateral. If the chart only says “lacrimal cyst” without side, check documentation.
Do not use for
Do not use this code for a cyst in only one lacrimal gland or for nonspecific eyelid swelling without a documented lacrimal gland cyst. Check documentation if the lesion is described as inflammatory or otherwise different.
Coding tip
Always verify laterality in the ophthalmology note or imaging report before assigning H04.133.
