ICD-10 Code H04.13 – Lacrimal cyst (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.13 – Lacrimal cyst
What it is
H04.13 identifies a cyst of the lacrimal apparatus. Use it when documentation describes a lacrimal cyst, usually a localized, fluid-filled swelling near the tear drainage system.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see a painless or mildly tender mass near the inner eye or eyelid, with possible tearing if the lacrimal drainage pathway is affected.
When to use this code
Use this code when the provider documents a lacrimal cyst, including a cyst of the lacrimal sac or adjacent lacrimal structures. Code only when the record clearly identifies the lesion as cystic and located in the lacrimal system. Check documentation if the note instead describes swelling, obstruction, or another eye disorder.
Do not use for
Do not use this code for nonspecific eye swelling, infection, or tear duct obstruction without a documented cyst. If the diagnosis is different or unclear, check documentation.
Coding tip
Match the code to the exact anatomic site and avoid assuming a cyst when the chart only says “mass” or “lesion.”
