ICD-10 Code H04.131 – Lacrimal cyst, right lacrimal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.131 – Lacrimal cyst, right lacrimal gland
What it is
This code identifies a cystic lesion of the right lacrimal gland. It indicates a localized fluid-filled sac in the tear-producing gland on the right side.
Clinical signs
Typical findings include a palpable or visible mass in the right upper outer eyelid area. Clinical features vary; refer to documentation for laterality, size, and whether the lesion is symptomatic or incidental.
When to use this code
Use H04.131 when the provider documents a lacrimal cyst specifically involving the right lacrimal gland. You should code it when the record clearly identifies the lesion as cystic and right-sided. If the note only says “lacrimal mass” or is unclear, check documentation before assigning this code.
Do not use for
Do not use this code for lacrimal gland inflammation, obstruction, or other non-cystic disorders. Do not assign it when the side is not documented or when the finding is unrelated to the lacrimal gland.
Coding tip
Verify both the gland location and laterality in the provider note before coding.
