ICD-10 Code H04.619 – Lacrimal fistula unspecified lacrimal passage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.619 – Lacrimal fistula unspecified lacrimal passage
What it is
This code identifies an abnormal fistulous opening involving the lacrimal drainage system, with no site of the passage further specified. It indicates a tear-duct connection to the skin or another surface.
Clinical signs
Typical findings include persistent tearing, intermittent drainage, or a small opening near the medial canthus. Clinical features vary; refer to documentation if the exact lacrimal passage involved is not stated.
When to use this code
Use H04.619 when the record documents a lacrimal fistula but does not name the specific lacrimal passage. It also fits cases where the provider describes an unspecified tear-duct fistula without laterality or more precise anatomy. If the note identifies a different lacrimal disorder, choose the more specific code.
Do not use for
Do not use this code for simple tearing, blocked tear ducts, or infections without a fistula. Check documentation if the finding is a canalicular, lacrimal sac, or other specified lesion.
Coding tip
Code to the highest documented specificity, and query the provider if the fistula site is described but not clearly named.
