ICD-10 Code H04.429 – Chronic lacrimal canaliculitis of unspecified lacrimal passage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.429 – Chronic lacrimal canaliculitis of unspecified lacrimal passage
What it is
This code identifies chronic inflammation or infection of the lacrimal canaliculus when the affected lacrimal passage is not specified. It is used for a long-standing tear drainage problem involving the canalicular segment.
Clinical signs
Typical findings may include persistent tearing, localized tenderness, swelling near the inner eyelid, or discharge from the punctum. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents chronic canaliculitis and does not identify a specific lacrimal passage site. It also fits cases where the record confirms canalicular inflammation but laterality or exact passage details are missing. Check documentation if the note is unclear.
Do not use for
Do not use this code for acute canaliculitis, dacryocystitis, or nonspecific conjunctivitis. If the documentation names a different lacrimal structure, code that condition instead.
Coding tip
Confirm that the record says “chronic” and “unspecified lacrimal passage” before assigning H04.429.
