ICD-10 Code H04.422 – Chronic lacrimal canaliculitis of left lacrimal passage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.422 – Chronic lacrimal canaliculitis of left lacrimal passage
What it is
This code identifies chronic inflammation or infection of the left lacrimal canaliculus, the small tear-drainage channel near the inner eyelid. It indicates a persistent problem limited to the left lacrimal passage.
Clinical signs
Typical findings include chronic tearing, eyelid tenderness, discharge, or swelling near the punctum. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents chronic canaliculitis affecting the left lacrimal passage. It is appropriate for ongoing or recurrent canalicular infection/inflammation that is clearly localized to the left side. Do not infer laterality from symptoms alone.
Do not use for
Do not use it for acute canaliculitis without chronicity or for unspecified lacrimal disorders. If the record does not clearly identify the left side or the condition, check documentation.
Coding tip
Confirm both chronicity and left-sided laterality in the note before assigning H04.422.
