ICD-10 Code H04.332 – Acute lacrimal canaliculitis of left lacrimal passage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.332 – Acute lacrimal canaliculitis of left lacrimal passage
What it is
This code identifies an acute infection and inflammation of the left lacrimal canaliculus, the small tear-drainage channel near the inner eyelid. Use it when documentation specifies the left side and an acute canaliculitis.
Clinical signs
Typical findings include localized tenderness, swelling, redness, and discharge near the punctum on the left side. Clinical features vary; refer to documentation for confirmatory exam findings such as canalicular inflammation or expressed material.
When to use this code
Use H04.332 when the provider documents acute canaliculitis affecting the left lacrimal passage. It is appropriate for encounters where the diagnosis is established from exam findings or specialist assessment. Code the laterality exactly as documented.
Do not use for
Do not use this code for unspecified, chronic, or right-sided canaliculitis. Check documentation if the record mentions broader tear-duct infection, since that may require a different code.
Coding tip
Verify both acuity and laterality in the note before assigning H04.332.
