2026 ICD-10-CM Diagnosis Code H04.331 – Acute lacrimal canaliculitis of right lacrimal passage
What it is
This code identifies an acute infection and inflammation of the lacrimal canaliculus on the right side. It applies when documentation specifies the right lacrimal passage and the condition is acute.
Clinical signs
Typical findings include localized tenderness, swelling, redness, and discharge near the punctum or canaliculus. Clinical features vary; refer to documentation for laterality and acute presentation.
When to use this code
Use this code when the provider documents acute canaliculitis affecting the right lacrimal passage. It is appropriate for confirmed right-sided disease, including notes describing canalicular infection, inflammation, or purulent drainage. Check documentation if laterality or acuity is unclear.
Do not use for
Do not use this code for chronic canaliculitis, unspecified lacrimal disorders, or conditions limited to the lacrimal sac. If the record does not clearly state the right side, check documentation.
Coding tip
Verify both acuity and laterality in the provider note before assigning H04.331.
