ICD-10 Code H04.541 – Stenosis of right lacrimal canaliculi (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.541 – Stenosis of right lacrimal canaliculi
What it is
H04.541 identifies narrowing of the right lacrimal canaliculus, one of the small drainage channels that carry tears from the eye toward the nose. Use it when documentation specifies right-sided canalicular stenosis.
Clinical signs
Typical findings include tearing, tear drainage delay, and possible overflow of tears onto the cheek. Clinical features vary; refer to documentation, especially when the note confirms canalicular narrowing on the right.
When to use this code
Use this code when the provider documents stenosis, stricture, or narrowing of the right lacrimal canaliculus. It may also apply when the chart links right-sided tear drainage obstruction to canalicular narrowing rather than another lacrimal structure. Check documentation if laterality is unclear.
Do not use for
Do not use H04.541 for left-sided, bilateral, or unspecified lacrimal drainage stenosis. Do not assign it for general epiphora or other lacrimal disorders unless the record clearly states right canalicular stenosis.
Coding tip
Confirm both the anatomic site and laterality in the ophthalmology note before coding.
