ICD-10 Code H04.551 – Acquired stenosis of right nasolacrimal duct (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.551 – Acquired stenosis of right nasolacrimal duct
What it is
Use this code for a narrowed right nasolacrimal duct caused by an acquired condition, not a congenital defect. It describes impaired tear drainage on the right side.
Clinical signs
Common findings include tearing from the right eye, recurrent discharge, or symptoms of tear drainage obstruction. Clinical features vary; refer to documentation.
When to use this code
Assign H04.551 when the record clearly documents acquired stenosis of the right nasolacrimal duct. Use it for confirmed right-sided obstruction or narrowing affecting tear outflow.
Choose this code when the provider specifies the right side and the condition is acquired rather than congenital. Check documentation if the note only says epiphora or lacrimal drainage problem.
Do not use for
Do not use this code for congenital nasolacrimal duct stenosis or unspecified laterality. Also avoid it when the chart does not confirm an acquired right-sided stenosis.
Coding tip
Verify laterality and whether the stenosis is acquired before coding, because unspecified or congenital cases need different ICD-10-CM choices.
