ICD-10 Code H04.57 – Stenosis of lacrimal sac (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.57 – Stenosis of lacrimal sac
What it is
H04.57 identifies narrowing of the lacrimal sac, which can obstruct normal tear drainage. Use it when documentation states stenosis of the lacrimal sac or an equivalent diagnosis.
Clinical signs
Typical findings include tearing, recurrent discharge, and symptoms of impaired nasolacrimal drainage. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents stenosis of the lacrimal sac as the diagnosed condition. It may also fit when evaluation confirms a narrowed lacrimal sac causing chronic tearing or drainage problems. Check documentation if the note instead describes obstruction at a different tear-duct level.
Do not use for
Do not assign H04.57 for simple eye watering without a documented lacrimal sac stenosis. Do not use it when the record identifies another cause or site of obstruction; check documentation.
Coding tip
Code only when the lacrimal sac narrowing is explicitly documented, and verify whether the issue is congenital, acquired, or part of a broader obstruction diagnosis.
