ICD-10 Code H04.56 – Stenosis of lacrimal punctum (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.56 – Stenosis of lacrimal punctum
What it is
H04.56 identifies narrowing of the lacrimal punctum, the small opening that drains tears from the eye into the tear duct. This blockage can impair tear drainage and contribute to tearing.
Clinical signs
Typical findings include persistent tearing, tear overflow onto the cheek, and a punctum that appears narrowed or difficult to probe. Clinical features vary; refer to documentation.
When to use this code
Use H04.56 when the record documents punctal stenosis as the diagnosed reason for impaired tear drainage. It is appropriate when the provider specifically identifies narrowing of the punctum, with or without epiphora. Check documentation if the note only describes tearing without a confirmed cause.
Do not use for
Do not use this code for general dry eye, conjunctivitis, or nasolacrimal duct obstruction unless punctal stenosis is clearly documented. Avoid it when the chart does not specify the punctum as the site of narrowing.
Coding tip
Assign H04.56 only when the provider links symptoms to punctal stenosis, not when tearing is recorded alone.
