ICD-10 Code H04.222 – Epiphora due to insufficient drainage, left side (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.222 – Epiphora due to insufficient drainage, left side
What it is
This code identifies tearing of the left eye caused by poor tear drainage. It applies when the nasolacrimal outflow system is insufficient rather than when excess tear production is the main issue.
Clinical signs
Typical findings include persistent or recurrent tearing from the left eye, overflow of tears onto the cheek, and possible irritation from constant moisture. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents epiphora due to insufficient drainage affecting the left side. It is appropriate for confirmed tear outflow obstruction or reduced drainage documented as the cause of tearing. Check documentation if the record only states watery eyes without a cause.
Do not use for
Do not use this code when tearing is due to increased tear production, bilateral involvement, or an unspecified side. If the chart does not clearly identify insufficient drainage, check documentation.
Coding tip
Verify laterality and the documented cause of tearing before assigning H04.222.
