ICD-10 Code H04.319 – Phlegmonous dacryocystitis of unspecified lacrimal passage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.319 – Phlegmonous dacryocystitis of unspecified lacrimal passage
What it is
Use this code for an acute, suppurative infection of the lacrimal sac when the affected lacrimal passage is not specified. It indicates phlegmonous dacryocystitis, meaning spreading inflammation with pus formation.
Clinical signs
Typical findings include painful swelling and redness near the inner corner of the eye, tearing, and tenderness over the lacrimal sac. Clinical features vary; refer to documentation.
When to use this code
Assign H04.319 when the record documents phlegmonous dacryocystitis and does not identify a specific lacrimal passage. Use it for provider notes describing an acute infected lacrimal sac without further laterality or site detail. Check documentation if the chart mentions a different lacrimal disorder.
Do not use for
Do not use this code for chronic dacryocystitis, congenital obstruction, or noninfectious tearing disorders. If the note identifies a different lacrimal passage or a more specific site, code that instead.
Coding tip
Look for laterality and exact lacrimal site in the note before defaulting to the unspecified code.
