ICD-10 Code H04.419 – Chronic dacryocystitis of unspecified lacrimal passage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.419 – Chronic dacryocystitis of unspecified lacrimal passage
What it is
This code identifies chronic inflammation or infection of the lacrimal sac when the exact lacrimal passage is not specified. It is used when documentation confirms dacryocystitis but does not name a more precise site.
Clinical signs
Typical findings include persistent tearing, discharge, and tenderness or swelling near the inner corner of the eye. Clinical features vary; refer to documentation for chronicity and the involved lacrimal passage.
When to use this code
Use H04.419 when the record states chronic dacryocystitis and the provider does not identify a specific lacrimal passage. It also fits follow-up or consultation notes that continue to document the condition without further anatomic detail.
If the note mentions acute infection, obstruction alone, or a different lacrimal disorder, this code is not the best choice. You should code only what is clearly documented.
Do not use for
Do not use this code for acute dacryocystitis or for simple tearing without inflammation. Check documentation if the chart describes another lacrimal sac disorder or a more specific lacrimal passage.
Coding tip
Query for laterality or a more specific lacrimal site when the diagnosis is vague, because H04.419 is for unspecified lacrimal passage only.
