ICD-10 Code H04.411 – Chronic dacryocystitis of right lacrimal passage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.411 – Chronic dacryocystitis of right lacrimal passage
What it is
H04.411 identifies chronic inflammation or infection of the tear sac on the right side. Use it when documentation specifies the right lacrimal passage and a chronic dacryocystitis diagnosis.
Clinical signs
Typical findings include persistent tearing, discharge, and tenderness or swelling near the inner corner of the right eye. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents chronic dacryocystitis affecting the right lacrimal passage, tear sac, or nasolacrimal drainage system. It is appropriate for ongoing or recurrent disease, not a one-time acute episode. If laterality is not stated, check documentation before coding.
Do not use for
Do not use H04.411 for acute dacryocystitis or for disease on the left side or both sides. Do not apply it when the note only says eye tearing without a confirmed lacrimal sac infection.
Coding tip
Confirm both chronicity and right-sided laterality in the provider note before assigning H04.411.
