ICD-10 Code H04.32 – Acute dacryocystitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.32 – Acute dacryocystitis
What it is
Acute dacryocystitis is a sudden infection and inflammation of the lacrimal sac, usually related to blockage of the tear drainage system. It commonly causes painful swelling near the inner corner of the eye.
Clinical signs
Typical findings include tenderness, redness, and swelling over the lacrimal sac, with tearing or discharge from the punctum. Clinical features vary; refer to documentation if the presentation is atypical.
When to use this code
Use H04.32 when the record clearly documents acute dacryocystitis, including suspected or confirmed infection of the lacrimal sac. Code it for acute episodes with localized pain, swelling, or drainage at the inner canthus. If the note only mentions tearing or obstruction without infection, check documentation.
Do not use for
Do not use this code for chronic dacryocystitis, congenital nasolacrimal duct obstruction, or nonspecific eye redness without lacrimal sac infection. Check documentation when the diagnosis is unclear.
Coding tip
Code the condition only when the provider identifies it as acute dacryocystitis, not just blocked tear duct symptoms.
