ICD-10 Code H04.323 – Acute dacryocystitis of bilateral lacrimal passages (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.323 – Acute dacryocystitis of bilateral lacrimal passages
What it is
H04.323 identifies acute inflammation and infection of both lacrimal sacs, the tear drainage reservoirs near the inner corners of the eyes. Use it when documentation clearly states acute dacryocystitis affecting both sides.
Clinical signs
Typical findings include pain, swelling, redness, and tenderness at the medial canthus, with possible tearing or discharge. Clinical features vary; refer to documentation for bilateral involvement and acute presentation.
When to use this code
Use this code when the provider documents acute dacryocystitis in both lacrimal passages, lacrimal sacs, or tear sacs. It is appropriate when the condition is active and not described as chronic, unspecified, or limited to one side. If laterality is unclear, check documentation.
Do not use for
Do not use H04.323 for chronic dacryocystitis, congenital lacrimal disorders, or nonspecific eye redness without a documented lacrimal sac infection. Check documentation if the note does not confirm acute bilateral disease.
Coding tip
Match the code to both acuity and laterality; “acute” and “bilateral” must both be documented.
