ICD-10 Code H04.329 – Acute dacryocystitis of unspecified lacrimal passage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.329 – Acute dacryocystitis of unspecified lacrimal passage
What it is
This code identifies an acute infection and inflammation of the lacrimal sac when the exact lacrimal passage is not specified in the record. Use it when documentation confirms acute dacryocystitis but does not name a more precise side or site.
Clinical signs
Typical findings include painful swelling near the inner corner of the eye, redness, tearing, and possible discharge. Clinical features vary; refer to documentation for the exact presentation and laterality.
When to use this code
Use this code when the clinician documents acute dacryocystitis and does not identify a more specific lacrimal passage. It also fits when the record states the condition is unspecified or the site cannot be determined from available documentation. Check documentation if laterality or a different lacrimal disorder is mentioned.
Do not use for
Do not use this code for chronic dacryocystitis, congenital lacrimal disorders, or general eye redness without documented lacrimal sac infection. If the note specifies a different lacrimal passage, choose the more exact code.
Coding tip
Always look for laterality and whether the provider named the lacrimal sac versus another lacrimal structure.
