ICD-10 Code H04.00 – Unspecified dacryoadenitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.00 – Unspecified dacryoadenitis
What it is
H04.00 identifies inflammation of the lacrimal gland when the record does not specify acute, chronic, or another defined form. Use it for nonspecific dacryoadenitis documented by the clinician.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include swelling or tenderness near the outer upper eyelid, possible redness, and discomfort around the eye.
When to use this code
Use this code when the provider documents dacryoadenitis but does not identify a specific cause or type. It also fits cases where the chart only says “lacrimal gland inflammation” or “unspecified dacryoadenitis.”
If the note names a more specific diagnosis, code that instead. Check documentation when laterality, etiology, or acuity is stated elsewhere in the record.
Do not use for
Do not use H04.00 for dry eye, tear duct obstruction, or other lacrimal disorders without gland inflammation. If the condition is specified as acute, chronic, or due to a known cause, choose the more specific code.
Coding tip
Query the provider if the note only says “eye swelling” and dacryoadenitis is not explicitly documented.
