ICD-10 Code H04.009 – Unspecified dacryoadenitis, unspecified lacrimal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.009 – Unspecified dacryoadenitis, unspecified lacrimal gland
What it is
This code identifies inflammation of a lacrimal gland when the gland is not further specified. Use it when the record documents dacryoadenitis but does not name a side or a more precise cause.
Clinical signs
Typical findings include eyelid swelling, pain or tenderness near the outer upper eyelid, and possible tearing or redness. Clinical features vary; refer to documentation.
When to use this code
Use H04.009 when the provider documents dacryoadenitis and the chart does not identify the right or left lacrimal gland. It also fits when the inflammation is recorded as unspecified and no more detailed code is supported. Check documentation if the note suggests an infectious, autoimmune, or other named cause.
Do not use for
Do not use this code for a specified lacrimal gland, such as right or left, when laterality is documented. Also avoid it if the record supports a different lacrimal disorder or a clearer underlying diagnosis.
Coding tip
Query for laterality and cause before assigning H04.009, because a more specific code may be available.
