ICD-10 Code H04.019 – Acute dacryoadenitis, unspecified lacrimal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.019 – Acute dacryoadenitis, unspecified lacrimal gland
What it is
H04.019 identifies acute inflammation of a lacrimal gland when the affected gland is not specified. Use it for a sudden, nonspecific dacryoadenitis diagnosis documented by the clinician.
Clinical signs
Typical findings include painful swelling of the outer upper eyelid, redness, and tenderness near the lacrimal gland. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states acute dacryoadenitis but does not identify right, left, or bilateral involvement. It also fits cases where the provider documents lacrimal gland inflammation without further detail. Check documentation if laterality is specified elsewhere.
Do not use for
Do not use it for chronic dacryoadenitis or other lacrimal system disorders. If the note specifies a different gland, laterality, or a noninflammatory eye condition, choose the documented diagnosis instead.
Coding tip
Review the ophthalmology note for laterality and acuity before assigning H04.019.
