ICD-10 Code H04.011 – Acute dacryoadenitis, right lacrimal gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.011 – Acute dacryoadenitis, right lacrimal gland
What it is
Use this code for acute inflammation of the right lacrimal gland, the tear-producing gland located above the outer part of the eye. It indicates a sudden, localized inflammatory process on the right side.
Clinical signs
Typical findings include pain or tenderness in the upper outer eyelid, swelling of the right upper lid, and possible redness or fullness in the lacrimal gland area. Clinical features vary; refer to documentation.
When to use this code
Assign H04.011 when the provider documents acute dacryoadenitis involving the right lacrimal gland. Use it for confirmed right-sided disease, even if the note also describes eyelid swelling or eye discomfort. Check documentation if the laterality or acuity is unclear.
Do not use for
Do not use this code for left-sided, bilateral, or unspecified dacryoadenitis. Also avoid it when the record describes a different lacrimal disorder or general eye swelling without acute right lacrimal gland inflammation.
Coding tip
Verify both acuity and laterality in the provider note before assigning H04.011.
