ICD-10 Code H04.013 – Acute dacryoadenitis, bilateral lacrimal glands (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.013 – Acute dacryoadenitis, bilateral lacrimal glands
What it is
H04.013 identifies acute inflammation of both lacrimal glands, the tear-producing glands located in the upper outer eyelids. Use it when documentation clearly states bilateral acute dacryoadenitis.
Clinical signs
Typical findings include painful swelling or tenderness in the outer upper eyelid area, often with redness and a “S-shaped” lid contour. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents acute dacryoadenitis affecting both lacrimal glands, or clearly describes bilateral lacrimal gland inflammation. It may appear in ophthalmology or emergency records with localized eyelid swelling and pain. Check documentation if laterality is unclear.
Do not use for
Do not use H04.013 for unspecified, chronic, or unilateral dacryoadenitis. If the note does not confirm both glands are involved, choose the more accurate documented laterality or unspecified code.
Coding tip
Verify laterality in the assessment, not just the exam findings, before assigning H04.013.
