ICD-10 Code H15.11 – Episcleritis periodica fugax (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.11 – Episcleritis periodica fugax
What it is
H15.11 identifies episodic episcleritis, an inflammation of the episclera, the thin tissue over the white part of the eye. Use it when the record specifically documents episodic or recurrent episcleritis.
Clinical signs
Typical findings include localized redness, mild eye discomfort, and tenderness without major vision loss. Clinical features vary; refer to documentation.
When to use this code
Use H15.11 when the clinician documents episcleritis periodica fugax or clearly states recurrent episcleritis. It may also fit when the note describes repeated self-limited episodes affecting one or both eyes. Check documentation if the record only says “red eye” or “eye irritation.”
Do not use for
Do not use this code for scleritis, conjunctivitis, or nonspecific ocular redness. If the diagnosis is uncertain or another inflammatory eye disorder is documented, code the stated condition instead.
Coding tip
Code only when the provider documents episcleritis and its episodic nature; otherwise, query or use the most specific documented eye diagnosis.
