ICD-10 Code H15.119 – Episcleritis periodica fugax, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.119 – Episcleritis periodica fugax, unspecified eye
What it is
This code identifies episodic episcleritis affecting an unspecified eye. It refers to inflammation of the episclera, the thin tissue over the white of the eye, with no eye laterality documented.
Clinical signs
Typical findings include localized redness, mild pain or tenderness, and tearing. Clinical features vary; refer to documentation, especially when the record does not specify the affected eye.
When to use this code
Use H15.119 when the provider documents episcleritis periodica fugax and does not state right or left eye. Apply it for confirmed episcleritis episodes, not for nonspecific eye redness without a diagnosis. Check documentation if the note is incomplete.
Do not use for
Do not use this code for scleritis, conjunctivitis, or other causes of red eye. If the record identifies a specific eye, choose the laterality-specific code instead.
Coding tip
Always verify laterality in the assessment or diagnosis section before assigning H15.119.
