ICD-10 Code H15.112 – Episcleritis periodica fugax, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.112 – Episcleritis periodica fugax, left eye
What it is
H15.112 identifies episodic episcleritis affecting the left eye. It refers to a localized, usually self-limited inflammation of the episclera, the thin tissue between the conjunctiva and sclera.
Clinical signs
Typical findings include sectoral redness, mild discomfort, and ocular tenderness in the left eye. Clinical features vary; refer to documentation, especially when the record specifically names episcleritis periodica fugax.
When to use this code
Use this code when the provider documents episodic episcleritis in the left eye, including recurrent or transient flares. Apply it when the diagnosis is confirmed in the chart and laterality is clearly stated. Check documentation if the note only says “eye redness” or “episcleritis” without left-eye specificity.
Do not use for
Do not use H15.112 for conjunctivitis, scleritis, or nonspecific ocular irritation. If the record does not confirm episcleritis periodica fugax or left-eye involvement, check documentation.
Coding tip
Match the code to both the condition name and laterality; if either is missing, query the provider before assigning H15.112.
