ICD-10 Code H15.103 – Unspecified episcleritis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.103 – Unspecified episcleritis, bilateral
What it is
H15.103 identifies episcleritis affecting both eyes when the chart does not specify a cause or subtype. It refers to inflammation of the episclera, the thin tissue over the white of the eye.
Clinical signs
Typical findings include sectoral or diffuse redness, mild eye discomfort, and tenderness. Vision is usually preserved; if pain is severe or vision changes are present, check documentation for another diagnosis.
When to use this code
Use this code when the provider documents bilateral episcleritis and does not identify it as simple, nodular, or another specific form. It also fits when the note states episcleritis but gives no additional detail. If laterality is not confirmed, check documentation before coding.
Do not use for
Do not use this code for scleritis, conjunctivitis, or other causes of red eye. If the record supports a more specific episcleritis type or a different laterality, code that instead.
Coding tip
Confirm both laterality and specificity in the ophthalmology note before assigning H15.103.
