ICD-10 Code H15.10 – Unspecified episcleritis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.10 – Unspecified episcleritis
What it is
H15.10 identifies episcleritis when the chart does not specify a type or cause. It refers to inflammation of the episclera, the thin tissue covering the white of the eye.
Clinical signs
Typical findings include localized eye redness, mild discomfort, and tenderness over the affected area. Vision is usually preserved; clinical features vary, so refer to documentation.
When to use this code
Use this code when the provider documents episcleritis but does not name it as simple, nodular, or another subtype. It also fits when the record confirms episcleral inflammation without further detail. If the note describes a different ocular surface disorder, check documentation before coding.
Do not use for
Do not use H15.10 for scleritis, conjunctivitis, or nonspecific eye redness without a documented diagnosis. If the condition is specified more clearly, code the documented subtype instead.
Coding tip
Code only when episcleritis is explicitly documented; otherwise, query for clarification.
