ICD-10 Code H15.101 – Unspecified episcleritis, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.101 – Unspecified episcleritis, right eye
What it is
H15.101 identifies episcleritis affecting the right eye when the type is not further specified. It refers to inflammation of the episcleral tissue, the thin layer between the conjunctiva and sclera.
Clinical signs
Typical findings include localized redness, mild discomfort, and eye irritation; vision is usually preserved. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents episcleritis in the right eye but does not specify a subtype. It also fits cases labeled as unspecified episcleritis after exam. Code only when the record clearly supports right-eye involvement.
Do not use for
Do not use it for scleritis, conjunctivitis, or other causes of red eye. If the laterality is not right eye, or the diagnosis is more specific, code that documented condition instead.
Coding tip
Check the note for laterality and specificity; unspecified codes are appropriate only when the provider leaves the condition uncharacterized.
