ICD-10 Code H15.003 – Unspecified scleritis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.003 – Unspecified scleritis, bilateral
What it is
H15.003 identifies scleritis affecting both eyes when the type is not further specified. It indicates inflammation of the sclera, the white outer layer of the eye.
Clinical signs
Typical findings include deep eye pain, redness, and tenderness, often with bilateral involvement. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents scleritis in both eyes but does not name the subtype, such as anterior, posterior, or necrotizing. It also fits cases where the chart confirms bilateral scleritis and no more specific diagnosis is recorded.
Do not use for
Do not use it when the record specifies a different type of scleritis or involvement of only one eye. Check documentation if the note describes another inflammatory eye disorder instead.
Coding tip
Code the most specific scleral diagnosis documented; if laterality or subtype is missing, use H15.003 only when bilateral involvement is clear.
