ICD-10 Code H15.0 – Scleritis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.0 – Scleritis
What it is
H15.0 identifies scleritis, an inflammatory disorder of the sclera, the white outer coat of the eye. Use it when documentation clearly states scleritis or scleral inflammation.
Clinical signs
Typical findings include deep eye pain, redness, and tenderness, often with pain on eye movement. Clinical features vary; refer to documentation.
When to use this code
Use H15.0 when the provider documents scleritis, including anterior or posterior forms, and no more specific code is given. It may appear with eye pain, redness, or specialist evaluation confirming scleral inflammation. Check documentation if the note only says “red eye” or “eye irritation.”
Do not use for
Do not use this code for conjunctivitis, episcleritis, or nonspecific ocular redness without documented scleral inflammation. If the diagnosis is uncertain, check documentation.
Coding tip
Code the documented diagnosis, not just symptoms, and confirm whether the record specifies scleritis versus episcleritis or another eye disorder.
