ICD-10 Code H15.01 – Anterior scleritis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.01 – Anterior scleritis
What it is
H15.01 identifies inflammation of the anterior portion of the sclera, the white outer coat of the eye. It is used when documentation specifically states anterior scleritis.
Clinical signs
Typical findings include a painful, red eye with scleral tenderness and visible deep episcleral or scleral injection. Clinical features vary; refer to documentation.
When to use this code
Use H15.01 when the record clearly documents anterior scleritis as the diagnosis. Apply it for ophthalmology visits, consults, or problem lists where the provider identifies inflammation of the anterior sclera.
If the note only says “scleritis” without location, check documentation before assigning this code. Code the most specific diagnosis available in the chart.
Do not use for
Do not use this code for conjunctivitis, episcleritis, or nonspecific eye redness. It also should not be used when the diagnosis is uncertain or not documented.
Coding tip
Look for the word “anterior” in the provider’s assessment; if it is missing, verify the site before coding.
