ICD-10 Code H15.03 – Posterior scleritis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.03 – Posterior scleritis
What it is
Posterior scleritis is inflammation of the back part of the sclera, the white outer coat of the eye. It can cause pain and visual disturbance, and you code it when documentation identifies this specific posterior form.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include eye pain, reduced vision, and signs of posterior ocular inflammation on exam or imaging.
When to use this code
Use H15.03 when the provider documents posterior scleritis or posterior inflammation of the sclera. It is appropriate when the diagnosis is confirmed clinically or by ophthalmic evaluation. If the note only says “scleritis” without location, check documentation before assigning this code.
Do not use for
Do not use this code for anterior scleritis, episcleritis, or nonspecific eye pain without a documented diagnosis. If the record does not specify posterior involvement, check documentation.
Coding tip
Code the most specific scleritis type documented, and query the provider if the laterality or location is unclear.
