ICD-10 Code H15.033 – Posterior scleritis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.033 – Posterior scleritis, bilateral
What it is
Posterior scleritis is inflammation of the back part of the sclera, the white outer coat of the eye. Bilateral means both eyes are involved.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include eye pain, blurred vision, and signs of posterior eye inflammation on exam or imaging.
When to use this code
Use H15.033 when the provider documents posterior scleritis affecting both eyes. Code it from a confirmed diagnosis, not from nonspecific eye pain or suspected inflammation alone. If the record does not clearly state bilaterality, check documentation before assigning this code.
Do not use for
Do not use this code for anterior scleritis, isolated ocular pain, or an unspecified scleritis diagnosis. If the laterality is not documented as bilateral, choose the more accurate code or check documentation.
Coding tip
Confirm both the posterior location and bilateral laterality in the provider note before coding H15.033.
