ICD-10 Code H15.099 – Other scleritis, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.099 – Other scleritis, unspecified eye
What it is
This code identifies scleritis affecting an unspecified eye when the documented type is other than the standard categories. Use it for inflammation of the sclera when the record does not name the right or left eye.
Clinical signs
Typical findings include deep eye pain, redness, and tenderness, often with pain on eye movement. Clinical features vary; refer to documentation for the specific scleritis type and laterality.
When to use this code
Use H15.099 when the provider documents other scleritis and does not specify the eye involved. It also fits cases where the note confirms scleritis but the subtype is atypical or not otherwise classified. Check documentation if laterality is available elsewhere in the record.
Do not use for
Do not use this code for episcleritis, keratitis, or nonspecific eye redness without a scleritis diagnosis. If the chart identifies a specific eye, code the laterality-supported option instead.
Coding tip
Confirm both the scleritis type and eye laterality in the provider note before assigning H15.099.
