ICD-10 Code H15.00 – Unspecified scleritis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.00 – Unspecified scleritis
What it is
H15.00 identifies scleritis when the chart does not specify the type or location. It is an inflammatory disorder of the sclera, the white outer coat of the eye.
Clinical signs
Typical findings include deep eye pain, redness, and tenderness, often with photophobia or reduced vision. Clinical features vary; refer to documentation if the note does not clearly describe scleritis.
When to use this code
Use H15.00 when the provider documents scleritis but does not identify anterior, posterior, diffuse, nodular, or necrotizing disease. It also fits cases where the ophthalmology note confirms scleritis without further detail. If later documentation clarifies the subtype, code the more specific diagnosis instead.
Do not use for
Do not use this code for episcleritis, conjunctivitis, or nonspecific eye redness without a scleritis diagnosis. Check documentation when the record names a more specific scleritis type.
Coding tip
If the note only says “scleritis,” H15.00 is appropriate; always look for laterality or subtype details before finalizing.
