ICD-10 Code H15.09 – Other scleritis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.09 – Other scleritis
What it is
Use this code for scleritis that is documented as “other” and does not fit a more specific subtype. It indicates inflammation of the sclera, the white outer layer of the eye.
Clinical signs
Typical findings include deep eye pain, redness, and tenderness, often with pain on eye movement. Clinical features vary; refer to documentation.
When to use this code
Use H15.09 when the provider diagnoses scleritis but does not specify anterior, posterior, or another more defined category. It also fits cases where the note clearly states “other scleritis” or leaves the subtype unspecified. Check documentation if the record suggests a different inflammatory eye disorder.
Do not use for
Do not use this code for episcleritis, conjunctivitis, or nonspecific eye redness without a documented scleritis diagnosis. If the chart names a more specific scleritis type, code that instead.
Coding tip
Code from the provider’s exact wording and confirm whether the scleritis subtype is specified before defaulting to H15.09.
