ICD-10 Code H15.002 – Unspecified scleritis, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.002 – Unspecified scleritis, left eye
What it is
H15.002 identifies scleritis affecting the left eye when the type is not further specified. It refers to inflammation of the sclera, the tough outer coat of the eye.
Clinical signs
Typical findings include a painful, red eye with tenderness and possible photophobia. Clinical features vary; refer to documentation if the record does not clearly describe the scleral inflammation.
When to use this code
Use H15.002 when the provider documents scleritis in the left eye but does not specify anterior, posterior, or other subtype. It also fits when laterality is clear and the note supports scleral inflammation without more detail. If the record is ambiguous, check documentation before coding.
Do not use for
Do not use this code for episcleritis, conjunctivitis, or other nonscleral eye redness. It is also incorrect when the chart specifies a different eye or a more specific scleritis type.
Coding tip
Verify both laterality and the word “scleritis” in the provider note before assigning H15.002.
