ICD-10 Code H15.012 – Anterior scleritis, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.012 – Anterior scleritis, left eye
What it is
H15.012 identifies inflammation of the sclera, the white outer coat of the eye, limited to the anterior portion and the left eye. It is used when documentation specifically states anterior scleritis on the left.
Clinical signs
Typical findings include a painful, red eye with deep scleral injection and tenderness. Clinical features vary; refer to documentation for laterality and whether the inflammation is anterior.
When to use this code
Use this code when the provider documents anterior scleritis in the left eye, including ophthalmology assessments or problem lists. You may also use it when the note clearly identifies left-sided anterior scleral inflammation, even if the encounter is for evaluation or follow-up.
If the record only says “scleritis” without laterality or location, check documentation before coding. Confirm that the condition is not described as another eye disorder with similar redness or pain.
Do not use for
Do not use this code for episcleritis, conjunctivitis, or unspecified scleritis. If the documentation does not confirm the left eye or anterior location, check documentation.
Coding tip
Verify both the anatomic site and laterality in the provider note before assigning H15.012.
