ICD-10 Code H15.013 – Anterior scleritis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.013 – Anterior scleritis, bilateral
What it is
H15.013 identifies inflammation of the sclera, the white outer coat of the eye, affecting the front portion in both eyes. Use it when documentation clearly states bilateral anterior scleritis.
Clinical signs
Typical findings include eye pain, redness, tenderness, and visible scleral inflammation in the anterior segment. Clinical features vary; refer to documentation for laterality and whether the condition is diffuse, nodular, or necrotizing.
When to use this code
Assign this code when the provider documents anterior scleritis in both eyes, or bilateral scleral inflammation limited to the anterior portion. It is appropriate for confirmed diagnoses in outpatient, inpatient, or specialty eye care records. Check documentation if the note does not clearly specify bilateral involvement.
Do not use for
Do not use this code for episcleritis, conjunctivitis, or unspecified scleritis without bilateral anterior detail. If the record only says “scleritis” or laterality is unclear, check documentation.
Coding tip
Verify both laterality and the anterior location before selecting H15.013.
