ICD-10 Code H15.043 – Scleritis with corneal involvement, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.043 – Scleritis with corneal involvement, bilateral
What it is
This code identifies inflammation of both sclerae with extension to the cornea. Use it when the record clearly documents bilateral scleritis affecting the cornea.
Clinical signs
Typical findings include deep ocular pain, redness, and tenderness, with corneal involvement noted on exam. Clinical features vary; refer to documentation.
When to use this code
Assign H15.043 when the provider documents scleritis in both eyes and specifically states corneal involvement. Use the bilateral code only if both sides are affected; otherwise, check for a unilateral or unspecified option.
Do not use for
Do not use this code for episcleritis, isolated keratitis, or scleritis without corneal involvement. If the laterality or corneal involvement is unclear, check documentation.
Coding tip
Confirm both laterality and corneal involvement in the assessment before coding.
