ICD-10 Code H17.811 – Minor opacity of cornea, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H17.811 – Minor opacity of cornea, right eye
What it is
This code identifies a small or limited corneal opacity in the right eye. It indicates a cloudy area of the cornea that may affect clarity of vision, depending on size and location.
Clinical signs
Findings may include a visible corneal haze, scar, or localized opacity on eye examination. Clinical features vary; refer to documentation.
When to use this code
Use H17.811 when the provider documents a minor opacity or small corneal scar specifically in the right eye. Apply it for unilateral findings when the record does not describe a more extensive corneal disorder or a different primary diagnosis.
Do not use for
Do not use this code for left-eye or bilateral corneal opacity, or for a corneal condition documented as more than minor. Check documentation if the note describes ulcer, edema, dystrophy, or another specific corneal disease.
Coding tip
Always confirm laterality and the exact wording of “minor opacity” before assigning H17.811.
