ICD-10 Code H17.82 – Peripheral opacity of cornea (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H17.82 – Peripheral opacity of cornea
What it is
H17.82 identifies a peripheral corneal opacity, meaning a cloudy or scarred area at the edge of the cornea. Use it when documentation states the opacity is peripheral and not central.
Clinical signs
Findings may include a visible peripheral corneal haze, scar, or white opacity on eye examination. Visual impact varies; clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents peripheral corneal opacity, corneal scar, or localized peripheral clouding of the cornea. It fits cases where the condition is described by location rather than cause. If the record names a different corneal disorder, check documentation before coding.
Do not use for
Do not use H17.82 for central corneal opacity or general corneal clouding without a peripheral location. Check documentation if the note instead describes ulceration, edema, dystrophy, or active infection.
Coding tip
Confirm both the corneal location and the word “opacity” in the provider note before assigning H17.82.
