ICD-10 Code H17.829 – Peripheral opacity of cornea, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H17.829 – Peripheral opacity of cornea, unspecified eye
What it is
This code identifies a cloudy or scarred area at the edge of the cornea in an unspecified eye. It is used when the record notes peripheral corneal opacity but does not specify laterality.
Clinical signs
Findings may include a visible peripheral corneal haze, scar, or opacity on eye examination. Clinical features vary; refer to documentation for the exact appearance and whether vision is affected.
When to use this code
Use H17.829 when the provider documents peripheral opacity of the cornea and does not specify the eye involved. It also fits when the note describes a peripheral corneal opacity without enough detail for a more specific code. Check documentation if the opacity is linked to another corneal disorder.
Do not use for
Do not use this code for central corneal opacity, corneal edema, or active infection. If the record identifies the right or left eye, choose the laterality-specific code instead.
Coding tip
Confirm both the location and laterality in the ophthalmology note before assigning H17.829.
