ICD-10 Code H18.469 – Peripheral corneal degeneration, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.469 – Peripheral corneal degeneration, unspecified eye
What it is
This code identifies a peripheral degeneration of the cornea in an unspecified eye. It describes a non-specific corneal change near the edge of the cornea, without laterality documented.
Clinical signs
Clinical features vary; refer to documentation. Findings may include peripheral corneal thinning, opacity, or degenerative change noted on eye examination.
When to use this code
Use H18.469 when the provider documents peripheral corneal degeneration but does not specify right or left eye. It is also appropriate when the record describes a peripheral corneal degenerative process without a more specific diagnosis. Check documentation if another corneal disorder is named.
Do not use for
Do not use this code for corneal degeneration with documented laterality or for a different corneal disease such as ulcer, dystrophy, or infection. Check documentation if the note is unclear.
Coding tip
If the chart identifies the affected eye, choose the laterality-specific code instead of the unspecified-eye code.
