ICD-10 Code H18.529 – Epithelial (juvenile) corneal dystrophy, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.529 – Epithelial (juvenile) corneal dystrophy, unspecified eye
What it is
This code identifies a corneal dystrophy affecting the epithelial layer of the cornea, with juvenile onset or inherited pattern implied by the diagnosis. Use it when the record names epithelial (juvenile) corneal dystrophy and does not specify the eye.
Clinical signs
Clinical features vary; refer to documentation. Standard descriptions may include recurrent corneal erosions, visual disturbance, or irregular corneal surface changes seen on eye examination.
When to use this code
Use H18.529 when the clinician documents epithelial (juvenile) corneal dystrophy and laterality is not stated. It also fits when the condition is confirmed but the note does not identify right, left, or bilateral eye. Check documentation if the record uses another corneal dystrophy subtype.
Do not use for
Do not use this code for corneal dystrophies with a different layer, type, or named subtype. If the chart specifies another eye or a more precise diagnosis, code that instead.
Coding tip
Look for laterality and exact dystrophy wording in the ophthalmology note before assigning the unspecified-eye code.
