2026 ICD-10-CM Diagnosis Code H31.091 – Other chorioretinal scars, right eye
What it is
This code identifies a chorioretinal scar located in the right eye that is not classified elsewhere. It reflects a healed or residual lesion involving the choroid and retina.
Clinical signs
Findings may include a visible chorioretinal scar on fundus exam, often with pigmentary change or localized retinal atrophy. Clinical features vary; refer to documentation.
When to use this code
Use H31.091 when the provider documents a chorioretinal scar in the right eye and does not specify a more exact diagnosis. It is appropriate for residual scarring from prior inflammation, infection, trauma, or other ocular disease when the record supports a right-eye location.
Do not use for
Do not use this code for active chorioretinal inflammation, macular degeneration, or scars in the left eye or both eyes. Check documentation if the laterality or cause is unclear.
Coding tip
Verify laterality in the ophthalmology note before assigning H31.091.
