ICD-10 Code H31.0 – Chorioretinal Scars (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.0 – Chorioretinal scars
What it is
H31.0 identifies scarring in the choroid and retina, usually left after prior inflammation, injury, or other retinal disease. It describes a healed or chronic structural change rather than an active eye disorder.
Clinical signs
Findings may include visible chorioretinal scarring on fundus exam, pigmentary change, or areas of retinal atrophy. Vision effects vary; clinical features vary; refer to documentation.
When to use this code
Use H31.0 when the record documents chorioretinal scars as the diagnosis or as a relevant past condition affecting the eye. It fits cases where the provider describes residual scar tissue after a prior retinal or choroidal process. If the note only mentions an active infection, inflammation, or retinal detachment, code the active condition instead.
Do not use for
Do not use this code for active chorioretinal inflammation, retinal tears, or detached retina. If the documentation does not clearly state scarring, check documentation.
Coding tip
Confirm the provider specifically documents chorioretinal scar or scarred lesion before assigning H31.0.
