ICD-10 Code H31.003 – Unspecified chorioretinal scars, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.003 – Unspecified chorioretinal scars, bilateral
What it is
This code identifies chorioretinal scarring in both eyes when the exact cause or type is not documented. It indicates a healed or residual scar involving the choroid and retina.
Clinical signs
Findings may include visible retinal or chorioretinal scar tissue on examination, sometimes with a history of prior inflammation, infection, or injury. Clinical features vary; refer to documentation.
When to use this code
Use H31.003 when the record documents bilateral chorioretinal scars but does not specify the underlying cause or a more precise diagnosis. Apply it when the provider notes scarring in both eyes and no laterality-specific or etiology-specific code is supported. Check documentation if the note suggests active disease rather than a healed scar.
Do not use for
Do not use this code for unilateral chorioretinal scars or when the chart identifies a specific cause that should be coded instead. Do not use it for active chorioretinal inflammation without documented scarring.
Coding tip
Confirm both-eye involvement and whether the provider documented an unspecified scar rather than a more specific retinal or choroidal diagnosis.
