ICD-10 Code H31.09 – Other chorioretinal scars (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.09 – Other chorioretinal scars
What it is
H31.09 identifies chorioretinal scarring in the back of the eye that is not classified elsewhere. Use it when the record describes residual scar tissue involving the choroid and retina.
Clinical signs
Findings may include visible retinal or choroidal scar lesions on eye exam or imaging. Clinical features vary; refer to documentation for the cause, location, and laterality if recorded.
When to use this code
Use this code when the provider documents other chorioretinal scars as the diagnosis or a persistent sequela of prior inflammation, injury, or disease. It may also fit follow-up visits when the scar remains clinically relevant. Check documentation for the exact ocular condition and whether a more specific code applies.
Do not use for
Do not use it for active chorioretinal inflammation, retinal detachment, or other retinal disorders with a different documented diagnosis. Do not assign it when the chart only notes nonspecific eye changes; check documentation.
Coding tip
Confirm that the provider documents a scar, not active disease, and code the specific eye condition first if a more precise diagnosis is available.
