Other chorioretinal scars, bilateral

This code signifies the presence of non-specific scarring affecting both the choroid and retina. These scars represent healed lesions from various past chorioretinal inflammatory, infectious, or traumatic events, without further specification of their origin.

Apply this code when documentation indicates bilateral chorioretinal scarring that is not further characterized by a specific etiology (e.g., toxoplasmosis, histoplasmosis). This is appropriate when the physician notes "bilateral chorioretinal scars, unspecified" or similar.

• Ensure the documentation explicitly states "bilateral" involvement. If only one eye is affected, use the appropriate laterality code.
• Avoid using this code if a more specific cause of the chorioretinal scar is identified (e.g., H31.01- for toxoplasmosis).
• Always review the entire ophthalmology note for any additional details that might lead to a more precise diagnosis.
