Other retinal disorders in diseases classified elsewhere

This code signifies a retinal disorder that is a manifestation of, or secondary to, another underlying systemic disease. It is used when the specific retinal condition is not otherwise classified and is directly linked to a primary illness.

Apply this code when documentation clearly states a retinal disorder (e.g., retinal vasculitis, retinal detachment) is secondary to a systemic disease such as diabetes, lupus, or sarcoidosis, and a more specific retinal code is unavailable. The medical record must explicitly link the retinal condition to the underlying systemic disease.

• Always sequence the underlying systemic disease code first, followed by this code.
• Ensure the documentation specifies the type of retinal disorder and its causal link to the primary disease.
• Do not use if a more specific ICD-10-CM code exists for the particular retinal manifestation of the underlying disease (e.g., diabetic retinopathy).
