Focal chorioretinal inflammation of posterior pole, left eye

This code signifies an inflammatory process affecting the choroid and retina specifically located in the posterior pole of the left eye. This inflammation is localized rather than diffuse and can be caused by various infectious or autoimmune etiologies.

Apply this code when documentation clearly indicates a focal chorioretinal inflammatory lesion confined to the posterior pole of the left eye. This diagnosis is typically made following ophthalmoscopic examination, fundus photography, or optical coherence tomography (OCT) showing a discrete inflammatory focus.

• Ensure the documentation specifies "focal" and "posterior pole" to differentiate from more generalized or peripheral chorioretinitis.
• Verify the laterality is explicitly stated as "left eye" to avoid incorrect coding.
• Look for an underlying cause (e.g., infectious agent, autoimmune disease) which may require an additional code to fully describe the patient's condition.
