Focal chorioretin inflam, macular or paramacular, bilateral

This code signifies an inflammatory process affecting both eyes, specifically within the macula or the area immediately surrounding it (paramacular region) of the choroid and retina. This inflammation is localized rather than diffuse and can be caused by various infectious or non-infectious etiologies.

Apply this code when documentation clearly indicates bilateral focal chorioretinal inflammation impacting the macular or paramacular area. This diagnosis is typically made by an ophthalmologist based on funduscopic examination, optical coherence tomography (OCT), or fluorescein angiography findings.

• Ensure the documentation specifies "focal" and not diffuse inflammation, and explicitly states involvement of the macula or paramacular region.
• Confirm that both eyes are affected; if only one eye is involved, a laterality-specific code should be used.
• Look for underlying causes (e.g., infectious agents, autoimmune conditions) that may require additional codes to fully describe the patient's condition.
