Transient visual loss, bilateral

This code represents a temporary, reversible loss of vision affecting both eyes. It indicates that the visual disturbance is not permanent and resolves spontaneously, often within minutes. This condition can be a symptom of various underlying systemic or ocular issues.

Use this code when documentation specifies a transient visual obscuration or amaurosis fugax affecting both eyes. This diagnosis is often supported by patient history detailing episodes of temporary vision loss and a physical examination that may or may not reveal an underlying cause. It is crucial that the visual loss is explicitly stated as bilateral and temporary.

• Differentiate from monocular transient visual loss (amaurosis fugax), which has a different code.
• Always code any underlying systemic or ocular conditions causing the transient visual loss, such as carotid artery disease or migraine, as primary or secondary diagnoses.
• Ensure the documentation clearly states the bilateral nature and transient characteristic of the visual loss to support this specific code.
