Transient retinal artery occlusion, bilateral

This code signifies a temporary blockage of blood flow in the arteries supplying the retina, affecting both eyes. It indicates an acute, transient episode of retinal ischemia without permanent damage or infarction.

Apply this code when documentation specifies a transient retinal artery occlusion that has resolved, with the laterality explicitly stated as bilateral. This is often seen in cases of amaurosis fugax or other temporary vision loss events attributed to retinal arterial compromise in both eyes.

• Ensure the documentation clearly states "transient" and "bilateral" to support this specific code.
• Do not use this code for permanent occlusions or if only one eye is affected; use more specific codes for those scenarios.
• Consider sequencing this code with codes for underlying systemic conditions (e.g., atherosclerosis, carotid artery disease) that may contribute to retinal artery occlusion.
