Disord of visual pathways in vascular disord, right side

This code signifies visual pathway dysfunction on the right side of the brain or optic nerve, specifically caused by a vascular event such as a stroke, hemorrhage, or ischemia. It indicates that the impairment in vision or visual processing is a direct consequence of compromised blood supply to the visual system.

Use this code when documentation clearly links a patient's right-sided visual pathway disorder (e.g., right homonymous hemianopsia, right optic neuropathy) to an underlying vascular etiology. This often follows a cerebrovascular accident (CVA) affecting the optic radiations, optic tract, or visual cortex on the left side, or a vascular event directly impacting the right optic nerve.

• Ensure the documentation explicitly states the vascular origin of the visual pathway disorder.
• Specify the laterality (right side) as indicated by the code.
• Code the underlying vascular condition (e.g., cerebral infarction, cerebral hemorrhage) as the primary diagnosis if it is the acute reason for the encounter.
