Injury to visual cortex

This code signifies damage to the visual cortex, the part of the brain responsible for processing visual information. Such injuries can result from trauma, stroke, or other neurological insults, leading to various visual field defects or cortical blindness. The specific location and extent of the lesion determine the clinical presentation.

Use this code for documented cases of injury or damage to the occipital lobe, specifically affecting the visual cortex. Supporting documentation should include imaging reports (e.g., MRI, CT) confirming the lesion's location and clinical notes detailing visual disturbances attributable to cortical damage.

• Differentiate from optic nerve or retinal injuries; this code is specific to cortical damage.
• Always code the underlying cause of the injury (e.g., head injury, stroke) first, followed by this code as a secondary diagnosis.
• Ensure documentation specifies "visual cortex" or "occipital lobe with visual deficits" to support this specific code.
