Injury of visual cortex, right side, initial encounter

This code signifies a traumatic injury affecting the visual cortex located in the right cerebral hemisphere. Such an injury can result in various visual field defects, including cortical blindness or hemianopsia, depending on the extent and specific area of damage. It indicates the initial phase of treatment for this specific neurological trauma.

Apply this code when documentation clearly states an injury to the right visual cortex, often following head trauma, stroke, or other neurological insult. This code is appropriate for the initial encounter where the patient is receiving active treatment for the injury. Supporting documentation should include imaging reports (e.g., CT, MRI) confirming the location of the lesion and neurological examination findings.

• Ensure laterality (right side) is explicitly documented; do not assume.
• Verify the encounter type is "A" for initial encounter; subsequent care will require different seventh characters.
• Always code any associated external cause of injury (e.g., fall, motor vehicle accident) in conjunction with this code.
