Injury of visual cortex, left side, initial encounter

This code signifies a traumatic injury affecting the visual cortex located in the left cerebral hemisphere. Such an injury can lead to various visual field deficits, including hemianopsia or quadrantanopsia, depending on the specific area and extent of damage. It represents the initial phase of treatment for this type of brain injury.

Apply this code for a patient presenting with an acute injury to the left visual cortex, typically due to trauma such as a concussion, contusion, or penetrating injury. Documentation should clearly specify the left side of the brain and the visual cortex as the affected area, along with evidence of an initial encounter for treatment.

• Ensure documentation explicitly states "left side" and "visual cortex" to support this specific code.
• Verify the encounter is truly the "initial encounter" for this specific injury; subsequent care would require a different seventh character.
• Consider co-reporting with external cause codes (V, W, X, Y codes) to describe the circumstances of the injury.
