Injury of visual cortex, unspecified side, subs

This code signifies an injury to the visual cortex, the part of the brain responsible for processing visual information, when the specific side (left or right) of the injury is not documented. This injury could result from trauma, stroke, or other neurological events affecting the occipital lobe.

This code is appropriate for encounters following the initial treatment of a visual cortex injury, where the patient is receiving active treatment for the sequelae of the injury. Documentation should clearly indicate an ongoing treatment phase for the injury itself, rather than just routine follow-up or resolution of the condition.

• Ensure documentation specifies "subsequent encounter" and ongoing treatment for the injury.
• Avoid using this code if the laterality (left or right) of the visual cortex injury is clearly documented; instead, use the more specific S04.041D or S04.042D.
• Do not use for initial encounters (use S04.049A) or for sequelae (use S04.049S).
