Injury of visual cortex, right side, sequela

This code signifies a long-term or late effect resulting from a previous injury to the visual cortex located in the right hemisphere of the brain. This could manifest as persistent visual field defects, cortical blindness, or other visual processing impairments that are no longer in the acute phase of injury. The sequela indicates that the initial injury has resolved, but its lasting effects remain.

Use this code when documenting a patient presenting with chronic visual deficits directly attributable to a past injury of the right visual cortex. The medical record should clearly state that the visual impairment is a residual effect of a previous trauma, and the acute phase of the injury has passed. This code is appropriate for follow-up visits addressing these long-term complications.

• Always sequence the sequela code first, followed by any associated manifestations of the sequela (e.g., specific visual field defects).
• Ensure documentation explicitly states "sequela," "late effect," or "due to previous injury" to support the use of this code.
• Distinguish from acute injuries (S04.041A, D) which are used during the initial treatment or active healing phase.
