Injury of visual cortex, unspecified side, sequela

This code signifies a long-term effect or complication resulting from a past injury to the visual cortex, the part of the brain responsible for processing visual information. This could manifest as persistent visual field defects, cortical blindness, or other visual processing impairments that are a direct consequence of the original trauma. The specific side of the visual cortex affected is not documented or is unknown.

Apply this code when documenting a patient presenting with a current visual impairment that is a residual effect of a previously sustained injury to the visual cortex. The medical record should clearly indicate that the visual deficit is a sequela, meaning it is a late effect of an earlier injury, and the specific side of the brain affected is not specified.

• Always sequence the sequela code first, followed by a code describing the specific nature of the sequela (e.g., H53.4x for visual field defects).
• Ensure documentation explicitly states the visual impairment is a "sequela," "late effect," or "residual effect" of a prior visual cortex injury.
• Avoid using this code for acute injuries; use appropriate acute injury codes from the S04.04- series for initial encounters.
