Injury of visual cortex, right side, subsequent encounter

This code signifies an injury to the visual cortex located in the right cerebral hemisphere, specifically when the patient is receiving subsequent care for the initial injury. Such an injury can result in various visual field defects, including hemianopsia or quadrantanopsia, depending on the extent and location of the damage.

Use this code for follow-up encounters, such as rehabilitation, medication management, or ongoing assessment, for a previously diagnosed injury to the right visual cortex. Documentation should clearly indicate that the patient is beyond the initial acute phase of treatment and is receiving care related to the healing or long-term effects of the injury.

• Ensure the "D" seventh character is appropriate for subsequent care; "A" is for initial encounter and "S" for sequela.
• Always confirm laterality (right vs. left) based on physician documentation.
• Consider co-reporting with codes for specific visual disturbances (e.g., H53.1-, H53.4-) if documented.
