Injury of optic nerve, right eye, initial encounter

This code signifies damage to the right optic nerve, which transmits visual information from the eye to the brain. Such an injury can result in partial or complete vision loss in the affected eye. It often stems from trauma, compression, or inflammation impacting the nerve pathway.

Apply this code for a patient presenting with a newly diagnosed or acutely treated injury to their right optic nerve. Documentation should clearly state the right eye involvement and the initial phase of care for the injury. This code is appropriate when the patient is receiving active treatment for the optic nerve damage.

• Ensure laterality (right eye) is explicitly documented; do not default if not specified.
• Verify the encounter type is "initial" for active treatment of the injury. Subsequent encounters will require different seventh characters.
• Code any associated external cause of injury (e.g., fall, assault) and place of occurrence codes.
