S04.011 is the ICD-10-CM diagnosis code for injury of optic nerve, right eye. It belongs to category S04 (injury of cranial nerve), block S00-S09 (injuries to the head) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.
