The ICD code R412 is used to code Retrograde amnesia

Retrograde amnesia (RA) is a loss of memory-access to events that occurred, or information that was learned, before an injury or the onset of a disease. RA is often temporally graded, consistent with Ribot's Law: subjects are more likely to lose recent memories that are closer to the traumatic incident than more remote memories.
