About Y03.8
Y03.8 is the ICD-10-CM diagnosis code for other assault by crashing of motor vehicle. It belongs to category Y03 (assault by crashing of motor vehicle), block X92-Y09 (assault) and chapter 20 (external causes of morbidity). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.
Within Y03, choose Y03.8 (Other assault by crashing of motor vehicle) only when documentation doesn't support a more specific option: assault by being hit or run over by motor vehicle (Y03.0).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
