About Y08.89

Y08.89 is the ICD-10-CM diagnosis code for assault by other specified means. It belongs to category Y08 (assault by other specified means), 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 Y08.8, choose Y08.89 (other specified means) only when documentation doesn't support a more specific option: crashing of aircraft (Y08.81).

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.
