About Y35.899

Y35.899 is the ICD-10-CM diagnosis code for legal intervention involving other specified means, unspecified person injured. It belongs to category Y35 (legal intervention), block Y35-Y38 (legal intervention, operations of war, military operations, and terrorism) 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 Y35.89, choose Y35.899 (unspecified person injured) only when documentation doesn't support a more specific option: law enforcement official injured (Y35.891), bystander injured (Y35.892) and suspect injured (Y35.893).

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 was added in FY2022, effective October 1, 2021.
