Assault by other specified means (Y08)

The ICD-10 code Y08 and its subcategories classify assaults caused by specific non-firearm means, such as sports equipment or other targeted objects. These codes are used to document injuries resulting from assaults involving items like hockey sticks, baseball bats, or other specified weapons and methods.

This section includes detailed codes such as Y08.01 for assault by strike with a hockey stick and Y08.02 for assault by strike with a baseball bat, which are essential for precisely capturing injuries from sports-related assaults. The related codes with 7th characters (e.g., Y08.02XA for initial encounter) provide additional context about the timing of treatment. Additionally, Y08.81 covers assault by crashing of aircraft, noted as a war-related injury. The broad category Y08.89 includes assaults involving corrosive substances, electric devices, physical restraint, spitting, and other specified means, helping medical coders differentiate between types of assaults by uncommon mechanisms. Using these codes helps ensure detailed, accurate reporting when the assault is by a specific non-firearm cause in ICD-10 coding.

Instructional Notations

7th Character Note

Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

  • The appropriate 7th character is to be added to each code from category Y08
