About W50.4
W50.4 is the ICD-10-CM diagnosis code for accidental scratch by another person. It belongs to category W50 (accidental hit, strike, kick, twist, bite or scratch by another person), block W50-W64 (exposure to animate mechanical forces) 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 W50 (accidental hit, strike, kick, twist, bite or scratch by another person), W50.4 is specifically for accidental scratch by another person. Related codes cover hit or strike by another person (W50.0), kick by another person (W50.1), twist by another person (W50.2) and bite by another person (W50.3).
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.
