Accidental hit, strike, kick, twist, bite or scratch by another person (W50)

The W50 ICD-10 codes are used to classify injuries resulting from accidental physical interactions caused by another person, such as being hit, kicked, twisted, bitten, or scratched without intent to harm. These codes help specify the nature of the incident and the injury's treatment phase, such as initial encounter, follow-up, or ongoing complications.

The main category W50 covers general accidental hits, strikes, kicks, twists, bites, or scratches inflicted by another person. For example, the code W50.0 pertains specifically to accidental hits or strikes and includes detailed subcodes like W50.0XXA for initial care after being accidentally struck during sports activities. Injuries from accidental kicks fall under W50.1, while twists, bites, and scratches correspond to W50.2, W50.3, and W50.4, respectively. Notably, W50.3 relates to human bites and their various wound locations, using synonyms like "human bite" or "bite wound," aiding accurate coding for these specific wounds. These codes assist both healthcare providers and coders in documenting unintentional injuries caused by others, ensuring clarity for clinical and billing purposes.
