Assault by unarmed brawl or fight, initial encounter

This code signifies an injury sustained as a direct result of physical violence involving multiple individuals without the use of weapons. The patient was a participant in or victim of a physical altercation that did not involve firearms, knives, or other implements.

Apply this code when documenting injuries from a street fight, bar brawl, or similar unarmed group confrontation. It is appropriate for the initial medical evaluation and treatment of injuries sustained during such an event.

• Ensure documentation clearly states the absence of weapons and the nature of the altercation.
• Always assign an external cause code for the specific injury sustained (e.g., fracture, contusion).
• Verify the encounter type (initial, subsequent, sequela) to select the correct seventh character.
