Activity, rough housing and horseplay

This diagnosis code indicates an injury or adverse effect resulting from boisterous, playful, or physically unrestrained activity. It specifically refers to actions like wrestling, mock fighting, or other energetic and often uncoordinated interactions that lead to an incident.

This code is appropriate when documenting injuries sustained during recreational activities characterized by rough physical contact or exuberant play. Examples include children or adults getting hurt while playing tag aggressively, wrestling playfully, or engaging in other forms of horseplay.

• Always assign this code as an external cause code (V00-Y99) to describe the circumstances of the injury, not as a primary diagnosis.
• Pair this code with a primary diagnosis code (e.g., fracture, sprain, contusion) that describes the actual injury sustained.
• Ensure documentation clearly specifies the activity as roughhousing or horseplay to support the use of this specific external cause code.
