Crushing injury of multiple sites of upper limb

This code signifies a severe traumatic injury to the upper limb resulting from compression or crushing forces affecting multiple distinct anatomical areas. It indicates significant tissue damage, potentially involving bone, muscle, nerves, and blood vessels, across more than one site within the arm, forearm, wrist, or hand.

Apply this code when documentation clearly states a crushing mechanism of injury impacting several regions of the upper extremity, such as a crush to both the forearm and hand, or the shoulder and upper arm. This is appropriate for acute traumatic events where the force applied causes widespread damage across multiple sites.

• Ensure the documentation specifies "multiple sites" within the upper limb; single-site crushing injuries have more specific codes.
• Do not use for open wounds unless the crushing component is the primary and most severe injury.
• Consider external cause codes (E-codes) to describe the circumstances of the injury.
