Laceration of ulnar artery at wrs/hnd lv of right arm, init

This code signifies a laceration, or cut, of the ulnar artery specifically in the right wrist or hand region. It indicates an open injury to this major blood vessel, requiring medical attention. The "initial encounter" designation means this code is used for the first time a patient is seen for this specific injury.

Apply this code when documenting an acute injury involving a deep cut to the ulnar artery in the right wrist or hand, such as from a sharp object. It is appropriate for the initial visit where the injury is diagnosed and treatment, like surgical repair, is initiated.

• Ensure the documentation specifies the right arm and the ulnar artery, not the radial.
• Verify the injury is a laceration and not another type of vascular injury.
• Confirm this is the initial encounter for this specific injury; subsequent care would use a different seventh character.
