Injury of median nerve at wrs/hnd lv of left arm, init

This code signifies damage to the median nerve in the left wrist or hand region. This injury can result in sensory deficits (numbness, tingling) and motor weakness (difficulty with thumb opposition and finger flexion) in the areas supplied by the median nerve. The "initial encounter" designation indicates that this is the first time the patient is receiving active treatment for this specific injury.

Use this code for a patient presenting with a newly diagnosed median nerve injury affecting the left wrist or hand, such as from a laceration, crush injury, or severe sprain. It is appropriate for the initial visit where the injury is evaluated, diagnosed, and the initial treatment plan is established.

• Ensure documentation clearly specifies the left arm and the wrist/hand level of the median nerve injury.
• Verify that this is indeed the initial encounter for active treatment of this specific injury.
• Look for associated codes for the underlying cause of the injury (e.g., laceration, fracture) to provide a complete clinical picture.
