Injury of median nerve at forearm level, left arm, init

This code signifies damage to the median nerve specifically within the forearm region of the left arm. This injury can result in sensory deficits (numbness, tingling) and/or motor weakness in the hand and fingers supplied by the median nerve.

Apply this code for patients presenting with a new injury to the median nerve in their left forearm, such as from a laceration, crush injury, or fracture. It is appropriate for the initial assessment and treatment of this specific nerve damage.

• Ensure documentation clearly specifies the left arm and the forearm level of the median nerve injury.
• Confirm this is the initial encounter for the injury; subsequent care would use a different encounter character.
• Look for associated injuries, such as open wounds or fractures, and code them separately as appropriate.
