Injury of ulnar nerve at wrs/hnd lv of right arm, init

This code signifies a traumatic injury to the ulnar nerve specifically located at the wrist or hand level of the patient's right arm. This type of injury can result in sensory deficits (numbness, tingling) and/or motor weakness in the areas innervated by the ulnar nerve distal to the injury site.

Apply this code for initial encounters where a patient presents with a new injury to the ulnar nerve in the right wrist or hand, such as from a laceration, crush injury, or fracture affecting this specific nerve segment. It is appropriate for the first visit for this particular injury.

• Ensure documentation clearly specifies the right arm and the wrist/hand level of the ulnar nerve.
• Verify the encounter is indeed the "initial encounter" for this specific injury.
• Look for associated codes for open wounds, fractures, or other injuries if present.
