Injury of radial nerve at wrs/hnd lv of unsp arm, subs

This code signifies a documented injury to the radial nerve occurring at the wrist or hand level of an unspecified arm. This injury typically results in sensory deficits (e.g., numbness, tingling) and/or motor weakness (e.g., difficulty with wrist extension, thumb abduction) in the distribution of the radial nerve. The "subsequent encounter" designation indicates that the patient is receiving routine care during the healing or recovery phase of the injury.

Apply this code for follow-up visits where a patient is being managed for a previously diagnosed radial nerve injury at the wrist or hand, and the specific arm (left or right) was not documented. This includes scenarios such as wound care, physical therapy, medication management, or re-evaluation of nerve function during the healing process. Do not use for the initial treatment of the injury.

• Ensure documentation clearly states the injury is to the radial nerve at the wrist or hand level.
• Verify the encounter type is for follow-up care, not the initial injury treatment.
• If the laterality (left or right arm) is specified in the documentation, a more specific code should be used.
