Injury of radial nerve at upper arm level, unsp arm, subs

This code signifies a documented injury to the radial nerve in the upper arm, where the specific arm (left or right) is not identified. This injury is being addressed during a follow-up visit after the initial treatment of the nerve damage.

Use this code for subsequent encounters when a patient presents for ongoing management, evaluation, or treatment of a radial nerve injury in the upper arm, and the medical record does not specify which arm was affected. This includes scenarios like physical therapy, medication adjustments, or follow-up imaging after the initial injury has been addressed.

• Ensure documentation clearly indicates a "subsequent encounter" for the injury.
• Only use this code when the affected arm is truly unspecified in the medical record. If laterality is documented, a more specific code should be used.
• Always sequence this code after any applicable external cause codes (e.g., for the original injury).
