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

This code signifies a follow-up encounter for an injury to the radial nerve in the left upper arm. This could involve conditions like nerve contusion, laceration, or compression affecting the nerve's function, occurring after the initial treatment phase.

Apply this code when a patient presents for ongoing care, rehabilitation, or evaluation of complications related to a previously diagnosed radial nerve injury in the left upper arm. This includes visits for physical therapy, re-evaluation of nerve function, or management of persistent symptoms.

• Ensure documentation clearly specifies "left arm" and "upper arm level" for the radial nerve injury.
• Confirm the encounter is for subsequent care, not the initial treatment of the injury.
• Pair with an external cause code (e.g., W00-Y38) to describe the mechanism of injury, if known and relevant to the subsequent encounter.
