ICD-10-CMInjury of radial nerve at upper arm level, right arm, initial encounter
This code signifies damage to the radial nerve in the upper arm region of the patient's right arm, occurring as the initial presentation of the injury. This type of injury can result in motor and sensory deficits in the forearm and hand, impacting wrist extension, finger extension, and sensation over the dorsal hand.
Apply this code for a patient presenting with a newly diagnosed radial nerve injury in the right upper arm, such as from a humeral shaft fracture, direct trauma, or compression. This is appropriate for the initial evaluation and treatment of the acute injury.
