ICD-9-CM 354.3 is a billable medical code that can be used to specify a diagnosis on a reimbursement claim.¹ A lesion of the radial nerve according to The Guide for Physical Therapists Practice falls under Impairments/ Peripheral Nerve Injury. The preferred practice pattern for lesion of the radial nerve is 5F, impaired peripheral nerve integrity and muscle performance associated with peripheral nerve injury. Lesion of the radial nerve as described in Therapeutic Exercise Foundations and Techniques is the impairment of the radial nerve due to entrapment.⁴ Clinical features include weakness of elbow extension, elbow flexion, supination of the forearm, wrist and finger extension, and thumb abduction. Sensation may be impaired over regions of the dorsal area of the forearm and hand. Common sites of compression or traumatic injury are under the extensor carpi radialis brevis or may occur with a radial head fracture.⁴ The radial nerve wraps around the humerus, and runs anteriorly around the lateral epicondyle at the elbow then it divides into deep and superficial branches. The superficial branch follows the lateral side of the radius all the way to the hand.⁴ The deep
