Neurology & Pain Management Coding Alert

Hint: Start by distinguishing from F-wave studies. You might turn to Appendix J of the CPT® manual most often to review the maximum number of nerve conduction studies you typically report for specific indications. Don't overlook the next column that addresses H-reflex (or Hoffmann's reflex) studies, however, because these tests have specific considerations to keep in mind while avoiding denials.1. Learn Difference Between Tests H-reflex and F-wave studies both test the patient's late response reflex and evaluate the entire length of a nerve, but in different ways. F-waves assess motor nerve fiber function along a nerve and are generally performed in conjunction with conventional motor nerve conduction studies. H-reflex studies, however, involve both the sensory and motor nerve fibers and test both connections in the spinal cord. "Both late response tests can be valuable in evaluating nerve conduction in the more proximal portions of the nerve, meaning you're studying conduction [...]
