Nerve conduction study codes 95900, 95903, 95904, and H–reflex codes95934 and 95936 have been deleted. Seven new nerve conduction codes (95907–95913) have been established. In the new coding structure, the unit of service in codes 95907–95913 is the number of nerve conduction studies performed; whereas the unit of service in previous codes 95900–95904 was each nerve. For the purposes of coding, a single conduction study is defined as a sensory conduction test, a motor conduction test with an F–wave or without an F wave test, or an H–reflex test. Each type of nerve conduction study is counted only once when multiple sites on the same nerve are stimulated or recorded. The numbers of these separate tests should be added to determine which code to use.
- 95907 Nerve conduction studies; 1-2 studies
- 95908 Nerve conduction studies, 3-4 studies
- 95909 Nerve conduction studies, 5-6 studies
- 95910 Nerve conduction studies, 7-8 studies
- 95911 Nerve conduction studies, 9-10 studies
- 95912 Nerve conduction studies, 11-12 studies
- 95913 Nerve conduction studies, 13 or more studies
The following table provides a reasonable maximum number of studies performed per diagnostic category necessary for a physician to arrive at a diagnosis in 90% of patients with that final diagnosis. The numbers in each column represent the number of studies recommended. The appropriate number of studies to be performed is based upon the physician’s discretion.
