AMA CPT® Assistant - 2008 Issue 2 (February)
Nerve Conduction Studies (95900-95904) (February 2008)
February 2008 page 2 Coding Communication:Nerve Conduction Studies (95900-95904) The following AMA responses to six commonly asked questions help to clarify concerns about coding for nerve conduction studies. Why are nerve conduction studies performed? Nerve conduction studies (NCSs) are performed to aid in the diagnoses of diseases and injuries of the peripheral nervous system. Nerve conduction studies assess the speed (conduction velocity and/or latency), size (amplitude), and shape of the response to an applied stimulus. Pathological findings include conduction slowing, conduction block, absent nerve response, and/or low amplitude response. NCS results can also assess the degree of demyelination and...

Article Overview
This article explains how nerve conduction study coding was being discussed in a February 2008 CPT Assistant communication. It is aimed at coders, billers, and clinical documentation staff who need a better understanding of the CPT code set, nerve and branch groupings in Appendix J, and the general types of questions addressed by AMA guidance on electrodiagnostic testing.
Why This Topic Matters
Nerve conduction study reporting can depend on how nerves, branches, and study locations are characterized in CPT guidance. This article is relevant for people who need to interpret AMA clarification material and understand the broader coding context for electrodiagnostic services.
Article Sections
-
Coding Communication: Nerve Conduction Studies
Introduces the AMA communication and the coding questions it addresses about nerve conduction studies and electrodiagnostic medicine.
-
Purpose and performance of nerve conduction studies
Describes the general purpose of nerve conduction studies and the broad way the tests are performed for peripheral nervous system evaluation.
-
Reporting studies on multiple places along a nerve and branches
Discusses how the article frames reporting when testing involves more than one location or branch within the same nerve pathway.
-
Appendix J and nerve branch definitions
Summarizes the role of Appendix J in identifying nerves and branches referenced in the CPT codebook.
-
Parenthetical note on reporting a single study
Addresses the article’s discussion of the parenthetical note associated with reporting nerve conduction studies in the CPT code series.
-
Typical number of studies for a diagnosis
Covers the article’s final discussion of study counts commonly associated with a diagnosis and how that topic is presented in the codebook context.
