Autonomic Nervous System Function Testing (September 2020)
September 2020 pages 7-10 Autonomic Nervous System Function Testing Current Procedural Terminology (CPT®) codes 95921-95924 and 95943 in the Autonomic Function Tests subsection of the Medicine section of the CPT code set were identified by the American Medical Association (AMA)/Specialty Society Relative Value Scale (RVS) Update Committee (RUC) through a screening process for codes with high-volume growth and that are reported by different specialty(ies) other than the specialty(ies) surveyed for physician work recommendations in the Medicare program. This article provides clarity on the intent of these codes and the required service components for correct reporting. Autonomic Function Tests...

Article Overview
This CPT Assistant article reviews autonomic nervous system function testing and explains how the related CPT codes fit within the Autonomic Function Tests subsection. It is intended for coders, billing staff, and clinicians who need a clearer understanding of the general categories of testing, the service elements discussed, and the reporting context covered by the AMA and RUC material.
Why This Topic Matters
Accurate understanding of autonomic function testing reporting helps support consistent coding and documentation for these specialized physiologic tests.
Article Sections
-
Autonomic Function Tests
Introduces the relevant CPT code group and the overall purpose of the article. It frames the testing categories addressed in the remainder of the guidance.
-
Autonomic Nervous System
Summarizes the physiologic background of the autonomic nervous system and the general function areas involved in testing. This section provides context for the testing categories discussed later.
-
Coding Tip
Presents a coding note related to one of the autonomic testing categories. The guidance is limited to reporting considerations discussed by the article.
-
Coding Tip
Provides a separate reporting note for another autonomic testing category. It highlights a procedural requirement discussed in the article.
-
Coding Tip
Offers additional reporting guidance for another test category and its required testing elements. This section continues the article’s coding-focused clarification.
-
Coding Tip
Explains a reporting note tied to the combined-function testing categories. It addresses how the article differentiates related test approaches.
-
Tilt Table Testing
Describes tilt table testing as a general method used in autonomic evaluation and places it in historical and clinical context. The section explains the broader testing approach without focusing on specific case details.
-
Coding Tip
Gives a brief note about when to use the alternate reporting approach discussed in the article. It reinforces the article’s broader guidance on test selection.
-
Terms Related to Autonomic Function Testing
Defines key terminology used in the descriptor language for autonomic testing. The section supports understanding of the testing concepts and related physiologic measurements.
-
Clinical Example (95921) / Description of Procedure (95921)
Provides a representative clinical scenario and a procedure narrative for one autonomic testing category. The example illustrates the type of case context discussed in the article.
-
Clinical Example (95922) / Description of Procedure (95922)
Provides a representative clinical scenario and a procedure narrative for another autonomic testing category. The example shows how the article ties testing concepts to clinical use.
-
Clinical Example (95923) / Description of Procedure (95923)
Provides a representative clinical scenario and a procedure narrative for sudomotor testing. The section expands on the testing context covered in the article.
-
Clinical Example (95924) / Description of Procedure (95924)
Provides a representative clinical scenario and a procedure narrative for combined autonomic testing. The section reflects the article’s discussion of multiple related test components.
-
Clinical Example (95943) / Description of Procedure (95943)
Provides a representative clinical scenario and a procedure narrative for the simultaneous quantitative testing approach. The section completes the article’s set of example-based explanations.
