CPT CODE AND ICD9
Suggested CPT Codes:
ANS Testing
CPT Coding 95921
The requirement is that at least two of the tests should be performed in order for code 95921 to
apply:
95921 = Testing of autonomic nervous system function; cardiovagal innervations (parasympathetic
function) Procedure = including the following: Valsalva ratio, and 30:15 ratio
Sudomotor function CPT Code
CPT Coding 95923:—The appropriate code for galvanic skin response is 95923 (Testing of
autonomic nervous system function; sudomotor, including one or more of the following: quantitative
sudomotor axon reflex test [QSART], silastic sweat imprint, thermoregulatory sweat test, and
changes in sympathetic skin potential).Only a single unit of 95923 regardless of the number of limbs
the doctor tests should be Bill.
ANS New Coding 2013 *
ANS CPT code without the use of a tilt Table
Code 95943 has been established to report when an autonomic function testing does not include
beat–to–beat recording, or for testing without the use of a tilt table. This is a simpler, automated
procedure compared to the other autonomic codes. Simultaneous, independent, quantitative
measures of both parasympathetic function and sympathetic function, based on time–frequency
analysis of heart rate variability concurrent with time–frequency analysis of continuous respiratory
activity, with mean heart rate and blood pressure measures, during rest, paced (deep) breathing,
Valsalva maneuvers, and head–up postural change.
*Do not report 95943 in conjunction with 93040, 95921, 95922, and 95924
