Autonomic nervous system testing
About 95923: Sudomotor autonomic function testing
Reports sudomotor autonomic testing, such as QSART or thermoregulatory sweat testing, to evaluate sweat-gland responses in suspected autonomic dysfunction.
Code 95923 represents testing of sweat-gland responses as an indicator of autonomic nerve function. The service may use QSART, a silastic sweat imprint, thermoregulatory sweat testing, or more than one of these approaches, with interpretation and a report. Neurologists and other clinicians who evaluate autonomic disorders commonly order it for problems such as suspected autonomic or small-fiber neuropathy, abnormal sweating, or related sensory and autonomic symptoms. Testing is generally performed in an autonomic or neurodiagnostic laboratory.
Choose 95923 when the function being evaluated is sudomotor, rather than parasympathetic or adrenergic function. Documentation should identify the clinical reason for testing, the method or methods performed, relevant results, and the interpretation. The service includes the interpretation and report. CMS recognizes a professional component billed with modifier 26 for interpretation and a technical component billed with modifier TC for equipment and staff; billing without either modifier represents the global service.

95923 billing questions
When should 95923 be selected instead of 95921 or 95922?
Use 95923 for sudomotor function, assessed through sweat responses. Codes 95921 and 95922 address parasympathetic and adrenergic function, respectively.
Does 95923 include interpretation and reporting?
Yes. The service includes interpretation and a report; CMS also permits separate professional and technical component billing with modifiers 26 and TC.
What do modifiers 26 and TC represent for this code?
Modifier 26 identifies the professional interpretation component, while TC identifies the technical work involving equipment and staff. Without either modifier, the claim represents the global service.
Can more than one sudomotor method be part of 95923?
Yes. The service may include one or more methods such as QSART, silastic sweat imprint, and thermoregulatory sweat testing.
What documentation supports 95923?
Record the reason for testing, the sudomotor method or methods performed, the findings, and the interpretation linking the results to the clinical question.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
