Autonomic testing
About 95921: Parasympathetic autonomic function testing
Reports autonomic testing of parasympathetic function, such as heart-rate responses to deep breathing or a Valsalva maneuver, during evaluation of autonomic symptoms.
This service assesses parasympathetic control of heart rate, commonly by recording the heart-rate response to deep breathing or a Valsalva maneuver. Neurologists and clinicians specializing in autonomic disorders may order it when evaluating suspected autonomic neuropathy or symptoms such as unexplained lightheadedness or fainting. Testing is generally performed in an autonomic or neurophysiology laboratory with ECG monitoring and trained staff.
Report 95921 when the documented service evaluates parasympathetic function; the record should identify the tests performed, the clinical indication, recorded findings, and the interpreting clinician’s conclusions. It may be billed globally when one provider or entity supplies both the testing resources and interpretation. Modifier 26 identifies the professional interpretation, while modifier TC identifies the technical service, including equipment and staff. CMS separately prices these component claims.
CMS billing rules for 95921
