What 95921 covers
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.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

95921 billing questions
When should 95921 be selected instead of 95922?
Use 95921 for testing of parasympathetic function, such as heart-rate responses to deep breathing or Valsalva. Code 95922 addresses vasomotor adrenergic function.
How does 95921 differ from 95924?
Code 95921 represents parasympathetic testing. Code 95924 is for combined parasympathetic and sympathetic adrenergic testing that includes tilt testing.
Can the professional and technical portions be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service with equipment and staff. Without either modifier, the claim represents the global service.
What documentation supports reporting 95921?
Document the clinical reason for testing, the parasympathetic maneuvers performed, the recorded responses, and the interpretation. The record should make clear that the service evaluated parasympathetic function.
Is 95923 another code for parasympathetic testing?
No. Code 95923 is for sudomotor autonomic testing, which assesses sweat-related function; 95921 evaluates parasympathetic function.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
