What 95924 covers
This service evaluates both parasympathetic (cardiovagal) and sympathetic adrenergic responses during a tilt-table protocol. Testing can include continuous blood pressure and heart-rate monitoring during maneuvers such as Valsalva and deep breathing, along with the tilt response. Neurology or autonomic-disorders services commonly perform it for patients with findings such as unexplained syncope, orthostatic symptoms, or suspected autonomic neuropathy. A physician or qualified health professional interprets the physiologic responses.
Select this code when the performed protocol assesses both parasympathetic and sympathetic adrenergic function with tilt-table testing, rather than testing only one autonomic function or a different modality. The record should identify the maneuvers performed, monitoring and measurements obtained, and interpretation of the responses. CMS recognizes professional and technical components: report modifier 26 for interpretation, modifier TC for equipment and staff, or no modifier when billing the global service.

How to choose
- 95921Autonomic testingParasympathetic function
- 95921 addresses parasympathetic cardiovagal function; 95924 is for combined parasympathetic and sympathetic adrenergic assessment with tilt-table testing.
- 95922Autonomic testingAdrenergic function
- 95922 addresses sympathetic adrenergic function alone; 95924 represents a combined autonomic assessment that includes tilt-table testing.
- 95923Sweat function testSudomotor testing
- 95923 is used for sudomotor assessment, such as testing sweat-related autonomic function. It is not the combined tilt-table cardiovagal and adrenergic service.
- 95919PupillometryOne or both pupils
- 95919 is quantitative pupillometry. It evaluates pupillary responses rather than the combined tilt-table autonomic responses reported with 95924.
95924 billing questions
When should 95924 be selected instead of 95921 or 95922?

Can 95921 or 95922 also be reported for the same testing?
Choose 95924 when the combined tilt-table protocol is performed. The record should make clear which distinct testing services were performed before reporting additional autonomic testing codes.
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.
