Billing code 95924: Autonomic testingMedicare rate & RVUs

Medicare pays $154.65 for 95924 nationally in the office. Local office rates run $139.84–$200.79.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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 testing

95921 addresses parasympathetic cardiovagal function; 95924 is for combined parasympathetic and sympathetic adrenergic assessment with tilt-table testing.

95922Autonomic testing

95922 addresses sympathetic adrenergic function alone; 95924 represents a combined autonomic assessment that includes tilt-table testing.

95923Sweat function test

95923 is used for sudomotor assessment, such as testing sweat-related autonomic function. It is not the combined tilt-table cardiovagal and adrenergic service.

95919Pupillometry

95919 is quantitative pupillometry. It evaluates pupillary responses rather than the combined tilt-table autonomic responses reported with 95924.

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.
