In simple words: This test checks how well the part of your nervous system that controls things like blood pressure and heart rate is working. It involves lying on a tilt table and doing some breathing exercises to see how your body reacts.

This CPT code encompasses a comprehensive evaluation of both the parasympathetic and sympathetic branches of the autonomic nervous system.The assessment involves multiple components, mandating at least five minutes of passive tilt table testing to assess the adrenergic function.Additional testing for parasympathetic function must also be included.

Example 1: A patient presents with symptoms suggestive of autonomic dysfunction, including dizziness upon standing (orthostatic hypotension), and the physician orders this test to differentiate between neurogenic and non-neurogenic causes., A patient with a history of diabetes exhibits symptoms of autonomic neuropathy, and this test is conducted to assess the extent and nature of the autonomic involvement., A post-surgical patient experiences unexplained episodes of fainting, and this comprehensive autonomic testing helps rule out any post-operative autonomic dysregulation.

* Detailed patient history, including symptoms and relevant medical conditions.* Complete recording of the autonomic function tests (e.g., ECG, blood pressure monitoring, tilt table test results).* Physician's interpretation of the test results, including a detailed analysis of the parasympathetic and sympathetic responses.* Documentation of any medications the patient is taking that might affect autonomic function.

** This test requires specialized equipment and expertise, and the interpretation of results requires clinical judgment by a qualified healthcare professional. Accurate reporting requires adherence to CPT guidelines and payer-specific rules.
