CPT® Code 93660

Evaluation of cardiovascular function with tilt table evaluation, with continuous ECG monitoring and intermittent blood pressure monitoring, with or without pharmacological intervention

The procedure described by CPT® Code 93660 involves the evaluation of cardiovascular function through a tilt table test, which is a diagnostic tool used primarily to investigate the causes of syncope, commonly known as fainting. This test is essential for understanding how the cardiovascular system responds to changes in posture, particularly when a patient transitions from a supine (lying down) position to an upright position. During the procedure, continuous electrocardiogram (ECG) monitoring is employed to track the heart's electrical activity, while intermittent blood pressure monitoring is utilized to assess the patient's blood pressure at various intervals. The tilt table itself is equipped with restraints to ensure the patient remains securely in place as the table is tilted. Initially, the patient is positioned supine, and once the ECG electrodes and blood pressure monitor are in place, the table is tilted to a 60-degree angle. This angle is maintained to observe the patient's cardiovascular response, including heart rate and blood pressure changes, as well as any episodes of syncope. If the initial tilt does not induce syncope, a pharmacological intervention may be administered intravenously to provoke a response, after which the test is repeated. The entire process is carefully monitored to document any significant changes in heart rate, blood pressure, or the occurrence of syncope, providing valuable insights into the patient's cardiovascular health.
