Summary & Overview
CPT 93660: Tilt-Table Test for Reflex-Mediated Syncope Evaluation
CPT code 93660 denotes the tilt-table test, a diagnostic cardiovascular procedure used to evaluate reflex mediated syncope by monitoring heart rate and blood pressure while changing the patient’s position. Nationally, this code is important for hospitals and cardiology practices that diagnose unexplained fainting, as it captures an office-based or outpatient service that can guide further management and specialty referral.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical purpose of the test, typical sites of service, and common billing considerations associated with CPT code 93660.
This publication provides benchmarks and coverage context relevant to facilities and clinicians billing for tilt-table testing, summarizes typical clinical indications and workflow for the service, and highlights areas where policy updates or variation in coverage may affect utilization. Data not available in the input are clearly noted where applicable.
Billing Code Overview
CPT code 93660 describes a tilt-table test performed to evaluate causes of reflex mediated syncope. The procedure involves positioning the patient on a motorized tilt table while continuous cardiac and blood pressure monitoring is performed. The clinician rotates the patient from supine to upright positions to provoke symptoms and may administer medication to increase heart rate and repeat portions of the test.
Service type: Diagnostic cardiovascular function testing
Typical site of service: Hospital outpatient department, specialized cardiology testing lab, or ambulatory surgical center
Clinical & Coding Specifications
Clinical Context
A typical patient is a 45-year-old adult referred to a cardiac electrophysiology laboratory for evaluation of recurrent unexplained syncope or presyncope after initial history, physical exam, orthostatic vitals, and ambulatory ECG monitoring fail to establish a cause. The patient arrives fasting, having withheld select medications per pre-procedure instructions. In the procedural workflow, nursing places continuous ECG leads and noninvasive blood pressure monitoring, and IV access is obtained. The patient is secured on a motorized tilt table and baseline supine monitoring is recorded. The table is tilted to incremental upright angles (typically to 60–70 degrees) for a monitored interval while the clinical team observes for reproduction of symptoms, ECG rhythm changes, and blood pressure responses. If needed and per protocol, pharmacologic provocation (for example, isoproterenol or sublingual nitroglycerin in some protocols) may be administered to increase heart rate and augment sensitivity of the test; monitoring continues and the table may be returned to supine. The attending cardiologist documents indications, hemodynamic responses, rhythm strips, medications given, and whether the test reproduces syncope or presyncope. Post-procedure, the patient is monitored until hemodynamically stable and given discharge instructions. Typical site of service is an outpatient cardiac catheterization/EP lab or hospital-based procedure area. Service type is diagnostic cardiac autonomic testing (tilt-table testing) with continuous hemodynamic monitoring.
