Summary & Overview
HCPCS S3902: Ballistocardiogram, Cardiac Diagnostic Monitoring
HCPCS Level II code S3902 represents a ballistocardiogram, a noninvasive diagnostic procedure that records the mechanical forces of cardiac contraction. Nationally, this code matters for policy and payment because it identifies a specialized cardiac monitoring service distinct from electrocardiography and other physiologic studies, and it can affect coverage, billing workflows, and reimbursement for ambulatory diagnostic and hospital outpatient providers.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what S3902 covers, the clinical context for ballistocardiography, and the typical sites where it is performed. The publication outlines which payers are included in benchmarking and policy comparisons and summarizes common billing considerations tied to this service.
This article provides benchmarks where available, summarizes relevant policy updates impacting reimbursement and coverage, and situates the procedure within clinical workflows for cardiac diagnostic monitoring. Data not available in the input is noted where applicable; the focus is on national implications for coding, billing, and clinical placement of the service.
Billing Code Overview
HCPCS Level II code S3902 describes a Ballistocardiogram, a noninvasive diagnostic procedure that records the mechanical forces generated by cardiac contraction. The service type is diagnostic cardiac monitoring focused on capturing cardiomechanical signals related to cardiac function. The typical site of service for this procedure is an ambulatory diagnostic facility or hospital outpatient setting, where specialized equipment and monitoring personnel are available.

Clinical & Coding Specifications
Clinical Context
A 68-year-old male with symptomatic orthostatic lightheadedness and unexplained palpitations is referred by his cardiologist for a Ballistocardiogram. The patient presents to an outpatient cardiology diagnostic lab where a trained technician places noninvasive sensors on a bed or chair to record the mechanical forces transmitted through the body from cardiac ejection. The typical workflow includes patient intake and consent, vital signs and rhythm strip screening, sensor placement and calibration, a resting supine or seated recording period (often 10–30 minutes), brief physiologic maneuvers if indicated (quiet breathing, Valsalva, positional change), and immediate data transfer to the interpreting cardiologist. The cardiologist reviews waveform morphology, timing of mechanical events relative to ECG if recorded, and integrates findings with clinical history and other cardiac testing (ECG, echocardiography) to assess cardiac output surrogates, ventricular contractility patterns, and potential conduction or mechanical abnormalities. Results are documented in the medical record and conveyed to the referring provider for management decisions.
