Viz HCM
End-to-end approach for detecting and directing hypertrophic cardiomyopathy (HCM) patients.
Increasing awareness and reach for a potentially fatal, yet commonly missed disease


Potentially fatal, yet commonly missed disease
1 Million people in the US suffer from hypertrophic cardiomyopathy (HCM). Only 20% of those have been diagnosed, with 5 years to diagnosis.
HCM is a leading cause of sudden cardiac death in people under age 35, but if detected early and treated, patients can achieve high quality of life and normal longevity.
End-to-end approach for detecting suspected HCM and directing patients
Viz HCM analyzes all 12-lead ECGs throughout the health system to flag and triage suspected cases to HCM specialists for diagnostic workup, all from the mobile app.
Flag suspected HCM: Review patients identified by AI as having signals of HCM
Follow Up: Direct patients to the HCM specialist for additional workup
Accelerate Diagnosis: View echo images and reports to diagnose HCM

Category III CPT® Codes for Assistive Algorithmic Electrocardiogram for Cardiac Dysfunction
Diagnosis, Therapeutics & Enhanced Pathways
Category III CPT codes support the adoption and potential reimbursement of emerging technologies. Effective January 1, 2025, codes +0764T and 0765T are included in the Hospital Outpatient Prospective Payment and Ambulatory Surgical Center Payment Systems - marking a key step forward for ECG-AI in clinical care.
CPT: +0764T
Description: Assistive algorithmic electrocardiogram risk-based assessment for cardiac dysfunction (eg, low-ejection fraction, pulmonary hypertension, hypertrophic cardiomyopathy); related to concurrently performed electrocardiogram
CPT: 0765T
Description: Assistive algorithmic electrocardiogram risk-based assessment for cardiac dysfunction (eg, low-ejection fraction, pulmonary hypertension, hypertrophic cardiomyopathy); related to previously performed electrocardiogram
