, an artificial intelligence (AI)-powered medical technology company focused on transforming ECGs/EKGs to save lives through earlier detection of heart disease, today announced that the Centers for Medicare & Medicaid Services (CMS) has included AI-ECG technology in the 2025 Hospital Outpatient Prospective Payment System (OPPS) final rule under assignment APC 5734. This approval would allow outpatient settings to receive reimbursement for HeartSciences’ MyoVista® wavECGTM algorithm and MyoVista® InsightsTM low ejection fraction algorithm, upon FDA clearance. The payment rate is expected to be $125.

Andrew Simpson, CEO of HeartSciences, said, “The inclusion of AI-ECG for reimbursement by CMS represents a significant milestone for commercialization of our products and further validates the enormous market opportunity, particularly given the widespread use of the ECG in clinical practice. We look forward to submitting to the FDA and bringing to market both our MyoVista wavECG and MyoVista Insights platform in 2025.”
