CMS Establishes New National Billing Code for AI-Driven Coronary Artery Calcium and Aortic Valve Calcium Analysis on Chest CT Scans

16 April 2026

Bunkerhill Health, a pioneering agentic AI company focused on transforming healthcare operations, has achieved a significant milestone with the Centers for Medicare and Medicaid Services (CMS) establishing a dedicated national billing code and payment mechanism under the Hospital Outpatient Prospective Payment System (OPPS). This code specifically targets algorithmic analysis of coronary artery calcium (CAC) and aortic valve calcium (AVC) derived from standard chest CT scans, effective from April 1, 2026. This development is poised to revolutionize diagnostics and imaging in American hospitals by enabling seamless reimbursement for AI-enhanced cardiac risk assessments.

The new OPPS code addresses a critical gap in hospital reimbursement frameworks, allowing facilities to bill for advanced AI processing of routinely performed chest CTs. Chest CT scans are ubiquitous in emergency departments, oncology staging, and routine screenings, yet their potential for opportunistic cardiac screening has remained underutilized due to prior reimbursement hurdles. Bunkerhill's AI platform automates the detection and quantification of CAC and AVC scores, providing instant, actionable insights into patients' cardiovascular risk profiles without additional radiation exposure or workflow disruptions. This integration aligns perfectly with hospital priorities in cardiology and critical care, where early identification of atherosclerosis and valvular disease can significantly improve patient outcomes and reduce long-term costs.

For hospital administrators and clinical leadership, this CMS decision represents a strategic opportunity to deploy cutting-edge healthcare information technology that enhances diagnostic efficiency. Bunkerhill Health also secured U.S. Food and Drug Administration (FDA) clearance for its solution, underscoring its clinical validity and safety. The AI model has demonstrated high accuracy in validating CAC and AVC measurements against gold-standard references, making it a reliable tool for radiologists and cardiologists. Hospitals can now incorporate this into their radiology and patient monitoring protocols, potentially qualifying for value-based care incentives under Medicare programs.

From a business perspective, this billing code facilitates broader adoption across U.S. healthcare systems, particularly in facilities management and procurement of AI tools. Procurement professionals can justify investments in Bunkerhill's platform through direct OPPS reimbursements, estimated to cover a substantial portion of implementation costs. This move supports digital transformation initiatives, enabling hospitals to extract maximum value from existing imaging infrastructure. Strategic partnerships between AI vendors like Bunkerhill and hospital networks are likely to accelerate, fostering innovations in healthcare management and predictive analytics.

Regulatory experts note that CMS's proactive stance on AI reimbursement signals a maturing ecosystem for algorithmic diagnostics. This code not only validates AI's role in emergency care and preventive cardiology but also sets precedents for future approvals in areas like oncology and orthopaedics imaging analysis. Hospital executives should monitor upcoming CMS guidance on documentation and quality reporting tied to this code to optimize revenue cycles. Bunkerhill's announcement highlights the intersection of policy, technology, and clinical needs, positioning U.S. hospitals at the forefront of AI-driven precision medicine.

Looking ahead, this development could spur investments in complementary technologies, such as integrated PACS systems and telemedicine platforms that leverage CAC/AVC data for remote consultations. For medical technology vendors, it underscores the importance of FDA clearance paired with payer alignment. Clinical leaders in nephrology and urology may explore similar AI applications for incidental findings on CTs. Overall, this CMS code empowers hospitals to advance their infection control and operational resilience by prioritizing non-invasive, high-impact diagnostics amid evolving healthcare demands.

In summary, Bunkerhill Health's breakthrough exemplifies how targeted regulatory changes can drive facilities management upgrades and service provider collaborations, ensuring American hospitals remain competitive in a rapidly digitizing landscape. This story continues to unfold with potential expansions into respiratory care and surgical planning applications.
