Do you believe current Medicare payment policies are hindering the quality of specialized cardiac care?

Between 2010 and 2026, inflation-adjusted Medicare payments for cardiac CT scans dropped between 27% and 68%. Despite these lower costs per service, overall real fee schedule spending rose by $22.0 million during this period.

Why it matters

The analysis highlights a divergence where surging diagnostic volume outpaced declining unit payments. This trend underscores how changes in fee structures interact with clinical utilization rates to shape total healthcare expenditures.

Researchers found that global payment for coronary CT angiography declined 68.3%, while technical component payments fell 74.8%. CCTA volume increased 408% between 2013 and 2024, yet the average real allowed charge per service fell 45.9%.

The players

Journal of Cardiovascular Computed Tomography

This is a peer-reviewed medical journal that publishes research related to cardiovascular imaging technologies and clinical applications.

Mayo Clinic

This is a prominent non-profit American academic medical center and health system based in Phoenix and other locations that focuses on integrated clinical practice and research.

The details

Researchers determined these figures by calculating national unadjusted non-facility payments for global, professional, and technical components. They identified that a $51.4 million volume effect was partially offset by unit revenue and interaction effects, resulting in the net increase in total spending.

2010-2026: The period during which Medicare payments for cardiac CT declined.
2011: The year that experienced the largest single-year payment reduction.
2013-2024: The period when CCTA volume rose by 408%.
2021: The year the AHA/ACC issued a Class 1 recommendation for CCTA.
September 30, 2026: The research was published in the Journal of Cardiovascular Computed Tomography.

The Big Picture

This trend follows the increased clinical adoption and utilization patterns established by the 2021 AHA/ACC guidelines Class 1 recommendation for CCTA. The data confirms how specific clinical practice standards drive diagnostic volume even as fee schedules remain under downward pressure.

These trends reflect shifting reimbursement structures that influence the availability and cost of cardiac imaging services. Patients may encounter varying out-of-pocket costs and facility options as providers navigate these long-term fee schedule adjustments.

The takeaway

The data illustrates that even as individual reimbursement rates for diagnostic procedures shrink, total healthcare costs can continue to rise through high utilization. Clinicians and patients should remain aware of how evolving payment policies shape the landscape of affordable cardiovascular care.
