CPT Code 75571: Cardiac CT for Calcium Scoring, Without Contrast Material

CPT Code 75571 is used for cardiac computed tomography (CT) performed without contrast material, primarily to detect and score coronary artery calcium. This test focuses on visualizing calcified plaque in the coronary arteries, helping assess a patient's risk for heart disease of native coronary arteries. Unlike a full cardiovascular function study, it does not evaluate LV cardiac function, aortic valve anatomy, or soft tissue details within the cardiac structure, but instead provides a quantitative assessment of calcification.

Reimbursement for CPT Code 75571 may vary and is not typically covered by Medicare unless specific screening protocols or risk factors are documented. To support billing, providers should ensure accurate coding information, include a clinical indication for the scan (e.g., family history of heart disease of native vessels), and clearly note the calcium scoring methodology in the radiology report. Accurate coding helps optimize the revenue cycle and avoid claim denials.

Yes, CPT Code 75571 can be useful for patients with a history of aortocoronary bypass graft, bundle branch block, or other cardiac conditions, especially when evaluating long-term risks of further plaque development. However, it is important to note that this code does not assess electrical conduction or blood flow but rather provides insight into the structural buildup of calcium. It complements other tests aimed at evaluating cardiac structure and function.
