Billing code 75571: Calcium scoringMedicare rate & RVUs in Minnesota
Noncontrast cardiac CT with quantitative coronary calcium assessment, reported when a clinician needs a measure of calcified coronary atherosclerotic burden.
Medicare pays $100.64 for 75571 in the office in Minnesota (Minnesota). Which amount applies depends on the service address.
Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 75571 covers
This service uses a noncontrast CT scan of the heart to quantify calcified plaque in the coronary arteries. It is commonly ordered as part of cardiovascular risk assessment; the resulting calcium score measures calcified burden rather than showing the coronary artery lumen as a contrast angiogram would. A radiologic technologist acquires the images, and a radiologist or cardiologist typically interprets them and documents the quantitative findings.
Report 75571 when the study includes both the noncontrast cardiac CT and quantitative coronary calcium evaluation. Documentation should support the scan performed, the quantified result, and the interpreting clinician’s findings. The service may be billed globally, or the interpretation and image acquisition may be billed separately with modifier 26 or TC, respectively. When multiple diagnostic imaging procedures are reported, the CMS multiple-procedure reduction applies to both the technical and professional components.

How to choose
- 75572Cardiac CT
- 75571 quantifies coronary calcium on noncontrast images; 75572 evaluates cardiac structure and morphology with CT.
- 75574Coronary CTA
- 75571 assesses calcified coronary burden without contrast. 75574 is coronary CT angiography, which uses contrast to evaluate the coronary arteries.
- 75577Coronary plaque analysis
- 75571 is noncontrast coronary calcium scoring. 75577 is a separate quantitative and qualitative plaque assessment, not the calcium-score service.
75571 billing questions
How does 75571 differ from a coronary CT angiogram?
75571 quantifies coronary calcium on a noncontrast cardiac CT. A coronary CT angiogram, such as 75574, uses contrast to evaluate the coronary arteries.
Can the interpretation and scan acquisition be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Billing without either modifier represents the global service.
Does the multiple-procedure reduction affect only the technical component?
No. CMS applies the diagnostic imaging multiple-procedure reduction to both the technical and professional components.
What documentation supports reporting 75571?
The record should identify the noncontrast cardiac CT, the quantitative coronary calcium findings, and the interpreting clinician’s report.
Is 75571 the right code when the CT evaluates cardiac structure?
Use 75571 for quantitative coronary calcium assessment. Cardiac CT performed to evaluate structure and morphology is represented by a different service, such as 75572.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
