CPT 75571: Non-Contrast CT Coronary Calcium Scoring

CPT code 75571 denotes a non-contrast computed tomography (CT) examination performed to quantitatively measure coronary artery calcium. Coronary calcium scoring is a widely used risk-stratification tool for atherosclerotic cardiovascular disease that provides an objective measure of calcified plaque burden and helps guide preventive care decisions. Nationally, the availability and coverage of calcium scoring affect access to preventive cardiology services and influence imaging utilization patterns.

Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication reviews coverage nuances and common billing practices across these major payers, highlights typical sites of service (outpatient imaging centers and hospital outpatient departments), and summarizes clinical context around coronary artery calcium scoring.

Readers will find concise benchmarks for how CPT code 75571 is used, an overview of policy considerations that influence access and reimbursement, and clinical context explaining when non-contrast coronary CT calcium scoring is performed and reported. Data not available in the input is noted where applicable.

Billing Code Overview

CPT code 75571 describes a non-contrast cardiac computed tomography (CT) scan for quantitative measurement of coronary artery calcium (coronary calcium scoring). The procedure uses CT imaging without intravenous contrast to quantify calcified plaque in the coronary vessels and produce an Agatston or equivalent calcium score.

Service type: Diagnostic imaging, non-contrast CT for coronary artery calcium scoring
Typical site of service: Imaging center or hospital outpatient radiology/CT suite

Clinical & Coding Specifications

Clinical Context

A 58-year-old patient with multiple cardiovascular risk factors (hypertension, hyperlipidemia, family history of premature coronary artery disease) is referred by their primary care physician for coronary artery calcium (CAC) scoring to quantify coronary atherosclerotic burden. The patient arrives at an outpatient radiology clinic or hospital imaging center and is registered for a non-contrast cardiac CT. The CT technologist confirms identity, reviews contraindications (allergies and recent contrast), and positions the patient supine with ECG leads applied for cardiac gating as needed. The imager (radiologist or cardiology imaging specialist) reviews prior imaging and indications, performs acquisition using a non-contrast, ECG-gated protocol for coronary calcium scoring, and generates an Agatston score with region-of-interest measurements for coronary vessels. Results are interpreted and a structured report is issued with the Agatston score, vessel-specific scores, and an assessment of cardiovascular risk. The ordering clinician receives the report and integrates the score with clinical risk factors to guide preventive therapy planning and risk communication. Typical sites of service include outpatient radiology centers, hospital outpatient departments, and cardiology clinics with CT capability. The service type is diagnostic, non-contrast cardiac CT for quantitative coronary calcium measurement, performed without intravenous contrast.

Modifier	Description	When to Use
`26`	Professional component	When reporting only the interpreting physician's work separate from technical component billing.
`TC`	Technical component	When reporting only facility/technical resources (scanner, technologist) separate from professional interpretation.
`59`	Distinct procedural service	When another separately identifiable service was performed the same day and not usually reported together; use to indicate distinct non-overlapping procedures.
`76`	Repeat procedure by same physician	When the same service is repeated by the same provider on the same day (note: `76` not in provided list; use `77` instead).
`77`	Repeat procedure by another physician/other practitioner	When the exact procedure is repeated by a different provider the same day.
`52`	Reduced services	When a limited or reduced version of the procedure is performed (e.g., incomplete study due to patient inability to cooperate).
`53`	Discontinued procedure	When the procedure is started but discontinued due to patient factors or peri-procedural events.
`26`	Professional component	When the interpreting physician bills separately from the facility (duplicate of above entry retained for emphasis).
`62`	Two surgeons	Rarely applicable; used when two surgeons work together — typically not used for CT but included for complex multidisciplinary procedures.
