Abnormal Calcium Score
Understand Abnormal Calcium Score (CAC), also known as Coronary Artery Calcification or Coronary Calcium Score. This page provides information on CAC scoring, its role in assessing coronary artery disease risk, and relevant clinical documentation and medical coding considerations for healthcare professionals. Learn about the importance of accurate calcium scoring interpretation and its implications for patient care.
Measure of calcium buildup in heart arteries, indicating plaque and potential heart disease risk.
Usually asymptomatic, but may have symptoms of heart disease like chest pain or shortness of breath.
Cardiology clinics, radiology departments, or preventative health screenings.

When to use each related code
| Description | When to use |
|---|---|
| Calcium buildup in heart arteries. | Use for presence of coronary artery calcification detected on CT. |
| Narrowing of heart arteries. | Code when coronary stenosis or atherosclerosis is documented. Consider severity. |
| Chest pain due to reduced blood flow to the heart. | Use for angina symptoms and diagnosis confirmed by clinical findings. Specify type (stable, unstable). |
Best-practice checklist
- ✓Document CAC score quantification (Agatston).
- ✓Specify CAC scan type (e.g., non-contrast CT).
- ✓Note coronary artery location of calcification.
- ✓Correlate CAC score with risk factors (age, smoking).
- ✓Link CAC findings to atherosclerosis diagnosis/severity.
Common pitfalls to avoid
Using incorrect CPT or ICD-10 codes for coronary artery calcification, leading to claim denials.
Insufficient documentation of CAC results, impacting accurate coding and reimbursement.
Lack of clear medical necessity for CAC testing, increasing audit risk and potential recoupment.
Best-practice tips
- 01Document CAC risk factors: age, smoking, hypertension, diabetes.
- 02Code CAC score accurately using CPT 71110 ICD-10 Z95.820.
- 03For zero CAC score, document "absence of CAC" for clarity.
- 04Correlate CAC score with clinical findings for accurate risk stratification.
- 05Ensure medical necessity for CAC testing per payer guidelines.
Step-by-step checklist
- 1
Verify patient age and risk factors for CAD.
- 2
Check for prior CT scans to avoid redundancy.
- 3
Confirm no contraindications to non-contrast CT.
- 4
Ensure proper patient preparation and positioning.
- 5
Document CAC score, interpretation, and plan.
Ready-to-paste narrative
Patient presents for cardiovascular risk assessment due to family history of coronary artery disease. The patient is asymptomatic with no current complaints of chest pain, shortness of breath, or palpitations. A coronary artery calcium scan (CAC), also known as a coronary calcium score or abnormal calcium score, was ordered to assess for subclinical atherosclerosis. The Agatston score was determined to be [Insert Score]. This result indicates [Interpretation of Score: e.g., mild, moderate, severe, or no coronary artery calcification]. This finding has been documented in the patient's electronic health record (EHR) and will be used to guide further management decisions. Patient counseling regarding the significance of the coronary artery calcification score and its implications for cardiovascular risk was provided. Lifestyle modifications including diet, exercise, and smoking cessation were discussed. The patient's risk factors, including hypertension, hyperlipidemia, diabetes, and family history, were reviewed. Follow-up appointments were scheduled for further cardiovascular risk stratification and management according to current clinical guidelines. ICD-10 code [Insert appropriate ICD-10 code, e.g., R93.6 for abnormal findings on diagnostic imaging of heart] and CPT code [Insert appropriate CPT code, e.g., 71110 for cardiac CT calcium scoring] were used for billing and coding purposes.
Common questions and answers
How does an abnormal calcium score impact coronary artery disease risk stratification in asymptomatic patients?+
An abnormal calcium score, particularly a score above zero, signifies the presence of coronary artery calcification and is a strong independent predictor of future cardiovascular events, even in asymptomatic patients. While a zero calcium score indicates a low risk of coronary artery disease events in the near term, a higher score reflects a greater atherosclerotic burden and corresponds to a progressively elevated risk. This information allows for more precise risk stratification beyond traditional factors and facilitates personalized preventive strategies. For example, patients with high calcium scores may benefit from more aggressive risk factor modification, including lifestyle changes and pharmacotherapy. Consider implementing calcium scoring into your risk assessment workflow for asymptomatic patients to improve cardiovascular risk prediction and guide treatment decisions.

What are the best practices for interpreting and communicating coronary artery calcification (CAC) scores with patients to improve adherence to preventive measures?+
Effectively communicating CAC score results to patients requires clear, non-alarmist language and personalized context. Explain that a CAC score reflects the amount of calcified plaque in the coronary arteries and serves as an indicator of future cardiovascular risk, not an immediate threat. Emphasize that even with a high CAC score, lifestyle modifications and other preventive measures can significantly reduce their risk of future heart attack or stroke. Connect the CAC score to their individual risk factors, and provide specific recommendations for lifestyle changes, such as diet, exercise, and smoking cessation. If indicated, discuss the potential benefits of pharmacotherapy like statins or aspirin. Patients are often more motivated to adhere to preventive measures when they understand their personal risk and the potential impact of lifestyle choices. Learn more about effective patient communication strategies for CAC scores and explore resources to aid in shared decision-making.
When should coronary artery calcium scoring be considered in the primary prevention setting, and what are the potential limitations of its use?+
Coronary artery calcium scoring is generally recommended for asymptomatic adults at intermediate risk of coronary artery disease, particularly those whose risk is unclear based on traditional risk factors alone. It can be particularly valuable in patients with a family history of premature heart disease or those considering initiating statin therapy. However, it is not universally recommended for all patients. CAC scoring has limitations, including its inability to assess non-calcified plaque or stenosis severity. It's also not appropriate for individuals at very low or very high risk based on clinical factors. The decision to order a CAC scan should be made on a case-by-case basis through shared decision-making with the patient, considering their individual risk profile, preferences, and the potential impact of the results on management. Explore how shared decision-making tools can help incorporate patient preferences and values into the discussion about CAC scoring.
