Coronary calcium scans are available at most hospital radiology departments and many freestanding imaging centers. The scan is quick, widely accessible, and often surprisingly affordable, with some facilities charging as little as $49 out of pocket. Finding a location near you usually takes a phone call to your local hospital’s imaging department or a quick search on their website.
Types of Facilities That Offer the Scan
Hospital-based imaging centers are the most common places to get a coronary calcium scan. Major health systems like Johns Hopkins, Cleveland Clinic, and many regional hospitals offer the test at multiple satellite locations, not just their main campus. Johns Hopkins, for example, performs calcium scoring at five locations across Maryland, from Bethesda to White Marsh. Your local hospital system likely has a similar setup.
Freestanding outpatient imaging centers also offer the scan, and these are sometimes the more affordable option. These independent facilities typically have the same CT equipment as hospitals but lower overhead costs. Some hospitals even run dedicated “heart scan” programs with promotional pricing. Silver Cross Hospital in Illinois, for instance, offers a $49 heart scan at three locations.
The scan uses a standard high-speed CT scanner, which is available at virtually any modern imaging facility. An older technology called electron beam CT also works but is far less common today since newer multi-detector CT scanners are more versatile and equally accurate.
How to Find a Location Near You
Start with your nearest hospital system’s website. Most list “cardiac CT” or “calcium scoring” under their imaging services, and many now let you schedule directly through an online patient portal. You can also call the imaging department directly. If you have a primary care doctor, their office can point you to in-network facilities and provide a referral if needed.
Some facilities require a doctor’s order before scheduling, while others let you book on your own as a self-referred patient. Cleveland Clinic notes that patients sometimes get the test done independently and then bring the results to a provider. If you’re paying out of pocket, self-referral is more common. If you want insurance to cover any part of the cost, you’ll almost certainly need a physician’s order.
What the Scan Costs
Cash-pay prices for a coronary calcium scan typically range from $49 to $200, making it one of the more affordable cardiac tests available. Many hospitals advertise flat-rate pricing specifically for this scan because it’s fast, uses no contrast dye, and requires minimal staff time.
Insurance coverage is a different story. Medicare and most private insurers generally do not cover calcium scoring for people without symptoms. The Centers for Medicare and Medicaid Services considers cardiac CT reasonable and necessary for evaluating suspected symptomatic coronary artery disease, but a screening scan in someone who feels fine doesn’t meet that threshold. If you have symptoms like chest pain with an inconclusive stress test or an unreadable EKG, your doctor may be able to get the scan covered. For most people seeking a preventive screen, though, this is an out-of-pocket expense.
Who Should Consider Getting One
The scan is most useful for adults over 40 who fall into a gray zone of heart disease risk. Guidelines from the American College of Cardiology and American Heart Association recommend considering calcium scoring for people at intermediate risk (a 7.5% to 20% estimated chance of a cardiovascular event over 10 years) and even those at borderline risk (5% to 7.5%). Your doctor can calculate this number using your age, blood pressure, cholesterol, and smoking status.
Certain factors push the scan from “maybe useful” to “strongly worth considering.” These include a family history of early heart disease, persistently high LDL cholesterol (160 or above), high triglycerides (175 or above), chronic kidney disease, metabolic syndrome, and inflammatory conditions like rheumatoid arthritis or psoriasis. Women with a history of preeclampsia or premature menopause also fall into this category, as do people of South Asian descent, who carry higher baseline cardiovascular risk.
The scan is not recommended for people already diagnosed with heart disease, since the result won’t change their treatment. It’s also not particularly helpful for very low-risk individuals or very high-risk individuals whose management path is already clear.
What to Expect During the Scan
The entire visit takes about 10 to 15 minutes, with the actual CT scan lasting only a few minutes. You’ll lie on a table, have small electrodes placed on your chest to sync the images with your heartbeat, and hold your breath briefly while the scanner captures pictures of your coronary arteries. There’s no IV, no contrast dye, and no recovery time. You can drive yourself home and resume normal activities immediately.
Preparation is minimal. Avoid food, drinks, caffeine, and tobacco for four hours beforehand. You’ll remove any metal jewelry or glasses and change into a hospital gown. That’s it.
Radiation exposure is low. Modern scanners deliver about 1 millisievert on average, which is roughly equivalent to a mammogram or three to four months of natural background radiation you’d absorb just living your daily life.
Understanding Your Results
Results are reported as an Agatston score, a number that reflects how much calcified plaque is in your coronary arteries. The score falls into one of five stages, and each one carries a meaningfully different level of risk.
- Score of 0: No calcified plaque detected. This is the best possible result and generally means very low short-term risk. Lifestyle optimization is the main recommendation.
- Score of 1 to 99: Mild plaque buildup. Risk is elevated compared to a zero score, and your doctor will likely discuss cholesterol-lowering treatment along with lifestyle changes. Where your score falls relative to others your age and sex matters here.
- Score of 100 to 299: Moderate plaque. Both lifetime and short-term cardiovascular risk are meaningfully higher, and more aggressive cholesterol management is typically recommended.
- Score of 300 to 999: Severe plaque burden. The cardiovascular risk at this level is comparable to someone who has already had a heart attack. Intensive treatment is the standard approach.
- Score of 1,000 or higher: Extensive plaque. Risk is similar to someone who has had multiple cardiac events, and the most aggressive preventive therapies are warranted.
A score of zero is powerfully reassuring but doesn’t mean zero risk forever. It reflects a snapshot in time. For scores above zero, the number gives your doctor a concrete, personalized data point that generic risk calculators can’t provide. Many people find that the result, whether reassuring or alarming, gives them the clarity to either ease up on worry or commit to treatment they’d been on the fence about.
