Frequently asked questions

How much does an echocardiogram cost without insurance?

A transthoracic echocardiogram typically costs $200 to $500 on a cash-pay basis. This is significantly less than hospital-based pricing, which can run $1,500 to $3,000 before insurance adjustments. A stress echocardiogram (echo with treadmill exercise) costs $400 to $800. Cash-pay pricing on OpenDoc provides the same diagnostic quality at transparent, predictable pricing.

What is the difference between a cardiologist and an electrophysiologist?

A general cardiologist diagnoses and treats the full spectrum of heart disease. An electrophysiologist (EP) is a cardiologist with 1-2 years of additional fellowship training specifically in the heart's electrical system. See an EP for arrhythmias (atrial fibrillation, SVT, ventricular tachycardia), if you need a pacemaker or defibrillator, or for catheter ablation procedures.

How much does a stress test cost without insurance?

A standard treadmill stress test costs $200 to $500 cash-pay. A nuclear stress test, which uses radioactive tracers for more detailed imaging, costs $500 to $1,200. A stress echocardiogram falls in between at $400 to $800. Your cardiologist will recommend the appropriate type based on your symptoms, risk factors, and ability to exercise.

Do I need a referral to see a cardiologist?

No referral is needed on OpenDoc. You can search directly for a general cardiologist or any cardiac subspecialist. If you are experiencing chest pain, palpitations, shortness of breath, or have risk factors like family history of heart disease, you should not delay evaluation waiting for a referral.

What is a coronary calcium score and is it worth getting?

A coronary calcium score is a low-dose CT scan that measures calcium deposits in your coronary arteries, indicating plaque buildup. It costs only $75 to $200 cash-pay and takes about 15 minutes with no preparation needed. It is one of the best screening tools for asymptomatic coronary artery disease and is recommended for adults aged 40-75 with intermediate cardiovascular risk.

How much does a Holter monitor cost without insurance?

A 24-hour Holter monitor costs $150 to $350 cash-pay, including the device, wearing period, and interpretation by a cardiologist. Extended monitors (7 to 30 days) cost $200 to $500. These monitors continuously record your heart rhythm to catch intermittent arrhythmias that a standard EKG might miss.

What is the difference between interventional cardiology and cardiac surgery?

Interventional cardiologists perform minimally invasive catheter-based procedures through small punctures in the wrist or groin — including stenting, angioplasty, and some valve procedures (TAVR). Cardiac surgeons perform open-heart surgery including coronary artery bypass grafting (CABG) and surgical valve replacement. Many conditions that previously required open surgery can now be treated interventionally.

Should I see a cardiologist for high blood pressure?

Most hypertension is managed by primary care physicians. You should see a cardiologist if your blood pressure is resistant to 3 or more medications, you have signs of end-organ damage (heart enlargement, kidney dysfunction), you are under 30 with new hypertension (suggesting secondary causes), or you have hypertension with other cardiac symptoms like chest pain or shortness of breath.
