Understanding Your Coverage Options
Original Medicare (Part B - Outpatient)

Medicare also covers a range of cardiac diagnostic tests including electrocardiograms (ECGs), echocardiograms, stress tests, nuclear stress tests, and cardiac catheterization.
Medicare Part B also covers several cardiovascular preventive services at no cost to you. These include cardiovascular disease screenings (cholesterol, lipid, and triglyceride tests) once every five years, and cardiovascular behavioral therapy - a once-per-year visit with your doctor to discuss aspirin use, blood pressure management, and diet.
For most outpatient cardiovascular services, you pay 20% coinsurance after your annual $283 Part B deductible (2026). Preventive services are covered at 100% with no deductible or coinsurance.

Medicare Advantage (Part C)
Covered - may offer additional cardiac benefitsMedicare Advantage plans must cover all cardiovascular services that Original Medicare covers. Some Medicare Advantage plans may also offer additional benefits for cardiovascular disease management, such as disease management programs, telehealth services, or transportation to cardiac appointments.
Cost-sharing under Medicare Advantage varies by plan. Some plans may have lower copays for specialist visits and cardiac tests. However, Medicare Advantage plans use provider networks, so verify that your cardiologist and preferred hospital are in-network before receiving care.
What It Covers
- All cardiovascular services covered by Original Medicare
- Additional cardiac disease management programs (varies by plan)
- Telehealth services for cardiac monitoring (varies by plan)
What It Doesn't Cover

Verify Your Cardiologist is In-network
Medicare Advantage plans use provider networks. Before scheduling a cardiology appointment, verify that your cardiologist and preferred hospital are in-network. Receiving care from an out-of-network provider can result in significantly higher costs.

✦ Key Rules for Cardiovascular Disease Coverage
Preventive Cardiovascular Services are Free
Medicare Part B covers cardiovascular disease screenings (cholesterol, lipid, and triglyceride tests) once every five years at no cost to you - no deductible or coinsurance. Medicare also covers cardiovascular behavioral therapy once per year at no cost. These are preventive services, so you must receive them from a Medicare-participating provider and the visit must be billed as a preventive service.
Ask your doctor to bill cardiovascular screenings as preventive services to ensure $0 cost. If the visit includes diagnostic services, cost-sharing may apply.
Cardiac Rehabilitation Coverage Rules
Medicare Part B covers outpatient cardiac rehabilitation programs for patients who have had a heart attack, coronary artery bypass surgery, stable angina, heart valve repair or replacement, coronary angioplasty, or a heart or heart-lung transplant. Medicare covers up to 36 sessions of cardiac rehabilitation, with the option to extend to 72 sessions if medically necessary. Each session is covered at 80% after your Part B deductible.
