Yes, Medicare Part B covers cardiac rehabilitation programs, both standard and intensive, for people with qualifying heart conditions. You’ll need a referral from your doctor, and coverage is limited to 36 sessions in most cases. Here’s what you need to know about eligibility, session limits, costs, and the different program types.
Qualifying Heart Conditions
Medicare considers cardiac rehab medically necessary only for specific diagnoses or procedures. You qualify if you’ve had any of the following:
- Heart attack within the past 12 months
- Coronary artery bypass surgery
- Stable angina (recurring chest pain)
- Heart valve repair or replacement
- Coronary angioplasty or stenting (procedures to open or prop open a blocked artery)
- Heart transplant or heart-lung transplant
- Stable chronic heart failure
If your heart condition isn’t on this list, Medicare won’t cover rehab even if your cardiologist recommends it. The 12-month window for heart attacks is strict: your documented diagnosis must fall within the year before you start the program.
How Many Sessions Medicare Covers
A standard cardiac rehab program covers 36 one-hour sessions spread over a maximum of 36 weeks. That works out to roughly one to three sessions per week, depending on how your program is structured. You can do up to two sessions in a single day, but the combined time must total at least 91 minutes (a full 60-minute session plus at least 31 minutes for the second).
If you experience a significant illness or setback during your first 36 sessions and haven’t met your recovery goals, your provider can request an additional 36 sessions, bringing the total to 72. Your rehab facility handles the documentation for this extension. A completely new qualifying event, like a second heart attack or another bypass surgery, can also start a fresh series of 36 sessions.
Intensive Cardiac Rehab Programs
Medicare also covers a more rigorous option called intensive cardiac rehabilitation (ICR). These programs go beyond supervised exercise to include structured nutrition counseling, stress management, and lifestyle modification. ICR allows up to 72 one-hour sessions over a period of up to 18 weeks, a significantly faster and more concentrated schedule than standard rehab.
Only three ICR programs are currently approved by Medicare:
- Dr. Ornish’s Program for Reversing Heart Disease
- Pritikin Program
- Benson-Henry Institute Cardiac Wellness Program
These programs aren’t available everywhere, so you may need to check whether a participating facility exists near you. If you start an ICR program and switch to standard cardiac rehab partway through, your completed ICR sessions count toward your combined total of up to 72 sessions.
What You’ll Pay Out of Pocket
Cardiac rehab falls under Part B, so your costs follow the standard Part B structure. You’ll first need to meet the annual Part B deductible, which is $257 in 2025. After the deductible, you typically pay 20% of the Medicare-approved amount for each session, with Medicare covering the remaining 80%. If you receive rehab at a hospital outpatient facility, a hospital copayment may apply instead.
A Medigap (Medicare Supplement) plan can reduce or eliminate that 20% coinsurance. If you’re enrolled in a Medicare Advantage plan, your costs depend on your specific plan’s rules, though the plan must cover at least what Original Medicare covers. It’s worth calling your plan before starting rehab to confirm what your per-session cost will be.
Getting a Referral
Medicare requires that your attending physician refer you to cardiac rehab and document that it’s medically necessary. The referral must include your qualifying diagnosis. Without this documentation on file, claims can be denied. In practice, most cardiologists or surgeons will initiate the referral as part of your discharge or follow-up care, but it doesn’t always happen automatically. If you’ve had a qualifying event and nobody has mentioned rehab, ask your doctor directly.
Where Rehab Takes Place
Covered cardiac rehab must be provided in a Medicare-approved setting: either a hospital outpatient department or a physician-directed clinic. The facility must have emergency equipment on hand, including oxygen and a defibrillator, and the program must run in a dedicated space while sessions are in progress. A physician must be on the premises and immediately accessible during every session, though not necessarily in the exercise room itself.
Home-based cardiac rehab has been a growing area of interest, and a policy change finalized for 2026 allows the required physician supervision to occur virtually through real-time video for cardiac rehab services. This means a supervising doctor could monitor sessions remotely via video rather than being physically present at the facility. This could eventually expand access for patients in rural areas or those who have difficulty traveling, though the practical rollout will depend on how facilities adapt to the new rules.
Why It Matters to Use Your Sessions
Cardiac rehab is one of the most underused benefits in Medicare. Studies consistently show it reduces the risk of a second heart event and improves quality of life, yet fewer than a quarter of eligible patients complete a program. The combination of supervised exercise, heart monitoring, and education on diet, medication, and stress makes a measurable difference in recovery. If you qualify, the 36 sessions Medicare covers represent a significant investment in your long-term heart health, and the out-of-pocket cost is relatively low compared to most cardiac care.
