How does Medicare handle coverage for experimental treatments or clinical trials?

Question

Nancy Suozzi-Vidal · Accepted Answer

Routine services that would normally be covered under Medicare may be covered for participation in a clinical trial. But, clinical trial services and experimental treatment will not be covered. Any covered services would most likely be subject to prior approval. Likewise, your OOP responsibility would apply for covered services. Your provider should work with Medicare or other Medicare plan coverage carrier regarding specific criteria to actually participate. I also recommend the patient discuss with a carrier nurse to determine any patient responsibilities.

Medicare does not typically cover experimental treatments. There may be coverage for some of the testing in the trials, but I would not bank on Medicare covering anything for you.

Medicare generally does not cover experimental or investigational treatments, meaning services that haven’t been proven effective under Medicare rules. However, Medicare does cover routine patient care costs for beneficiaries who participate in approved clinical trials, such as doctor visits, labs, and hospital services that would normally be covered. The experimental drug, device, or procedure itself is usually not paid for by Medicare. Coverage rules can differ slightly under Medicare Advantage plans, so it’s important to confirm details before enrolling in a trial.

The question is, how does Medicare handle coverage for experimental treatments or clinical trials? Let’s be clear, Medicare Advantage is not going to pay for those. They’re just not going to, so know that. Medicare Original may pay for it, depending on how the procedures are coded and if it’s in the CMS regulations. There’s a lot of lobbying and fast tracking of drugs, and it’s far better than it was 25 years ago. If it’s going to be approved at all, it will be through Original Medicare and a supplemental policy.

So here’s the third option. If you’re under 65 in California, and even elsewhere, I can sell you a policy that if you get a bad diagnosis like cancer, or whatever, or LMP, or Leigh’s disease, or Parkinson’s disease, or whatever it is, you know, prostate, whatever, these policies pay you $100,000. You can go use your $100,000 to buy whatever drugs or participate in whatever clinical trial you want. It’s beautiful, but you can’t do it in California after you turn 65. I can sell them in other states, but you know, it’s just the facts. That’s why I want to have conversations with people before they turn 65, like when they’re 60, so that we can do the financial planning through this. We can look at long-term care. There is so much that Medicare cannot possibly pay for. It’s $341,000 is what you and I, when we turn 65, can reasonably expect to pay out of pocket for things like experimental treatments, clinical trials, and home care.

Joshua Allen · Answer

Experimental treatment or investigational device being tested in trial is typically not covered by Medicare. However, Medicare does cover routine costs associated with qualifying for clinical trials, but not the investigational treatment itself. These costs include doctor's visits, hospital stays, diagnostic texts, and medical care related to side effects. To know if Medicare will cover a specific service, it is best to communicate directly with the provider of that service. For example, to know if Medicare will cover a diagnostic test, it is best to ask the provider of that diagnostic test.

You will have to pay out of pocket for anything of an experimental nature. However, should the CDC or the Center for Medicare and Medicaid Services (CMS) approve that treatment in the future, it would then be paid for.

Medicare usually does not cover experimental treatments or clinical trials. Medicare will typically only cover the routine costs associated with participating in certain approved clinical trials, including items and services that would normally be covered if not participating in the trial, such as standard medical care and treatment of trial-related side effects.

Medicare doesn’t cover clinical research itself; it may cover certain treatments or services you get as part of participating in the trial. You will need to check with your insurance carrier to ensure you can move forward with the clinical research.

David Ryerson · Answer

Typically, experimental treatments and clinical trials are not considered to be a covered benefit under original Medicare. In some cases, your provider could request, based on medical reasons, for the specific need to be covered, but in general these things are not covered benefits.

Historically, Medicare will not cover experimental treatments. 

Medicare may cover clinical trials, labs, Dr. visits, and costs associated with the clinical trial. Medicare may not cover additional costs outside of the clinical trial. It is suggested that pre-approval may be best practice before beginning some clinical trials.

Diane Poythress · Answer

Medicare generally does not cover experimental treatments or the costs of clinical trials, but it may cover the "routine costs" of qualifying clinical trials. Routine costs are those that would normally be covered by Medicare if the patient were not participating in the trial, such as standard medical care and treatment of trial-related side effects.

Brian Leichner · Answer

Medicare does not cover experimental treatments.  It covers Hospitals when inpatient using Part A and doctors using Part B.  Drugs are covered under Part D, but must be on the formulary, so you probably won't find coverage for experimental meds either.  

To talk to you about what could be covered; you can buy policies that pay directly to you.  Policies like this pay for being unable to take care of yourself, cancer, accidents, hospital and other plans that pay you cash and then you can use that cash to pay for experimental procedures that you seek.

Bob Callahan · Answer

Generally speaking, Medicare will cover the routine costs associated with qualifying for a clinical trial (i.e. lab tests, dr visits, etc...), but will NOT cover the trials whether it be for a drug, device, or service/procedure. There are very rare exceptions for slightly greater coverage (i.e. if part of a CED or IDE Study), but those situations are truly exceptional.

Fred Manas · Answer

Medicare generally covers routine costs associated with participation in qualifying clinical trials. This includes costs like hospitalization, outpatient services, & medical care for treatment-related side effects, if these are things Medicare would normally cover. However, Medicare doesn't typically cover the experimental treatment or drug itself, or costs specifically related to the clinical trial research. 
Here's a more detailed breakdown:
What Medicare Does Cover:
Routine costs:
This includes the costs of services & procedures that would be covered by Medicare if the patient weren't participating in a clinical trial. 
Medical care for treatment-related side effects:
Medicare will cover medical care needed to address complications or side effects arising from participating in the clinical trial. 
Some costs related to investigational devices:
Medicare may cover costs related to investigational devices if certain conditions are met. 
Coverage with conditions:
In specific instances, Medicare may reimburse for investigational treatments under certain conditions, notes the National Institutes of Health (NIH). 
What Medicare Does Not Cover:
Experimental treatment costs:
Medicare typically doesn't cover the cost of the experimental drug, device, or treatment itself, or the costs associated with the research aspect of the trial. 
Costs not covered by Medicare otherwise:
If a cost is not covered by Medicare outside of a clinical trial, it is unlikely to be covered as part of the trial. 
Important Considerations:
Clinical trial must meet requirements: The clinical trial must meet specific criteria & have therapeutic intent to be covered by Medicare. 
Prior authorization may be needed: Some Medicare plans may require prior authorization for certain clinical trial costs. 
Patient cost-sharing: Even with Medicare coverage, patients may still have out-of-pocket costs for co-insurance and deductibles. 
Discussions with plan administrator to understand what is & isn't covered.

Medicare generally covers the routine costs of clinical trials and may cover certain experimental treatments or services, especially those that are part of a "Coverage with Evidence Development" (CED) study. Routine costs include services that would normally be covered by Medicare if not part of a clinical trial.

The answer to this question has several moving parts, and demands careful consideration.

Generally speaking Medicare does cover certain clinical trials and experimental treatments, but only unders certain conditions.

In my Medicare insurance practice I have dealt with clients undergoing monoclonal antibodies for the treatment of early onset Alzheimer's disease, this treatment is covered.

Regarding routine costs associated with a qualified clinical trial, those would be covered. 

Things like doctors visits, hospital stays, lab tests, and other standard medical services that normally would be "Medicare allowed expenses' that you would normally receive even if not participating in a trial, those would be covered. Treatment of side effects or complications from trial participation, would be covered as well.

On the other hand, other research-only items, and investigational treatment or devices would usually not be covered. Exceptions might apply. 

Check with your trial sponsor if the trial you are about to sign on to is a Medicare-approved clinical trial. or call 1-800-MEDICARE also visit www. medicare.gov
