Why Do Insurance Companies Deny Proton Beam Therapy Claims?

Insurance companies are for-profit businesses and, as such, their first concern is their bottom line. While proton beam therapy offers promising results, it may come at a higher cost than standard radiation therapy. Despite its proven efficacy, many insurance companies deny coverage for proton therapy, posing a challenge for patients seeking this advanced treatment. As a policyholder, you trust insurance companies to fulfill their obligations when you need them. Regrettably, insurers don’t always act in good faith and may fail to meet their legal duties.

Insurance companies often classify proton beam therapy as experimental or investigational, establishing policies that result in automatic denials of coverage. This rigid approach overlooks the unique circumstances of individual patients and dismisses their specific needs. Such blanket denials can have severe consequences for patients who rely on this therapy to fight cancer. Courts have recognized this as a clear example of insurance bad faith, and plaintiff awards in these cases can be in the millions. When an insurer unfairly denies, underpays, or delays payment of a claim, it acts in bad faith.  

If your insurance company denies your proton beam therapy coverage, you can fight for your benefits with the help of an experienced attorney.

Is Proton Therapy Covered by Insurance?

Every insurance company’s policy coverage is different. This is because they establish guidelines for evaluating coverage requests. When it comes to proton therapy, insurers sometimes have clinical guidelines that are outdated or not based on current standards of medical care.

Insurance companies do not universally provide coverage for proton therapy to all individuals. Sometimes, you have to fight for it.

Eligibility for proton therapy treatment is typically limited to cases where the tumor is located near important organs, such as the lungs, neck, brain, head, heart, gastrointestinal tract, or spine. Even if a patient meets the necessary qualifications, there is still a possibility that an insurance company may deny a proton therapy claim.

Why is Proton Therapy Not Covered by Insurance?

How to Fight a Proton Therapy Insurance Denial

If your insurance company denies coverage for proton beam therapy, you can challenge their decision through appeals. You may be led to believe proton therapy is not covered by your insurance and wonder why. The insurance company may use the term “request for review” of your denial instead of “appeal,” but the latter term is more commonly used by most people, so we will use it here. Engaging the services of an experienced California proton therapy denial lawyer can significantly enhance your chances of building a compelling case and successfully navigating the appeals process.

Here are some steps you can take during the appeals process:

1. Know the Details of Your Health Insurance Policy

Before initiating the appeals process, it is important to understand your insurance policy comprehensively and the requirements for challenging the insurer’s decision.

Begin by familiarizing yourself with your specific type of health insurance plan, such as a Health Maintenance Organization (HMO) or Preferred Provider Organization (PPO). Additionally, ascertain the reason for the insurance company’s refusal to cover proton therapy as stated in the denial notification. This information will be the foundation for your appeal. Furthermore, gather information regarding the insurer’s unique appeals process and the steps you must take to challenge their decision. Being well-informed will greatly enhance your ability to navigate the appeals process effectively.

Our team at Kantor & Kantor knows that you may feel overwhelmed in trying to understand all the information in your health insurance policy. Trust our California proton therapy lawyers to understand what your policy will cover and build a strong legal case.

We’ll address all of the legal matters so you can focus on fighting your cancer and spending time with your loved ones.

2. Get a “Letter of Medical Necessity”

To effectively navigate the appeals process and increase your chances of obtaining coverage for proton therapy, explore your options and engage knowledgeable medical professionals about endorsing this treatment. Finding an oncologist with expertise in proton beam therapy is essential.

If your insurance company denies coverage based on the claim that proton therapy is not medically unnecessary, you can request a “Letter of Medical Necessity” from your doctor. This statement can significantly strengthen your case and persuade insurers of the essential nature of this treatment. This letter should comprehensively explain proton therapy and should highlight why your doctor recommended it as the preferred procedure over alternative options, such as typical radiation treatment or other treatment that could pose more risk.

Our proton therapy lawyers know what strategies work to successfully explain why this treatment is necessary. We can provide guidance regarding the content of your letter. This documentation may even be central to a lawsuit if your proton therapy denial case goes to court.

3. Gather Documentation to Support Your Appeal

To strengthen your position before commencing the appeals process, it is crucial to gather all relevant documentation that can provide substantial support for your case.

This documentation may include:

  • Record of communications with physicians and health care providers. especially recommendations for proton therapy
  • Evidence of previous treatments, health complications, and appointments with physicians
  • Evidence of communication with the insurance company, including email correspondence and any notes you may have related to phone conversations.

This comprehensive evidence can overturn the insurer’s decision to deny coverage and increase the likelihood of a successful appeal.

4. Submit Your Appeal with a Formal Letter

When you embark on the appeals process (or, as your policy may call it, a “request for review”) for a proton therapy denial, the final crucial step is to compose a well-crafted appeal letter and submit it to your insurer. This letter should contain all the necessary information to substantiate the need for the proton beam therapy procedure and demonstrate its potential benefits in your case.

You can try to write an appeal letter yourself, but there is a lot at stake when your fight for coverage could be a life-or-death battle. That’s why you should work with our highly experienced proton therapy denial attorneys at Kantor & Kantor.

The following are important elements in this step:

  • Address the appeal letter to the appropriate individual or department within the insurance company. Finding the correct recipient may take some research.
  • You must send the appeal letter in hard copy rather than through email or other delivery methods. Traditional mail is the accepted and valid form of initiating the appeals process.
  • Within the appeal letter, provide comprehensive details that support your case to win an appeal of your denial of proton beam therapy treatment.
  • Clearly outline your physician’s reasoning for recommending proton therapy and emphasize why this procedure is ideal for treating your type of cancer.
  • Highlight the unique benefits and advantages that proton therapy offers in your
  • Include pertinent information about your medical history to bolster your appeal of the proton therapy claim denial. This may involve explaining previous cancer treatments that did not yield the desired outcomes or detailing specific medical conditions for which proton therapy has demonstrated remarkable effectiveness.

5. Consult Medical Research to Prove Why Proton Therapy Is the Ideal Treatment for You.

Our attorneys at Kantor & Kantor know the value of both medical research and individual medical records in an appeal for a denied claim.  Extensive studies by medical researchers show that proton beam therapy (PBT) is the preferred treatment compared to traditional radiation: the efficacy is equivalent, and the side effects are fewer. The Mayo Clinic alone has done 37 studies on PBT.1 And, with less damage to surrounding tissue, the long-term side effects of PBT may be less than traditional radiation, too. What does this mean to your denied insurance claim? To support the appeal of your proton treatment denial, you can include medical documentation related to your individual treatment recommendations and to PBT in general. You may be able to show how costs related to side effects could be lower — offsetting the initial costs of PBT.

Furthermore, if you have fewer side effects, you suffer less during the treatment of your cancer. That’s a major reason why providers recommend PBT. It is an obvious choice when overall patient wellness is at stake.

Providing results of medical studies conducted by respected cancer centers or other researchers in relevant positions may be important to your appeal. It can help make your argument for why your claim for proton beam therapy should not be denied. Our attorneys at Kantor & Kantor will guide you in collecting data and can do so on your behalf. We provide here a glimpse at the available recent research on PBT.

The number of patients receiving proton beam therapy has increased over the past decade. Researchers found that almost 6 million breast and prostate cancer patients received PBT between 2004-2018.2 Medical providers specializing in the treatment of cancer at the University of Pennsylvania Roberts Proton Therapy Center have treated thousands of prostate cancer patients since 2010. They explain concisely why they chose this treatment rather than traditional radiation. Not only does its focused treatment leave healthy surrounding tissue unharmed, but Penn Medicine providers note that “[t]reatment sessions are quick, painless and result in minimal side effects for the vast majority of patients.”3

Oncology professors at the University of Pennsylvania in the Perelman School of Medicine and at the University of Washington St. Louis School of Medicine published a study in JAMA Oncology.4 They show that fewer side effects from PBT result in fewer unplanned hospitalizations. This reduction in the need for additional health care means fewer insurance claims, too. That lowers costs for insurance companies. Companies sometimes deny claims simply to protect their bottom line. When you show that future added costs related to radiation side effects may be avoided, you may get their attention.

At this point in the process, if you haven’t turned to a skilled legal professional, you should. A significant amount rides on winning your appeal of the insurance company’s denial of your proton therapy claim: your health, your future, and possibly your life.

6. Consider Hiring an Experienced Insurance Claim Denial Attorney

If you haven’t already done so, you should hire an attorney with the skills and experience needed to fight a proton beam therapy claim denial. Navigating the appeals process can be daunting, especially for individuals unfamiliar with the necessary steps. Any missteps along the way may jeopardize the chances of a successful appeal and result in further delays in receiving treatment.

Our California proton therapy lawyers have specialized knowledge about this area and will provide you with essential expertise as they build your proton beam therapy denial case. They can guide you through each step, increasing your chances of a favorable outcome and facilitating access to the necessary treatment essential for your health.

Is Your Proton Therapy Denial Governed by Federal Law?

ERISA is Highly Complex and Requires Specialized Legal Knowledge

If your proton beam therapy claim denial case isn’t complex enough, there’s yet another wrinkle: Which law governs your case, federal or state? The answer to that question lies in the answer to one simple question: Did you purchase your health insurance individually, or was it part of an employer-sponsored plan? If the latter is the case, then a federal law known as ERISA will apply.

Health insurance plans offered by employers are subject to regulation under the federal Employee Retirement Income Security Act (ERISA) of 1974. ERISA law governs employer-sponsored health plans, and its administration and enforcement fall under the responsibility of the U.S. Department of Labor. One of the key aspects of ERISA is the establishment of minimum standards for employer-sponsored health insurance, encompassing documentation, reporting, and fiduciary requirements.

With the help of our ERISA attorneys, you can confidently challenge a claim denial for proton therapy. We understand the nuances of ERISA cases and have exceptional knowledge of complex ERISA laws and legal cases.

In California, policyholders can seek legal remedies under the California Insurance Code and Fair Claims Settlement Practices Regulations.
