Briumvi Health Insurance Denial

TG Therapeutics submitted a biologics license application (BLA) for Briumvi (ublituximab-xiiy) on September 28, 2021. In March and April of 2022, the FDA received major amendments to the BLA, extending the goal date. Briumvi received FDA approval on December 28, 2022, for the treatment of relapsing forms of multiple sclerosis in adults, based on the results of the Phase 3 trials ULTIMATE I and II.  

This article addresses Briumvi health insurance coverage claims, how insurers make decisions regarding medical necessity, and what actions you can take after receiving a Briumvi health insurance claim denial. If you have received a Briumvi health insurance claim denial, contact the Law Offices of Scott Glovsky. This is a situation that can really benefit from having a strong legal advocate on your side, and Attorney Scott Glovsky has been fighting for justice for his clients for over two decades.  

How Does Briumvi Work?

Multiple sclerosis (MS) is a chronic, systemic autoimmune disorder characterized by inflammation and the degradation of the myelin sheaths that protect the nerve fibers in the central nervous system. This degradation is known as demyelination and occurs when the body’s immune system mistakenly attacks the myelin, resulting in inflammation and damage. The primary cells involved in MS are T cells, although B cells have also recently been implicated in the disease, leading researchers to explore B cell therapy as an alternative treatment for MS. 

B-cell therapy is based on depleting CD20-positive B cells. Rituximab (brand name Rituxan used to treat Non-Hodgkin’s Lymphoma, Chronic Lymphocytic LeukemiaRheumatoid arthritis, and more), ocrelizumab (brand name Ocrevus used to treat MS), and ofatumumab (brand name Kesimpta used to treat MS) are all anti-CD20 antibodies that have already garnered FDA approval.

Who Can Take Briumvi and How is Briumvi Administered?

Briumvi is not for use in children and is administered as an intravenous infusion every six months, following an initial two doses taken two weeks apart. Patients with active hepatitis B infection or a history of allergic reactions to Briumvi should not take the drug. You can find more information about Briumvi here

 Is Briumvi Expensive?

Briumvi can be considered an expensive medication for the treatment of multiple sclerosis, with a 2025 list price of approximately $88,000 per year. With insurance, the out-of-pocket costs will vary significantly, depending on your specific health insurance plan. Typical co-pays per infusion can be from $0 to $5,000. Medicare patients may pay between $500 and $2,000 per infusion, while Medicaid patients will likely pay significantly less. 

TG Therapeutics offers a co-pay assistance program for commercially insured patients to help cover co-pays. There are also patient assistance programs for those who are uninsured or underinsured and meet financial eligibility criteria. While Briumvi is expensive, it is the lowest-priced branded disease-modifying therapy available for MS patients. 

Is There a Biosimilar or Generic for Briumvi?

Briumvi is a biologic medication. Biologics are complex and produced in living cells, while biosimilar drugs are biologic medications that are very similar to an already approved biologic drug, known as the reference product. Biosimilars, like generics, are close copies; however, they are considered to have no clinically meaningful differences in terms of safety, potency, or purity. In certain cases, biosimilars can be substituted for the reference product at the pharmacy without intervention of the prescribing healthcare professional in the same way the pharmacy can give you a generic drug rather than the brand name. Learn more about biosimilars here.

Biosimilar drugs undergo a rigorous approval process from the FDA to ensure they meet the same safety and efficacy standards as the reference product. As of July 2025, Briumvi is only available as a name-brand biologic, with no biosimilar yet developed or approved. TG Therapeutics holds the patent on Briumvi, which extends through 2043, providing market exclusivity. 

 Do Insurance Companies Cover Briumvi as a Treatment for Multiple Sclerosis?

Government health insurance programs, such as Medicaid and Medicare, may provide coverage for Briumvi to treat multiple sclerosis, although coverage can vary depending on the state of residence. Medicare is the federal health insurance program for those 65 and older. The prescription drug benefits may be available through Medicare Advantage Plans (Part C) or Supplemental Plans (Part D). Patients are required to enroll separately from “regular” Medicare for a prescription drug plan. 

AnthemKaiser PermanenteBlue Shield, HCSC, Humana, UnitedHealthcare, and Aetna are commercial private insurance companies that have different coverage standards from one another. Many private insurance companies will cover Briumvi as a treatment for multiple sclerosis, provided the insurer considers the drug medically necessary

If you have received a Briumvi health insurance denial, you have the right to appeal the denial, although how you appeal will be determined based on whether you have an ERISA (Employment Retirement Income Security Act of 1974) or non-ERISA Plan. Your plan administrator can help you determine which type of plan you have. Most private employers offer ERISA plans, with the following exceptions: 

  • Religious organization plans
  • Many government employee plans
  • Individual and family plans purchased through private insurance companies like Anthem Blue Cross or Blue Shield of California
  • Individual and family plans through Covered California
  • Business plans that only cover business owners

Those with ERISA plans should file an appeal, as all administrative remedies must be exhausted. If you have a non-ERISA plan, you have more options and should speak with an attorney prior to submitting your appeal. You can learn more about ERISA plans here and non-ERISA plans here

Understanding Denials Based on Being Experimental, Investigational, or Not Medically Necessary

The goal of insurance companies is to make money, so other than denials based on lack of information, errors, and out-of-network providers, the terms “investigational,” “experimental,” and “not medically necessary” too often means that the drug or treatment is expensive and the insurance company does not want to pay. Many insurers also require prior authorization before covering an expensive drug. Prior authorization requires you to obtain approval from your insurer before it will pay for the drug. There can be some bumps along the way when obtaining prior authorization. Since there is usually more than one drug to treat any given condition, insurance companies – not surprisingly – oftentimes favor less expensive treatment options. 

Step therapy is a form of prior authorization that requires the patient to try alternative drugs (usually 2, for 60 days each) to determine whether the alternative (less expensive) drug will work. If the alternative drugs do not achieve the desired results, the insurer may revisit the original claim and approve the doctor-prescribed drug. Sometimes, there are exemptions in California for step therapies; the process can be time-consuming and complex. Your doctor fills out the Prescription Drug Prior Authorization or Step Therapy Exception Request Form.

Investigational and experimental” are additional terms sometimes used by insurers to avoid paying for an expensive drug. The policy definitions of experimental and investigational can be used when a drug is used off-label, even though doctors prescribe drugs off-label every day, and it can be both legal and appropriate. However, if the condition is not what the FDA approved the drug for, the insurer is likely to label it experimental or investigational. 

When the FDA approves a new drug, insurance company teams have their professionals including pharmacists research the drug to develop internal clinical policies that will help the insurance company decide which drugs are medically necessary under specific circumstances. Once the policies are developed, they are presented to a board of external physicians, who, unfortunately, could be motivated by financial gain or the potential to work for the insurer. This can result in overly restrictive policies regarding the approval of particular drugs. 

 What Duties Do Insurance Companies Have to Members Submitting Claims?

Insurers have specific duties when members submit claims. These include:

  • The duty to thoroughly investigate a claim request.
  • The duty to fully inquire into every possible reason that could support the request for care. 
  • The duty to promptly respond to claim requests. 
  • The duty to appoint and employ qualified medical professionals to make claim review decisions.
