Insurers And Government Are Slow To Cover Expensive CAR-T Cancer Therapy
Patients whose blood cancers have failed to respond to repeated rounds of chemotherapy may be candidates for a new type of gene therapy that could send their cancers into remission for years. But the two approved therapies, with price tags of hundreds of thousands of dollars, have roiled the insurance approval process, leading to delays and, in some cases, denials of coverage, clinicians and analysts say.
The therapy involves collecting patients' own T cells, a type of white blood cell, genetically modifying them, and then infusing them back into patients, where they hunt down and kill cancer cells. Known as CAR-T cell therapy, it's been characterized as a "living drug" by some researchers.
Researchers report that some critically ill patients who received the therapy have remained cancer-free for as long as five years.
"This is what patients need," says Dr. Yi Lin, a hematologist who oversees the CAR-T cell practice and research for the Mayo Clinic. "With the likelihood of getting patients into durable survival, we don't want to deny them the therapy." She says she receives no personal financial support from the drugs' makers.
But the treatment comes at a cost — the drug treatments are hugely expensive. Kymriah and Yescarta cost $373,000 for a one-time infusion to treat adults with advanced lymphomas, while Kymriah costs $475,000 to treat acute lymphoblastic leukemia in children and young adults. That's the cost of the drug itself; in addition, many patients experience serious side effects that can land them in a hospital intensive care unit for weeks, pushing treatment costs to more than $1 million.
All of this gives government and private insurers pause.
Most commercial insurers are covering CAR-T cell therapies now, but they do so on an individual basis, writing single-patient agreements each time, say cancer specialists. Large insurers that are already familiar with complicated therapies like stem-cell transplants are getting speedier at handling requests for CAR-T cell treatment, they say. But that's not always the case at smaller or regional plans, where delays can add weeks to the approval process.
"A request for CAR-T may end up with somebody on the payer authorization team who doesn't understand the technology or the urgency of the request, when somebody has only weeks or months to live," says Stephanie Farnia, director of health policy and strategic relations at the American Society for Blood and Marrow Transplantation.
Farnia is in contact with many of the more than 50 medical centers that are authorized to provide treatment. The process of getting to a treatment center and evaluated for therapy is involved, she says. "To then be substantially delayed due to paperwork is incredibly frustrating" for patients.
Medicare and Medicaid often pose greater coverage challenges than do private insurers, according to insurance experts.
Some Medicaid programs don't cover the treatment, says Dr. Michael Bishop, director of the cellular therapy program in the hematology/oncology section at the University of Chicago. Medicaid, the state-federal health program, covers children in low-income households and some adults.
"Medicaid has been very tough," he says. "Certain states just deny coverage — even states with balanced budgets."
States have to evaluate the cost as well as the drugs' effectiveness, says Matt Salo, executive director of the National Association of Medicaid Directors.
"Medicaid is a finite pot of money, and it's stretched threadbare even on a good day," he says.
People who are on Medicare, the health insurance program for people age 65 and older and some people with disabilities, typically haven't faced coverage denials to date, clinicians say. But the government's reimbursement rates are raising concerns for providers.
Last spring, Medicare announced payment rates for providers who administer Yescarta and Kymriah on an outpatient basis. The payments would more than cover the costs of the drugs. Medicare beneficiaries' out-of-pocket costs would be capped at $1,340 plus the beneficiaries' Part B deductible (if that hasn't already been met), the agency says.
The problem with this plan? Facilities typically provide treatment on an inpatient basis, not outpatient, because of the potential for severe, systemic side effects.
"There's a lot of toxicity and questions about whether it can even be provided in an outpatient setting," says Gary Goldstein, the business manager at the blood and marrow transplant program at Stanford Health Care in Stanford, Calif.
For inpatient care, "CAR-T cell therapy ... would be paid at a much lower amount compared to outpatient hospital use," according to officials at the Centers for Medicare & Medicaid Services.
The agency is considering how to handle payment for inpatient CAR-T care for the fiscal year that starts in October. For now, some medical centers are absorbing whatever Medicare doesn't pay.
"How can you tell a patient who's 66, 'If only you'd gotten lymphoma when you were 64'?" Goldstein asks.
But the current approach can't continue indefinitely, he says.
"Even if there aren't any centers that are making that decision today, if coverage doesn't change for Medicare, it absolutely is going to be a problem tomorrow," says Goldstein.
