Patients Share Of Expensive Specialty Drugs Is Rising

May 07, 2012

When Kathi Ryness's multiple sclerosis worsened in 2000, she began taking Avonex, a drug that helps slow the progression of the disease and reduces the number of relapses. At the time, her health plan covered the drug in full.

But in 2009, she and her husband, Gary, were forced to switch plans. Under their new coverage, the Alamo, Calif., couple owed $660 every four weeks for the weekly Avonex injections, 30 percent of the $2,200 cost. Within a year, the cost went up again, leaving Kathi, who is now 62, and Gary, 66, on the hook for $800 every four weeks.

The coinsurance was killing them. "It was a choice between that and eating," says Gary Ryness.

Working with an insurance consultant, they switched from a preferred provider organization to a health maintenance organization that didn't have coinsurance charges for self-injectable drugs such as Avonex. Now, they pay nothing for the drug.

"Everybody has different ways of classifying these drugs," Gary says.

In coming years, experts say, more people will have to navigate the confusing and expensive terrain of such "specialty" medications.

While most drugs are made from chemicals and can have generic as well as brand-name versions, a typical specialty drug is biologic -- that is, derived from living organisms -- and has no substitute. In addition to treating MS, these drugs are used for such complex, serious conditions as cancer, rheumatoid arthritis and Crohn's disease. Growth in spending on specialty drugs is far outpacing spending on traditional drugs, and many new ones are in the pipeline.

"In the next five to 10 years, the consensus of all the experts we spoke to was that a much larger proportion of consumers will be eligible for some kind of specialty drug," says Ha Tu, a senior researcher at the Center for Studying Health System Change. She was the lead author on a recent report about managing spending on specialty drugs.

Health plans' spending for each patient using these drugs often exceeds $1,200 per month, according to the center's report. Although they account for just 1 percent of prescriptions, specialty drugs make up 17 percent of drug spending, according to IMS Health, a health-care information and services company.

Employers that provide their workers with health insurance are struggling with how to manage these costs.

Many plans have placed specialty drugs in a tier where, instead of a flat co-payment -- $20, $50 or some other amount -- patients must pay a percentage of the medications' cost. For people who need specialty drugs, that can amount to tens of thousands of dollars annually.

Some plans cap the amount a patient must pay out-of-pocket for specialty drugs at $1,000 or $2,000 annually, says Allan Zimmerman, national pharmacy practice leader in the human resources group at PwC, a business-services company formerly known as PricewaterhouseCoopers.

Employers also seek to reduce costs through intensive case management, providing their workers with education and coaching about specialty-drug dosages, side effects and adverse reactions, says Julie Stone, a senior consultant with benefits consultant Towers Watson.

One potentially useful strategy is called value-based insurance design (V-BID). This approach ties employees' out-of-pocket costs to the value of a medical service: Treatments that are deemed to provide important clinical benefits cost employees less than ones that are less effective; some may even be free.

According to a survey by human resources consultant Mercer, 17 percent of all employers with at least 500 workers used value-based design provisions in 2011, often with medications to treat chronic conditions such as diabetes, high blood pressure and high cholesterol. 

Now businesses are considering whether the same strategy might work with specialty drugs, says A. Mark Fendrick, director of the University of Michigan's Center for Value-Based Insurance Design.

"V-BID would make high-value interventions more accessible, and in some instances would make it more difficult for people to get unproven specialty drugs," he says.

The approach doesn't determine what's covered and what's not, he says. "It tries to nudge people to get services that produce value."

Still, specialty drugs present challenges, say experts. 

Take multiple sclerosis. "Because the drugs affect people differently, the question of value would be open to interpretation," says Bari Talente, vice president of state and local government relations for the National Multiple Sclerosis Society.

No employer has yet decided to apply V-BID to specialty drugs, says Fendrick. But as they grapple with managing drug costs for some of their sickest employees, some may implement it soon, he says, possibly even for next fall's open enrollment season.

Like Kathi Ryness, many patients who rely on specialty drugs are coping with very serious, long-term medical conditions. "Consumerism" - encouraging patients to shop wisely for health care - doesn't really apply when such patients need drugs for which there are few or no alternatives, says Stone.

"With people as sick as the patients we're talking about, I don't think they're going to say, 'Is there a less expensive injectable drug I can take?' " she says. "It's a whole different dynamic."
