After he was diagnosed with diabetes a few years ago, Rob Kilbourn and his doctor settled on a pill that controlled his blood sugar perfectly. Eight months later, his health insurer took it off the list of drugs it pays for, sending him into a weekslong scramble for a substitute that would work as well.
Now he has to inject his meds in addition to taking a pill, and it took several doctor visits and lab tests to find the right combination.
"I went from taking a pill working wonderfully and now I'm injecting myself. It is frustrating that our health care is being determined by insurance companies and not by our doctors," said Kilbourn, of Lakeville.
Nearly a half million Minnesotans have diabetes, and hundreds of them go through this ordeal every year, sometimes more than once, when insurers update their drug formularies. But the problem extends far beyond diabetes, with thousands of Minnesotans battling chronic conditions such as depression, asthma and high blood pressure forced to switch medications.
The changes can mean higher costs for new drugs and more co-payments for office visits to get new prescriptions and lab tests. They also can lead to medical complications as patients transition from one drug to another, doctors say.
"It is always worrisome when you are having to switch someone from a drug that they are on," said Dr. David Thorson, a family practitioner at Entira Family Clinics in White Bear Lake. "Medically you would never do that if you didn't have to."
Medication switches are driven by the same market forces that can cause higher drug prices. Health insurers rely on pharmacy benefit managers (PBMs) to negotiate deals with drug companies, which pay rebates back to the insurers in exchange for higher sales, especially if a drug is selected exclusively among competitors for the formulary.
Recently, U.S. Health and Human Services Secretary Alex Azar, himself a former drug company executive, said that PBMs have an incentive to select higher-priced drugs because they earn higher fees if they select drugs that have higher rebates.
