For example, if an employer is expected to incur a 20 percent increase in diabetes drug spending in 2017, Express might set a per person/per year cap of no more than a 10 percent increase for its employees. Should diabetes spending hit that cap for a plan participant, Express Scripts would cover all excess costs.
"If they go over the cap, we're on the hook dollar for dollar," Glen Stettin, chief innovation officer at Express Scripts, said in a telephone interview.
For many customers diabetes costs will be "significantly less than what they've experienced in the past several years and significantly less than what would have been projected for the future had they not participated in this program," Stettin said.
Prescription benefit managers, which negotiate drug benefits for health plans and employers, have become increasingly aggressive players in efforts to hold down prescription drug costs.
They achieve this by demanding steep discounts from drugmakers in exchange for including their medicines on preferred use formularies, and by limiting use of expensive new medicines to patients who fit certain criteria.
The Express Scripts program also aims to improve patient compliance rates, in part by allowing them to receive 90 days of drugs at one time rather than a one-month supply, either through the Express Scripts mail order pharmacy, or through more than 10,000 pharmacies across the United States, including all Walgreens pharmacies.
More than 29 million Americans have diabetes, according to the U.S. Centers for Disease Control and Prevention.
Patients not taking their medications regularly, often due to high costs or inconvenience, is a constant lament of physicians and can lead to serious and expensive health complications.
