Amid increasing public scrutiny of rising insulin prices, some health insurers are taking matters into their own hands to help their diabetic members afford the lifesaving medications, AIS Health reported.

At the integrated health system HealthPartners, the members who are hardest hit by rising insulin prices are those in high-deductible health plans, says Young Fried, vice president of pharmacy plan services. But she says insulin affordability is also an issue for Medicare members who are in the Part D “doughnut hole.”

One tactic that the organization’s health plan deploys to ease the burden on members is a policy called “plan pay the difference,” Fried says. If a brand drug becomes cheaper than the generic version after rebates, “we would actually have the member pay the generic copay instead of the brand, and then we would reimburse the pharmacy the brand cost, so that they’re made whole as well,” she says.

At Geisinger Health Plan, Medicare enrollees are the ones who have the most trouble paying for their insulin, according to Jamie Miller, the health plan’s system director of managed care pharmacy. Overall, Geisinger saw its spending in the diabetes drug class rise 13.8% between 2017 and 2018, she adds.

As Geisinger works out what it wants its Medicare benefit to look like in 2020, Miller says one goal is to make insulin more affordable for its senior members. Thus, the health plan is considering adding a sixth, “zero-dollar” tier to its Part D formulary where it would put insulin and select other drugs.
