KEY POINTS

Two years after Express Scripts, the giant pharmacy manager, threatened to remove PillPack from its nationwide network, the company is doing the same thing to CareZone, a venture-backed start-up that delivers medications to customers' doors. 

It's a troubling trend for emerging companies that rely on large pharmacy benefit managers (PBMs), which sit between insurance providers and pharmacies and help determine the drugs that insurers will cover and at what price.
