Prior authorization refers to when medical providers have to get approval from insurers before performing a service. Patients and providers have criticized insurance companies for denying prior authorization requests, saying that them doing so prevents or delays patients from accessing care that is recommended by their doctors.

Months after the killing of a top health insurance executive unleashed Americans’ pent-up anger over denials of medical care, the industry announced Monday that it will take action to “streamline, simplify and reduce” the preapproval process.

According to the plan, by 2027, the insurers will be sharing an electronic system to speed up treatment decisions and explain them more clearly. The number of treatments that need approval will be smaller, and approvals by one plan will be honored for 90 days if a patient changes plans.
