U.S. Health and Human Services Secretary Robert F. Kennedy Jr. said this week that several of the nation’s largest health insurers have agreed to change how they handle prior authorization, a system that often causes delays in care.

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.

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.
