Health plans under major U.S. insurers said Monday they have voluntarily agreed to speed up and reduce prior authorizations – a process that is often a major pain point for patients and providers when getting and administering care.

Prior authorization makes providers obtain approval from a patient’s insurance company before they carry out specific services or treatments. Insurers say the process ensures patients receive medically necessary care and allows them to control costs. But patients and providers have slammed prior authorizations for, in some cases, leading to care delays or denials and physician burnout.
