UnitedHealth Group plans to stop requiring doctors to get approvals for an array of procedures, tests and services, cutting back on a process detested by physicians and patients.

UnitedHealth, parent of the biggest U.S. health insurer, said the changes will slash the number of reviews by nearly a third starting later this year. Doctors have long complained about the paperwork they must complete to get insurers’ permission for care, which can lead to delays and denials.

UnitedHealthcare will stop requiring signoffs for tests including echocardiograms, some chiropractic care and certain outpatient surgeries. Also on the list is some outpatient therapy.

The insurer said it is using technology backed by artificial intelligence to help reduce the need for pre-authorization reviews. Or so they claim.
