Two months after a cyberattack on UnitedHealth Group subsidiary Change Healthcare halted payments to some doctors, medical providers say they're still grappling with the fallout, even though UnitedHealth told shareholders on Tuesday that business is largely back to normal.

"We are still desperately struggling," said Emily Benson, a therapist in Edina, Minnesota, who runs her own practice, Beginnings & Beyond. "This was way more devastating than COVID ever was."

Change Healthcare, a business unit of the Minnesota-based insurance giant UnitedHealth Group, controls a digital network so vast it processes nearly 1 in 3 U.S. patient records each year. The network is a critical conduit for shuttling information between most of the nation's insurance companies and medical providers, who submit claims through it to get paid for treating patients.
