Another lawsuit against Radiology Partners due to its billing practices, this time from UnitedHealthcare (again) in Arizona. Like the Aetna lawsuit in Florida, this one focuses on abuse of the No Surprises Act’s Independent Dispute Resolution process by routing in-network claims through an out-of-network subsidiary in order to make more money. Perhaps it shouldn’t be a surprise that RP is the #1 initiator of IDR claims across the whole country.
