Front desk lady told me that Dr. Lilly would be out of network with my 2024 insurance policy. She advised me to call UHC to clarify. After 24 minutes on the phone I was able to confirm that Dr. Lilly was indeed in network. Aurora's system flagged that my visit would be out of network and I would have to sign a financial consent form. Very frustrated to have to deal with that on the day of an appointment. Not sure why Aurora's system showed an error.
