Scripps Health review: Billing issues

My daughter was seen for a well check (which insurance covers completely) but I was sent a large bill. When I asked about it I kept getting vague answers like "we have reviewed your complaint and decided that the bill is correct and still stands". I tried messaging and even calling the billing number provided. The people were polite but completely not helpful. One even got her supervisor to try and help and basically all she said was I could try messaging again (yep, the same people that gave me vague answers previously) OR she could give me 10% off the bill. 10% isn't worth it and for them to offer that when I am disputing the whole bill is frustrating.

I finally got someone to message me back with more details on the bill. Basically the doctor wrote down that we had discussed various "diagnoses" during the visit which made them charge an additional office visit. I tried to explain multiple times that there was no diagnoses at all. Any conversations about her health were me answering HIS questions and I never sought any additional medical advice outside of the well visit. I was basically told that its too bad, because the bill is staying and there isn't anyone I can talk to (I tried to get them to let me speak to someone in person) and that my best bet was to contact the doctor and see if they would change the chart.

I just can't get over being charged because I answered his questions. It would be different if I asked him for medical advice during a well visit, but I didn't. And, at no time during the visit was I informed that by answering the questions or asking any follow up questions that it would shift to a second office visit charge.

This has been going on for 5 months! So now I am waiting to hear back from the doctor. But there has got to be a better method for billing disputes other than just a "we said it was right, the end".
