health insurance and doctor billing

[wat2due]

My mother's doctor billed her insurance, and insurance over paid the doctor. Doctor supposedly returned the over paid amount, but now has billed her for the over payment. Logically, I think she needs to get a itemized statement from the doctor. Then verify it with what the insurance company paid. I understand that she can be billed for service her insurance will not pay. At the time of service I believe she was at a catstrophic level of her insurance. Am I on the correct path?

The insurance game

I find it crazy the cost of health insurance is something that congress has fixed!
