Can a hospital keep a refund I paid for a co-pay if my insurance company paid the whole bill?
Question Details: They applied the refund to a bill they said I owned from 20 years ago.
The hospital that you are writing about cannot legally keep an overpayment for a current medical bill and apply it to some alleged bill that you owed that would be time barred from being collected upon by your state's statute of limitations. Given what has transpired, you should consult with your insurance carrier about the improper debiting of overpayments by the health care provider you went to.
