Eileen,
I'm sorry you have to face this. It can be very frustrating! Here's my initial response/request for more information:

> What kinds of insurance do you have? Is this an individual policy(ies) or through an employer? Has this provider filed claims on your behalf before or since these?

> Typically managed care contracts (HMO, PPO, etc) mandate that the provider file claims on your behalf. Indemnity contracts typically don't require this so it becomes the patient
