Failure by the patient or their doctor to provide a proper referral or pre-authorization will result in a denial of payment by the insurance company. The patient is then responsible for paying the bill. Many of the physicians affiliated with this website are self-employed physicians and members of the medical staff at one or more hospitals and are not employees or representatives of the hospitals. Therefore, this site is not responsible for the treatment given by these doctors.
