Be very careful. The "plan" described is not an insurance plan. They claim to have thousands of providers "participating" with the plan by using a major insurance company's name in the ad. The providers are not required to give the patient a discount.
Definitely check with your provider before any services are provided, and be prepared to remit payment, in full, at the time of service. You will only save money if your provider agrees to accept AccessOne's discounted amount.
Good luck.
