  7. The most appropriate procedure, supply, equipment or service which can safely be provided. The most appropriate procedure, supply, equipment or service must satisfy the following requirements:
    1. There must be valid scientific evidence demonstrating that the expected health benefits from the procedure, supply, equipment or service are clinically significant and produce a greater likelihood of benefit, without a disproportionately greater risk of harm or complications, for you with the particular medical condition being treated than other possible alternatives; and

  8. Is not conducted for research purposes, unless as part of a covered clinical trial;

Preferred Provider Organization (PPO)

Qualified Medical Child Support Order (QMCSO)

An order by a court resulting from a divorce which designates one parent to pay for a child’s health coverage and which meets all of the federal legal requirements for this type of order.

Reasonable Charge/Reasonable and Customary Charge

For covered services performed by a provider participating in the PPO Network, the maximum Reasonable and Customary Charge will be the Contract Rate that the provider has agreed to accept as reimbursement for the provided covered services from the PPO Network. For covered services performed by a provider not participating in the PPO Network, the maximum Reasonable and Customary Charge will be based on the applicable PPO Network non-participating provider rate or fee schedule, an amount negotiated by the PPO Network or a third party vendor which has been agreed to by the non-participating provider, an amount derived from the total charges billed by the non-participating provider, an amount based on information provided by a third party vendor, or an amount based on reimbursement or cost information from the Centers for Medicare and Medicaid Services (CMS).

Important: Because the PPO Network (Anthem Blue Cross) may change its determination of what is a Reasonable and Customary Charge for any particular treatment or service at any time, you should check with both the provider of service and Anthem before you consent to receive treatment or service from a Non-PPO Network Provider. Ask both the provider of service and Anthem what the maximum allowed amount is for the treatment or service you are requesting. Neither Anthem nor the Fund will give notice of these changed calculations; so it is very important that you inquire about them. You should do this even if you have had the same treatment or procedure in the past, because Anthem may have changed the maximum allowed amount since your last treatment. A change in what Anthem considers to be Reasonable and Customary Charge and what will be the maximum allowed amount for a treatment or service could mean a change in hundreds or even thousands of dollars in your out-of-pocket cost.

Registered Nurse

Retiree/Retired Participant/Retired Employee
