I recommend identifying the specific PPO options that are available to you in Ohio. Then, it would make sense to determine which of these, if any, exclude orthognathic surgery coverage. The insurance companies should be able to provide you with a comprehensive document providing detailed information about the policy coverages. The staff member at Arnett Gunson should be able to provide you with information about their experience with different PPO brands (United, Anthem, etc.). I think that considerations might include easy of pre-approval, maximum covered amount for surgery, deductible amount, and copayment/coinsurance level. If you get this information, then you might assess which policy makes sense for you, given your overall health insurance needs.
