If you have private insurance you will be responsible for payment at the time of your visit with a check, credit card, HAS card or cash.

We will provide you with the necessary forms for you to submit to your insurance to receive a reimbursement according to your out-of-network benefits. All insurance companies have policies regarding seeing doctors that are not participating in their network.  They may reimburse a percentage of the cost of that visit, but the percentage of reimbursement varies between insurance companies. Reimbursement is related to how much they think a visit should cost as well as how much of a deductible you have. We advise you to talk to your insurance company to find out more information on how much or what percentage they are likely to reimburse based on the expected procedure codes.
