Payments & Insurance


All payments are due at the time services are rendered.  Cash or checks are the preferred methods of payment; however, payment by credit card will be accepted. Please note, effective 1/1/2023, a 3% processing fee will be added to credit card payments.  Please also note that flexible spending/health savings cards as well as debit cards are not able to processed in our office.


Dr.  Mattox is no longer an in-network provider with any insurance companies.  If you wish to have charges filed to insurance, our office is more than happy to provide you with documentation you need to seek reimbursement from your insurance  IF your out-of-network deductible is lower than the amount of the services being provided.  Please note that your in-network and out-of-network deductibles are separate!

Please note that Dr. Mattox is not in-network with SoonerCare, TriCare, Medicare, Medicaid, or any private health insurance companies.
