The review of your medical records is an important part of your evaluation. Your medical records must be received at least one day before your appointment so we can prepare for your visit.

It is important to contact your insurance company before your appointment to receive approval, called "prior authorization," for your visit to our clinic. If you don't obtain necessary authorization, you will be responsible for all charges associated with your care. Please read the following "Insurance Information."/p>
Before your appointment, please review your insurance benefits. Call your insurance company or review the insurance information provided by your insurance carrier. Each insurance plan has rules that must be followed to receive full benefits. If your insurance plan requires prior authorization to see a specialist, please fax referrals and authorizations to the clinic before your appointment. If we don't receive these referrals and authorizations, you will be responsible for all charges associated with your appointment.
