Most insurance company prior authorizations (referrals) can be obtained for you at the time of an office visit with one of our physicians. However, some insurance companies take up to one week to complete the authorization process. In these situations, a copy of the authorization will be mailed to your home. It is very important for you to take this authorization to the specialist's office for your appointment. If you need an extension of time or visits added to the authorization, please contact your doctor's office at least one week in advance of when you need the authorization. We can not backdate referrals.
