If you are told by your insurance company or the specialist that you will need a referral, please call 398-3900 at least 48 hours ahead of time so that we may assist you in getting the proper background information to the specialist and the insurance company. Many insurance companies will not allow back dated referrals. If the insurance company does not receive the primary care provider's referral in advance, they may deny the visit or pay the specialist at a lower rate. Please have your insurance card available for reference when you call.
