Thank you for choosing Saunders Oculoplastic Surgery, PSC for your treatment. All copay, co-insurance and deductibles are due 1 week prior to your procedure. We attempt to be as accurate as possible in calculating the amount due. However, adjustments are made by insurance companies. If there is an overpayment by you, we will refund upon receipt of EOB. If you have a balance due, we will send a statement upon receipt of EOB.
