Billing Basics

AG routinely files all necessary claims to insurance companies for reimbursement. The patient, however, is ultimately responsible for payment of the bill. It is extremely important that AG and the Austin Endoscopy Center be given all the information regarding the patient's insurance as soon as possible so that we can verify that insurance is current and determine the nature of coverage. Please be advised that there are instances when a health plan's database may not reflect current information.

Most insurance plans do not cover 100 percent of your visit. You may be expected to pay a facility fee, co-insurance or co-pay (depending on your insurance) prior to your office visit and/or procedure.

Payment of co-insurance, co-pays and deductibles may be made with cash, check or credit card, including Master Card, Visa, American Express or Discover.
