Please notify us immediately to discuss this further.

What if I accidentally eat or drink something after the cut-off?
If you have something to eat or drink after the cut-off, please notify our office immediately. Your procedure may be postponed or cancelled potentially causing you to need to repeat your prep.

How much notice is needed to cancel my appointment?
Procedure: you may be charged for a late cancellation. Office visit: In new patient forms you will sign a no show agreement outlining the notice requested. Our office is extremely busy and we appreciate you cancelling in time for another patient to be scheduled. We will work with you to get you in as soon as possible, however, it may be several weeks before the next available appointment.

Why did I receive more than one bill for my procedure?
There are multiple components involved in your procedure. You will receive a bill from our office, the location that the procedure was done and potentially an anesthesiologist or pathologist depending on your procedure.
