Ambulatory Hospital Procedures


Our office will handle communication with your insurance company to obtain preauthorization for your procedure. We cannot move forward with scheduling your surgery without getting this approval.

We do not receive fee quotes for the procedure or the hospital itself. If you have questions about deductibles, co-insurance, or hospital coverage, please contact your insurance carrier directly.

Please read, sign, and return the attached explanation of coverage to the office at the time of your pre-surgical appointment.

What is ambulatory surgery?

This means you are leaving the hospital the same day as your procedure. Someone must be there to escort you home after your procedure. If this cannot be arranged, you may have to be observed overnight in the hospital.

What is same day admission?

It means that you will be admitted for your surgery and then kept overnight for observation. If you need to be observed overnight for medical reasons, we will inform you.

Do I need medical clearance?

All patients should obtain medical clearance as per Dr. Westreich’s instructions.

Even young healthy patients need routine blood work and a physical examination showing that their heart and lungs are healthy. This helps to avoid problems, delays, and last minute cancellations on the day of your surgery.

For all surgery locations, a clearance letter from the examining physician is requested. A preoperative clearance request form is attached. Please give it to your doctor. If you do not have a primary care physician and would like a recommendation for this service, please ask our office.

Do I need pre-surgical testing?

If you decide not to obtain private medical clearance, a pre-surgical testing appointment is required at the hospital. Our office will help you to coordinate this as needed.

Medications to avoid

You should not take Aspirin, Motrin, Advil, Naproxen, or other pain medications for 10 days before surgery. You can take Tylenol for pain. If you are taking herbal supplements, please stop 10 days before your procedure.

Do not eat meals heavy in garlic or drink alcohol for 48 hours before your surgery. If you get sick the week before surgery, please call our office so to reschedule your surgery if required. If it is after hours, you may contact us online.

You must have an empty stomach to have general anesthesia. You may not have anything to eat or drink after midnight the night before UNLESS:

  • Your surgery is after 12 PM – then you may have up to 8 ounces of water 3 hours before your scheduled procedure.
  • You are instructed to take certain medication by the office on the day of surgery. Then a sip of water is allowed.

You will receive a call from the hospital or office the day before surgery to confirm the time for surgery. You should plan to be there 1.5 to 2 hours before the scheduled operative time. If you do not hear from our office or the facility by 3 PM, please call on your own.
