First Visit

Please bring your insurance card, photo ID, and, if required by your insurance carrier, a referral for services.

If you have a latex allergy, egg allergy, pacemaker, internal defibrillator, artificial heart valve, or joint replacement, please notify your physician when you schedule your procedure.

Stop taking nonsteroidal medication (Motrin, Advil, Ibuprofen, Aleve, etc.) according to your physician’s instructions.

Make sure your physician knows if you are on blood thinners such as Coumadin, Plavix, Xarelto, etc.

Make sure your physician is aware of any previous problems you have had with anesthesia.

You will be asked to arrive 45 minutes earlier than your scheduled procedure time so the staff can prepare you for your procedure. You will also be asked to verify your name and birth date throughout your visit. This practice is for your safety, which is our utmost concern.


You will be called the day before your procedure to provide and verify certain information. This includes expected time of arrival, directions if needed, and a reminder that you must have a responsible driver take you home.

Please see our services page for more information on procedural preparation.

Please refrain from bringing children to the facility if possible.

CDDA accepts most major insurance plans. Copays are due at time of service. It is important to understand the bills you will receive after the procedure. You will receive:

  • A bill from your physician’s office for professional services
  • A bill for anesthesia if you required these services
  • A bill from CDDA for the use of our facility
  • You may also receive a bill for laboratory services if specimens were taken during your procedure.


CDDA is not an emergency treatment facility. In case of emergency, contact your physician or go directly to the closest hospital emergency room. Hospital staff can determine the extent of your problems and contact us. Some problems that require emergency attention include:

  • Fever
  • Pain not managed by prescribed medication
  • Shortness of breath
  • Chest pain
  • Excessive bleeding
