FAQ

How can I make an appointment to come to your office?

You can schedule an appointment online or by call our Winchester clinic at (540) 667-1244 or our Purcellville clinic at (540) 441-4900.

How do I know if I need a referral for my office appointment?

Many insurance plans, especially HMO’s, require a referral or written authorization from your Primary Care Physician for each visit. Your PCP should be able to tell you if you need a referral but ultimately it is your responsibility to know if a referral or written authorization is required before each visit and to obtain one.

For further questions or concerns regarding your referral please call our office at (540) 667-1244 and ask for our Authorization Specialist.

Do I need to bring anything to my office appointment?

Yes, please bring your insurance card, co-payment owed, medical records that would pertain to your office appointment, and any current medication list or your medications. If you are a new patient to our facility please print out and bring the Patient Intake Forms along with you to your visit with us to help expedite your visit.

Why can't I drive myself home after my procedure?

Since you will be sedated, you will need to arrange for someone to drive you home after the procedure. If you do not have a driver your procedure will be cancelled. You cannot go home by cab unless you have a responsible party with you.

An item I needed for my procedure prep has been recalled. Where can I find alternate prep instructions?

Up-to-date prep instructions can be found on our website here.

What if I need to cancel my appointment?

Should you wish to cancel your office appointment, please notify us at 540-667-1244 at least 24 hours prior to your scheduled appointment time. Less time than 24 hours’ notice will result in a $50 “no show” fee being billed and due prior to rescheduling another appointment.

If you wish to cancel your out-patient procedure such as a Colonoscopy, UGI Endoscopy, ERCP, etc., please immediately notify us at 540-667-1244. (This number is available after hours for messages.) Failure to notify us of your cancellation 72 hours in advance may result in a charge of $150 to you.

I need an interpreter for my appointment. How does that work?

Some of our providers speak languages in addition to English. However, if your provider is not fluent in your preferred language, we can help. Winchester Gastroenterology Associates offers translation services for over 300 languages through CyraCom, including Spanish and American Sign Language (ASL). The interpreter will join your appointment via video or phone.

Please let the scheduler know when you make your appointment if you will need a translator.

Winchester Gastroenterology offers translation services free of charge as part of our commitment to superior patient care and in compliance with the Americans with Disability Act (ADA).

I'm taking a GLP-1 agnostic for diabetes management or for weight loss. Do I need to follow any special instructions?

What's included in a Clear Liquid Diet?

Do you provide care for patients of all ages?

Does Winchester Gastroenterology use artificial intelligence (AI) for their healthcare delivery?

Yes, we use AI to provide modern, sustainable care. Please download our Notice of Use in AI Technology for more information.
