Before your visit

Our Administrative Expert will work with you to set up your appointments in GI and help with any questions or requests you may have in planning your visit to Tufts MC.

The first two steps are as follows:

  1. Fill out the patient intake form.
  2. Email any relevant medical records (translated into English) to GIinternational@tuftsmedicalcenter.org or fax to 617-636-9292 (subject: International Patient).

A Tufts MC gastroenterology specialist reviews your records upon receipt and then prepares a plan of action for your care.

Please see our Patient Accommodations Guide for information on local hotels — and contact us if you need any assistance.

During your visit

Please plan to arrive at our clinic 15–20 minutes before your first appointment. If you specify on the patient intake form that you require language assistance, an interpreter will be available.

Before you leave our clinic, we provide you with a summary of care, which includes the treatment plan, medication lists and details on any upcoming appointments. Our team can also help with tasks such as admitting you to Tufts MC for inpatient care or scheduling follow-up visits at our clinic or elsewhere in the hospital (if needed and in accordance with your travel plans).

After your initial consultation, if your Tufts MC gastroenterologist recommends additional services, we will give you an updated estimated cost.

After your visit

At your request, following every appointment, we will communicate your results, diagnosis and treatment plan to your doctor back home — and we can answer any questions that he or she has.

If you need help with billing-related questions, refilling prescriptions, addressing prior authorizations or any other issue, we will work with you to accommodate these requests. You can always count on our team for a prompt response.
