Appointment Information

Appointments are scheduled upon receipt of a referral from your treating clinician. We will call you to schedule your appointment.


Endoscopy provides upper and lower gastrointestinal endoscopic procedures for Yale Health members and students with Yale Health Hospitalization/Specialty Care coverage. A referral from your primary care provider is required. Patients who require anesthesia services will be referred to Yale-New Haven Hospital.

Procedures are performed under conscious sedation. Recovery time is approximately one hour.

Make arrangements for a family member or friend to pick you up at the Endoscopy Suite after your procedure. The medication given during the procedure may cause drowsiness, making it unsafe for you to drive home or take public transportation alone.

Be sure to follow the instructions we mail to you. Preparation starts the day before your procedure. On the day of your procedure do not eat or drink anything. If you are taking medications, take them with a sip of water unless directed otherwise. Please arrive 30 minutes before your appointment.

If you have pain, bleeding or black stools after your procedure call your primary care provider.

A late cancelation/no show fee will apply if appropriate notice is not provided. See your schedule of benefits on your coverage page for more detail.
