Schedule a Video Visit with Your Doctor

Many of our doctors offer video visits, so you can see a doctor from your mobile device instead of an in-person appointment. Log into the NYU Langone Health app to schedule a video visit with a member of your care team, or select the video visit option when you schedule with a new doctor. Learn more about video visits.
