How to Find a Gastroenterologist Near You

Finding a gastroenterologist is mostly a logistics problem. Whether you should see one is a medical question for you and a healthcare professional. This guide covers the other part: getting from “I need to find a GI specialist” to a booked appointment with someone who fits your plan, your location and your preferences.

What a gastroenterologist is

A gastroenterologist is a physician with dedicated training in managing diseases of the gastrointestinal tract and liver. According to the American College of Gastroenterology, the field covers the esophagus, stomach, small intestine, colon and rectum, pancreas, gallbladder, bile ducts and liver.

The training is long. A gastroenterologist first completes a three-year internal medicine residency, followed by a gastroenterology fellowship that generally lasts two to three years. You'll also see the specialty shortened to “GI”, for gastrointestinal: a GI doctor and a gastroenterologist are the same thing.

Step 1: Find out whether you need a referral

Start with your insurance plan's rules, because they decide what happens next. HealthCare.gov defines a referral as a written order from your primary care doctor to see a specialist, and notes that if your plan requires one and you skip it, the plan may not pay for the services.

• HMO plans often require a referral before you see anyone other than your primary care doctor.
• POS plans require a referral from your primary care doctor to see a specialist.
• PPO plans let you see providers without a referral, and cost less when you stay in network.
• EPO plans cover services only from providers in the plan's network, except in an emergency.

These are the general patterns described by HealthCare.gov. Your own plan documents, or a call to the number on your insurance card, will give you the definitive answer.

Step 2: Build a shortlist

Use more than one source. Each has blind spots, and the overlap between them is a good place to start.

• Your insurer's provider directory. The most direct way to see who is in your plan's network. Search by specialty (gastroenterology) and location.
• Your primary care clinician. If you need a referral anyway, ask who they refer to and why.
• Professional-society locators. The American College of Gastroenterology offers a find-a-gastroenterologist tool.
• Medicare's Care Compare. If you have Medicare, Care Compare lets you look up doctors and clinicians near you.

Step 3: Check credentials

Two independent checks are worth a few minutes each.

• Board certification. Gastroenterology is a subspecialty of internal medicine. You can check a physician's certification with the American Board of Internal Medicine's verification tool or through Certification Matters, run by the American Board of Medical Specialties.
• Medical licence. Physicians are licensed by state medical boards. The Federation of State Medical Boards offers a free lookup at DocInfo.

Step 4: Confirm the insurance details twice

A directory listing is a starting point, not a guarantee. Networks change, and a doctor can be in-network at one office and not at another. Before you book:

1. Call the practice. Give them your exact plan name and network (both are on your insurance card) and ask whether the specific doctor is in-network at the specific location.
2. Call your insurer, or check your member portal, and ask the same question.
3. Write down the date, who you spoke to and any reference number.

If a procedure is likely to be part of your care, ask where it would be performed and whether that facility is in your network too. For the full routine, read How to Check Whether a Doctor Accepts Your Insurance.

Step 5: Compare the practical details

With a verified shortlist, the decision usually comes down to fit.

• Distance and location. Consider where follow-up visits and any procedures would take place, not just the first consultation.
• Visit type. Some practices offer telehealth for consultations and follow-ups. Ask which visits can be done by video.
• Language. Ask whether the doctor or the practice can work in the language you're most comfortable in, and whether interpreter services are available.
• Hospital affiliation. This tells you which hospitals a doctor works with, which matters for both convenience and network coverage.
• Availability. Ask when the next new-patient appointment is, and whether there is a cancellation list.

Step 6: Book, and prepare

When you call to book, have your insurance card and any referral details to hand. Before the visit, the National Institute on Aging suggests making a list of what you want to discuss, putting your most important concerns first, and bringing information about your medications. The Agency for Healthcare Research and Quality publishes questions you can adapt for your own appointment.
