In the Detroit area

Our Detroit listings cover southeast Michigan: Oakland County, Wayne County, Washtenaw County, Macomb County, St. Clair County and Monroe County. That stretches from Ann Arbor and Ypsilanti in the west to Port Huron in the northeast and Monroe near the Ohio line.

Ann Arbor and Detroit hold the largest groups of listings, and the suburbs add many more. Southfield, Farmington Hills, Dearborn, Troy, Royal Oak, Livonia, Rochester Hills and Novi all have sizable clusters. On the Macomb County side, look in Clinton Township, Warren, Roseville and Sterling Heights.

Henry Ford, Trinity Health, Beaumont and Wayne Health are among the health system names you'll see, and ProMedica appears around Monroe. Independent groups work alongside them, such as Michigan Heart Group, Huron Gastro and Team Wellness Center.

With this many offices, the drive matters. Check each practice's full address and ask which location you'd actually visit. Larger groups often run offices in several suburbs.

GI listings lean heavily toward Ann Arbor, where the Gastroenterology & Hepatology clinic at Taubman Health Center and Huron Gastro both appear. Elsewhere, try Tri-County Gastroenterology, G.I. Medicine Associates in St. Clair Shores or Oakland Gastroenterology Associates. Monroe has a ProMedica office. Ask where your colonoscopy would be done, since it may not be the office you visit.

How to choose a gastroenterologist

A gastroenterologist, or GI doctor, diagnoses and treats problems of the digestive tract: the esophagus, stomach, intestines, colon, liver, pancreas and gallbladder. People see one for heartburn that won't go away, ongoing belly pain, diarrhea or constipation, bleeding, Crohn's disease or ulcerative colitis, and for colonoscopies.

Start with the kind of care you need. Many GI doctors handle a wide range of problems, but some focus on one area:

  • General gastroenterologists handle most needs: reflux, ulcers, irritable bowel syndrome, screening colonoscopies and follow-up on abnormal tests.
  • Inflammatory bowel disease (IBD) specialists manage Crohn's disease and ulcerative colitis over the long term.
  • Advanced endoscopists do complex scope procedures, such as removing large polyps or treating bile duct and pancreas problems.
  • Hepatologists focus on the liver. Many are gastroenterologists with extra liver training.

If you're not sure, a general gastroenterologist is the right first stop. They'll refer you on if you need a subspecialist.

Check credentials. Board certification in gastroenterology shows a doctor has finished specialty training and passed a certification exam. You can look up any doctor's certification for free on the American Board of Internal Medicine website [1]. Our listings show the credentials doctors report in the federal NPI registry, but we don't verify board certification.

Know if you're due for a colonoscopy. Experts recommend colorectal cancer screening for adults ages 45 to 75 [2]. A colonoscopy is one option. Some people can start with a stool test instead. Ask your primary care doctor which test fits you, and whether your family history means you should start earlier.

Confirm insurance before you book. Practices change the plans they accept, so call the office or check your insurer's directory. HMO plans usually need a referral first. Medicare Part B covers medically necessary specialist visits; you typically pay 20% of the Medicare-approved amount after your deductible [5].

Ask where procedures are done. Colonoscopies and other scopes happen in a hospital or a separate endoscopy center. The location can change what you pay, so ask before you schedule.

Know when not to wait. Vomiting blood or material that looks like coffee grounds, black or tar-like stool, or feeling faint, confused or cold and clammy with belly symptoms need emergency care, not an appointment [4]. Call 911.

Frequently asked questions

Do I need a referral to see a gastroenterologist?

It depends on your insurance. Most HMO plans require a referral from your primary care doctor before they'll cover a specialist visit. PPO plans and traditional Medicare usually don't. Some GI practices also want a referral or recent test results before they book you, especially for a procedure, so call ahead and ask what to bring.

At what age should I get a colonoscopy?

The U.S. Preventive Services Task Force recommends colorectal cancer screening for adults ages 45 to 75. A colonoscopy is one way to screen, and stool tests are another. People with a family history of colon cancer, certain polyps or inflammatory bowel disease may need to start earlier or screen more often. Ask your doctor what's right for you.

Does Medicare cover a screening colonoscopy?

Yes. Medicare Part B covers a screening colonoscopy once every 120 months for most people, or once every 24 months if you're at high risk. There's no minimum age. You pay nothing for the screening if your doctor accepts assignment. If a polyp is removed during the test, you may owe a share of the cost.

What happens at a first GI appointment?

Expect questions about your symptoms, diet, bowel habits, medications and family history, plus a physical exam. The doctor may order blood work, a stool test, imaging or a scope procedure such as an upper endoscopy or colonoscopy. Bring a list of your medications and any recent lab results, scans or procedure reports.

How do I know if a gastroenterologist is board certified?

Look the doctor up on the American Board of Internal Medicine's free "Verify a Physician" tool, which shows whether they're certified in gastroenterology. Our listings show the credentials doctors report to the NPI registry, but we don't verify certification ourselves.
