Our Oklahoma City listings cover central Oklahoma: Oklahoma County, Cleveland County, Canadian County, Pottawatomie County, Grady County and McClain County. That includes Edmond to the north, Norman and Moore to the south and Shawnee to the east.
Specialist care here runs mainly through INTEGRIS Health, OU Health and the University of Oklahoma's medical school, SSM Health, Mercy and Norman Regional. Oklahoma Heart Hospital also appears in the listings. For mental health, the state runs Griffin Memorial Hospital in Norman, and Red Rock Behavioral Health Services, NorthCare and Hope Community Services provide community care.
Most listings are in Oklahoma City itself. Norman has the second-largest group, largely because of its psychiatry listings. Edmond, Moore and Midwest City have smaller groups. If you live in Canadian or Grady County, check Yukon or Chickasha before driving into the city.
Liver specialists in Oklahoma are few, and the ones in our Oklahoma City listings all practice in the city itself. If you can't get in soon, a gastroenterologist can often manage liver disease and refer you on. Ask your primary care doctor which option fits your condition.
A hepatologist is a doctor who focuses on the liver, gallbladder and bile ducts. People see one for hepatitis B or C, fatty liver disease, cirrhosis, autoimmune liver disease, primary biliary cholangitis, liver cancer and abnormal liver tests [2]. Most get a referral from a primary care doctor or a gastroenterologist.
Know that many GI doctors treat the liver. Hepatology is part of gastroenterology. Most hepatologists trained first as gastroenterologists, and many general GI doctors manage common liver problems such as fatty liver disease and hepatitis C. That's why some doctors in this directory are also listed as gastroenterologists. If your liver problem is mild or stable, a GI doctor may be all you need.
Start with the kind of liver care you need.
Check credentials. The American Board of Internal Medicine certifies doctors in gastroenterology and in transplant hepatology. A doctor must be certified in gastroenterology before taking the transplant hepatology exam. You can look up any doctor's certification for free on the ABIM website [1]. Our listings show the credentials doctors report in the federal NPI registry, but we don't verify board certification.
Ask about transplant ties if your disease is advanced. If you have cirrhosis, ask whether the practice works with a liver transplant center. A transplant starts with a referral to a transplant center, where a team decides if you're a candidate [3]. A practice linked to a center can make that step smoother.
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 [6].
Plan for distance. Liver specialists are fewer than other doctors, and many work at large hospitals. You may need to travel for a first visit. Ask whether follow-up visits can be done by video or with your local doctor.
Know when not to wait. Cirrhosis can cause bleeding from swollen veins in the esophagus or stomach [4]. Vomiting blood or material that looks like coffee grounds, or black, tar-like stool, needs emergency care, not an appointment [5]. Call 911.
A gastroenterologist treats the whole digestive system, including the liver. A hepatologist focuses mainly on the liver, gallbladder and bile ducts. Most hepatologists trained as gastroenterologists first, and many GI doctors treat common liver problems. If you have advanced liver disease or may need a transplant, a hepatologist is usually the right choice.
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. Many liver clinics also ask for a referral and your recent blood tests or scans before they book a first visit, so call ahead and ask.
Expect questions about your symptoms, medications, alcohol use and family history, plus a physical exam. The doctor will review your liver blood tests and may order more labs, an ultrasound or a special scan that measures liver stiffness. Some people need a liver biopsy. Bring your recent test results and a list of your medications.
A transplant hepatologist cares for people with advanced liver disease or liver failure. They help decide whether someone may need a new liver and care for them before and after a transplant. In the U.S., they're certified through the American Board of Internal Medicine, and they must be certified in gastroenterology first.
Look the doctor up on the American Board of Internal Medicine's free "Verify a Physician" tool. It shows whether a doctor is certified in gastroenterology and in transplant hepatology. Our listings show the credentials doctors report to the NPI registry, but we don't verify certification ourselves.
