About Gastroenterology Providers
A gastroenterologist is a medical physician who specializes in the diagnosis and treatment of disorders affecting the digestive system, including the esophagus, stomach, intestines, liver, gallbladder, and pancreas. They treat conditions like acid reflux, ulcers, irritable bowel syndrome (IBS), crohn's disease, and liver disease. Gastroenterologists complete medical school, a three-year internal medicine residency, and a three-year gastroenterology fellowship. They perform specialized diagnostic procedures like endoscopies and colonoscopies to detect diseases, providing medical management and preventative care.
An NPI number is a critical identifier for gastroenterologists when submitting billing claims for colonoscopies, endoscopies, and specialist consultations. Insurance plans require the physician's NPI to process payments under digestive health billing codes. The NPI database validates the gastroenterologist's medical credentials, active license, and board certifications. Checking the registry helps clinical billers verify network enrollment, obtain prior authorization for procedures, and ensure that patients receive appropriate coverage for gastrointestinal care.
