What Does a Gastroenterologist Do?
A gastroenterologist is a medical doctor who treats the digestive system. This includes the stomach, intestines, liver, gallbladder, pancreas, and esophagus. Gastroenterologists diagnose problems, manage treatment plans, and provide procedures such as:
- Endoscopies and colonoscopies
- Tissue sampling and imaging studies
- Medication management and nutritional planning
- Screening and early detection of GI cancers
- Ongoing care for chronic GI and liver conditions
They often coordinate with other specialists to provide complete care when digestive health affects other systems.
Insurance and Coverage for GI Services
Gastroenterology services are often included in most health insurance plans. Coverage depends on your provider, plan type, and the nature of your visit (preventive vs. diagnostic).
- Medicare: Part B typically covers colonoscopies, endoscopies, and follow-up care when medically necessary.
- Medicaid: Coverage varies by state but often includes GI evaluations, especially when symptoms are present.
- Private Insurance: Most plans cover both preventive and medically necessary procedures.
Our staff will assist you in confirming your insurance benefits and helping you understand your options before your visit.
