Listings come from the CMS NPPES NPI Registry, the public federal record of licensed providers, checked October 2026. Being listed is not a recommendation or an endorsement, and we do not receive anything from these doctors. Call the office to confirm insurance, availability and that they are accepting new patients. In an emergency, call 911.
After your visit

Emerge Care, free to download on iPhone, is built for exactly that: tell it how you feel in your own words, get plain answers with the source behind every fact, and walk into your next gastroenterologist appointment in Indiana with a one-page summary and your questions ready.
Emerge Care never diagnoses or replaces your doctor.
