We’re happy to share that Madison Medical Affiliates is once again in-network with all UnitedHealthcare insurance plans, effective October 1, 2025.
Ascension Wisconsin and UnitedHealthcare have finalized a new agreement that ensures continued access to in-network care for all UHC Commercial, Medicare, and Medicaid members. Any services received between October 1–13 will also be processed at in-network rates.
We are deeply grateful for your patience and understanding during this transition — and most of all, for the trust you place in us. It’s a privilege to care for you and your family, and we’re thrilled to welcome our UnitedHealthcare patients back with open arms.
As we work through this transition, please be patient with our team — we expect higher-than-usual call volumes over the next few days and will do our best to respond as quickly as possible.
Gastroenterology is a subspecialty of Internal Medicine involving disorders of the esophagus, stomach, small intestine, colon, liver, pancreas, and gall bladder.
Patients with a variety of digestive complaints or problems – abdominal pain, bleeding, heartburn, ulcer disease, hepatitis, colon polyps and cancer, diarrhea or constipation, gallstones, pancreatitis - will often see a gastroenterologist for evaluation and treatment.
Fasting is usually required for at least six hours prior to an endoscopy. Evaluation of the large intestine (sigmoidoscopy or colonoscopy) will require additional preparation. Patients are sedated with intravenous medications and usually have little or no recollection of the procedure. After recovery, the patient will require a drive home. Immediate resumption of a regular diet is the rule.

Mild gas pains are often present after the procedure, but will resolve quickly. More serious complications including bleeding or perforation are extremely rare.
