Weight-Loss Surgery With Duodenal Switch

Illinois rates for HCPCS 43845

A weight-loss operation that both shrinks the stomach and shortens the path food takes through the intestine. Part of the stomach is removed to leave a narrow tube, then the small intestine is divided and rerouted so food and digestive juices only mix along a short final stretch, which limits how many calories are absorbed. The valve at the stomach outlet is kept intact.
