Gastric Bypass Surgery (Standard Roux-en-Y)

Washington rates for HCPCS 43846

A weight-loss operation for severe obesity in which the surgeon creates a small pouch from the upper stomach and connects it directly to a section of the small intestine, so food bypasses most of the stomach and the first part of the intestine. This reduces how much food can be eaten at one time and how many calories and nutrients the body absorbs. It is the standard version of this operation, using a shorter rerouted segment of intestine than the extended version reserved for the highest-weight patients.
