Ask a question

Intrahepatic choledochoenterostomy is a complex surgical procedure involving the creation of a connection (anastomosis) between an intrahepatic bile duct (located above the common hepatic duct bifurcation) and a segment of the small intestine (enterostomy). This operation serves to bypass biliary obstructions that are situated high in the biliary tree, restoring the flow of bile into the digestive tract. The service is billable by the surgeon (S285A), an assistant (S285B), and an anaesthetist (S285C). The fee for the surgeon (suffix A) is a flat rate. The fees for the assistant (suffix B) and anaesthetist (suffix C) are calculated based on a system of basic and time units. For an assistant, the service includes 9 basic units plus time units. For an anaesthetist, the service includes 12 basic units plus time units. Refer to the Surgical Assistants' Services (:-) and Anaesthesiologists' Services (:-) sections of the General Preamble for detailed time unit calculations.
