About 0F170ZB

0F170ZB is the ICD-10-PCS code for a bypass procedure on the hepatic duct, common using an open approach (qualifier: small intestine). In ICD-10-PCS, bypass means altering the route of passage of the contents of a tubular body part.

In plain terms, this corresponds to anastomosis of hepatic duct to gastrointestinal tract, the ICD-9-CM procedure title it maps to (51.37).

For a different body part, codes include 0F140ZB (gallbladder), 0F150ZB (right hepatic duct), 0F160ZB (left hepatic duct), 0F180ZB (cystic duct), 0F190ZB (common bile duct), 0F1D0ZB (pancreatic duct) and 2 more.

The same procedure with a different approach is coded 0F174ZB (percutaneous endoscopic).

With a different device, use 0F170DB (intraluminal device).

It is an operating-room procedure in the MS-DRG logic for DRG 356 (Other Digestive System O.R. Procedures with MCC), DRG 357 (Other Digestive System O.R. Procedures with CC), DRG 358 (Other Digestive System O.R. Procedures without CC/MCC), DRG 408 (Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E. with MCC), DRG 409 (Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E. with CC) and DRG 410 (Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E. without CC/MCC), under the surgical categories “Other Digestive System O.R. Procedures”, “Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E.”, “Lymphoma and Leukemia with Major O.R. Procedures” and 3 more.

It was added in FY2018, effective October 1, 2017.
