About 0F174Z7

0F174Z7 is the ICD-10-PCS code for a bypass procedure on the hepatic duct, common using a percutaneous endoscopic approach (qualifier: hepatic duct, caudate). 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 other bile duct anastomosis, the ICD-9-CM procedure title it maps to (51.39).

For a different body part, codes include 0F144Z7 (gallbladder), 0F154Z7 (right hepatic duct), 0F164Z7 (left hepatic duct), 0F184Z7 (cystic duct) and 0F194Z7 (common bile duct).

The same procedure with a different approach is coded 0F170Z7 (open).

With a different device, use 0F174D7 (intraluminal device).

It is an operating-room procedure in the MS-DRG logic for 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), DRG 410 (Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E. without CC/MCC), DRG 820 (Lymphoma and Leukemia with Major O.R. Procedures with MCC), DRG 821 (Lymphoma and Leukemia with Major O.R. Procedures with CC) and DRG 822 (Lymphoma and Leukemia with Major O.R. Procedures without CC/MCC), under the surgical categories “Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E.”, “Lymphoma and Leukemia with Major O.R. Procedures”, “Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures” and 2 more.

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