About 0F180Z4

0F180Z4 is the ICD-10-PCS code for a bypass procedure on the cystic duct using an open approach (qualifier: stomach). 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 0F140Z4 (gallbladder), 0F150Z4 (right hepatic duct), 0F160Z4 (left hepatic duct), 0F170Z4 (hepatic duct, common), 0F190Z4 (common bile duct) and 0F1D0Z4 (pancreatic duct).

The same procedure with a different approach is coded 0F184Z4 (percutaneous endoscopic).

With a different device, use 0F180D4 (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 has been valid since ICD-10-PCS took effect on October 1, 2015.
