About 0F198Z3

0F198Z3 is the ICD-10-PCS code for a bypass procedure on the common bile duct using a via natural or artificial opening endoscopic approach (qualifier: duodenum). In ICD-10-PCS, bypass means altering the route of passage of the contents of a tubular body part.

The same procedure with a different approach is coded 0F190Z3 (open) and 0F194Z3 (percutaneous endoscopic).

With a different device, use 0F198D3 (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.
