About 0F9670Z

0F9670Z is the ICD-10-PCS code for a drainage procedure on the left hepatic duct using a via natural or artificial opening approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to other incision of other bile duct, the ICD-9-CM procedure title it maps to (51.59).

For a different body part, codes include 0F9570Z (right hepatic duct), 0F9770Z (hepatic duct, common), 0F9870Z (cystic duct), 0F9970Z (common bile duct), 0F9C70Z (ampulla of vater), 0F9D70Z (pancreatic duct) and 1 more.

The same procedure with a different approach is coded 0F9600Z (open), 0F9630Z (percutaneous), 0F9640Z (percutaneous endoscopic) and 0F9680Z (via natural or artificial opening endoscopic).

With a different device, use 0F967ZZ (no 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.” and “Other O.R. Procedures for Injuries”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
