About 0F970ZZ

0F970ZZ is the ICD-10-PCS code for a drainage procedure on the hepatic duct, common using an open approach. 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 0F900ZZ (liver), 0F910ZZ (liver, right lobe), 0F920ZZ (liver, left lobe), 0F940ZZ (gallbladder), 0F950ZZ (right hepatic duct), 0F960ZZ (left hepatic duct) and 6 more.

The same procedure with a different approach is coded 0F973ZZ (percutaneous), 0F974ZZ (percutaneous endoscopic), 0F977ZZ (via natural or artificial opening) and 0F978ZZ (via natural or artificial opening endoscopic).

With a different device, use 0F9700Z (drainage 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 was added in FY2018, effective October 1, 2017.
