About 0F9C70Z

0F9C70Z is the ICD-10-PCS code for a drainage procedure on the ampulla of vater 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 operations on sphincter of Oddi, the ICD-9-CM procedure title it maps to (51.89).

For a different body part, codes include 0F9570Z (right hepatic duct), 0F9670Z (left hepatic duct), 0F9770Z (hepatic duct, common), 0F9870Z (cystic duct), 0F9970Z (common bile duct), 0F9D70Z (pancreatic duct) and 1 more.

The same procedure with a different approach is coded 0F9C00Z (open), 0F9C30Z (percutaneous), 0F9C40Z (percutaneous endoscopic) and 0F9C80Z (via natural or artificial opening endoscopic).

With a different device, use 0F9C7ZZ (no 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 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E.”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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