About 0F9970Z

0F9970Z is the ICD-10-PCS code for a drainage procedure on the common bile 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 insertion of choledochohepatic tube for decompression, the ICD-9-CM procedure title it maps to (51.43).

For a different body part, codes include 0F9570Z (right hepatic duct), 0F9670Z (left hepatic duct), 0F9770Z (hepatic duct, common), 0F9870Z (cystic duct), 0F9C70Z (ampulla of vater), 0F9D70Z (pancreatic duct) and 1 more.

The same procedure with a different approach is coded 0F9900Z (open), 0F9930Z (percutaneous), 0F9940Z (percutaneous endoscopic) and 0F9980Z (via natural or artificial opening endoscopic).

With a different device, use 0F997ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 405 (Pancreas, Liver and Shunt Procedures with MCC), DRG 406 (Pancreas, Liver and Shunt Procedures with CC), DRG 407 (Pancreas, Liver and Shunt Procedures 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 “Pancreas, Liver and Shunt Procedures”, “Lymphoma and Leukemia with Major O.R. Procedures”, “Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures” and 2 more.
