About 0F9770Z

0F9770Z is the ICD-10-PCS code for a drainage procedure on the hepatic duct, common 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), 0F9670Z (left hepatic duct), 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 0F9700Z (open), 0F9730Z (percutaneous), 0F9740Z (percutaneous endoscopic) and 0F9780Z (via natural or artificial opening endoscopic).

With a different device, use 0F977ZZ (no device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It was added in FY2018, effective October 1, 2017.
