About 0F977ZZ
0F977ZZ is the ICD-10-PCS code for a drainage procedure on the hepatic duct, common using a via natural or artificial opening 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 0F957ZZ (right hepatic duct), 0F967ZZ (left hepatic duct), 0F987ZZ (cystic duct), 0F997ZZ (common bile duct), 0F9C7ZZ (ampulla of vater), 0F9D7ZZ (pancreatic duct) and 1 more.
The same procedure with a different approach is coded 0F970ZZ (open), 0F973ZZ (percutaneous), 0F974ZZ (percutaneous endoscopic) and 0F978ZZ (via natural or artificial opening endoscopic).
With a different device, use 0F9770Z (drainage 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.
