About 0F978ZZ
0F978ZZ is the ICD-10-PCS code for a drainage procedure on the hepatic duct, common using a via natural or artificial opening endoscopic 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 endoscopic dilation of ampulla and biliary duct, the ICD-9-CM procedure title it maps to (51.84).
For a different body part, codes include 0F948ZZ (gallbladder), 0F958ZZ (right hepatic duct), 0F968ZZ (left hepatic duct), 0F988ZZ (cystic duct), 0F998ZZ (common bile duct), 0F9C8ZZ (ampulla of vater) and 3 more.
The same procedure with a different approach is coded 0F970ZZ (open), 0F973ZZ (percutaneous), 0F974ZZ (percutaneous endoscopic) and 0F977ZZ (via natural or artificial opening).
With a different device, use 0F9780Z (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.
