About 0F978ZX

0F978ZX is the ICD-10-PCS code for a drainage procedure on the hepatic duct, common using a via natural or artificial opening endoscopic approach (qualifier: diagnostic). 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 closed [endoscopic] biopsy of biliary duct or sphincter of Oddi, the ICD-9-CM procedure title it maps to (51.14).

For a different body part, codes include 0F948ZX (gallbladder), 0F958ZX (right hepatic duct), 0F968ZX (left hepatic duct), 0F988ZX (cystic duct), 0F998ZX (common bile duct), 0F9C8ZX (ampulla of vater) and 3 more.

The same procedure with a different approach is coded 0F970ZX (open), 0F973ZX (percutaneous), 0F974ZX (percutaneous endoscopic) and 0F977ZX (via natural or artificial opening).

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.
