About 0F998ZX

0F998ZX is the ICD-10-PCS code for a drainage procedure on the common bile duct 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), 0F978ZX (hepatic duct, common), 0F988ZX (cystic duct), 0F9C8ZX (ampulla of vater) and 3 more.

The same procedure with a different approach is coded 0F990ZX (open), 0F993ZX (percutaneous), 0F994ZX (percutaneous endoscopic) and 0F997ZX (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 has been valid since ICD-10-PCS took effect on October 1, 2015.
