About 0F773ZZ

0F773ZZ is the ICD-10-PCS code for a dilation procedure on the hepatic duct, common using a percutaneous approach. In ICD-10-PCS, dilation means expanding an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to other percutaneous procedures on biliary tract, the ICD-9-CM procedure title it maps to (51.98).

For a different body part, codes include 0F753ZZ (right hepatic duct), 0F763ZZ (left hepatic duct), 0F783ZZ (cystic duct), 0F793ZZ (common bile duct), 0F7C3ZZ (ampulla of vater), 0F7D3ZZ (pancreatic duct) and 1 more.

The same procedure with a different approach is coded 0F770ZZ (open), 0F774ZZ (percutaneous endoscopic), 0F777ZZ (via natural or artificial opening) and 0F778ZZ (via natural or artificial opening endoscopic).

With a different device, use 0F773DZ (intraluminal 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.
