About 0FL77ZZ
0FL77ZZ is the ICD-10-PCS code for a occlusion procedure on the hepatic duct, common using a via natural or artificial opening approach. In ICD-10-PCS, occlusion means completely closing 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 0FL57ZZ (right hepatic duct), 0FL67ZZ (left hepatic duct), 0FL87ZZ (cystic duct), 0FL97ZZ (common bile duct), 0FLC7ZZ (ampulla of vater), 0FLD7ZZ (pancreatic duct) and 1 more.
The same procedure with a different approach is coded 0FL70ZZ (open), 0FL73ZZ (percutaneous), 0FL74ZZ (percutaneous endoscopic) and 0FL78ZZ (via natural or artificial opening endoscopic).
With a different device, use 0FL77DZ (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.
