About 0F770DZ

0F770DZ is the ICD-10-PCS code for a dilation procedure on the hepatic duct, common using an open approach with intraluminal device. In ICD-10-PCS, dilation means expanding an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to repair of other bile ducts, the ICD-9-CM procedure title it maps to (51.79).

For a different body part, codes include 0F750DZ (right hepatic duct), 0F760DZ (left hepatic duct), 0F780DZ (cystic duct), 0F790DZ (common bile duct), 0F7C0DZ (ampulla of vater), 0F7D0DZ (pancreatic duct) and 1 more.

The same procedure with a different approach is coded 0F773DZ (percutaneous), 0F774DZ (percutaneous endoscopic), 0F777DZ (via natural or artificial opening) and 0F778DZ (via natural or artificial opening endoscopic).

With a different device, use 0F770ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 408 (Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E. with MCC), DRG 409 (Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E. with CC), DRG 410 (Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E. without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E.”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

It was added in FY2018, effective October 1, 2017.
