About 0F7C4ZZ

0F7C4ZZ is the ICD-10-PCS code for a dilation procedure on the ampulla of vater using a percutaneous endoscopic approach. In ICD-10-PCS, dilation means expanding an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to dilation of sphincter of Oddi, the ICD-9-CM procedure title it maps to (51.81).

For a different body part, codes include 0F754ZZ (right hepatic duct), 0F764ZZ (left hepatic duct), 0F774ZZ (hepatic duct, common), 0F784ZZ (cystic duct), 0F794ZZ (common bile duct), 0F7D4ZZ (pancreatic duct) and 1 more.

The same procedure with a different approach is coded 0F7C0ZZ (open), 0F7C3ZZ (percutaneous), 0F7C7ZZ (via natural or artificial opening) and 0F7C8ZZ (via natural or artificial opening endoscopic).

With a different device, use 0F7C4DZ (intraluminal device).

It is an operating-room procedure in the MS-DRG logic for DRG 356 (Other Digestive System O.R. Procedures with MCC), DRG 357 (Other Digestive System O.R. Procedures with CC), DRG 358 (Other Digestive System O.R. Procedures without CC/MCC), 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) and DRG 410 (Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E. without CC/MCC), under the surgical categories “Other Digestive System O.R. Procedures”, “Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E.”, “Other O.R. Procedures for Injuries” and 1 more.
