About 0FQC4ZZ

0FQC4ZZ is the ICD-10-PCS code for a repair procedure on the ampulla of vater using a percutaneous endoscopic approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.

In plain terms, this corresponds to pancreatic sphincteroplasty, the ICD-9-CM procedure title it maps to (51.83).

For a different body part, codes include 0FQ04ZZ (liver), 0FQ14ZZ (liver, right lobe), 0FQ24ZZ (liver, left lobe), 0FQ44ZZ (gallbladder), 0FQ54ZZ (right hepatic duct), 0FQ64ZZ (left hepatic duct) and 6 more.

The same procedure with a different approach is coded 0FQC0ZZ (open), 0FQC3ZZ (percutaneous), 0FQC7ZZ (via natural or artificial opening) and 0FQC8ZZ (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 326 (Stomach, Esophageal and Duodenal Procedures with MCC), DRG 327 (Stomach, Esophageal and Duodenal Procedures with CC), DRG 328 (Stomach, Esophageal and Duodenal Procedures without CC/MCC), DRG 405 (Pancreas, Liver and Shunt Procedures with MCC), DRG 406 (Pancreas, Liver and Shunt Procedures with CC) and DRG 407 (Pancreas, Liver and Shunt Procedures without CC/MCC), under the surgical categories “Stomach, Esophageal and Duodenal Procedures”, “Pancreas, Liver and Shunt Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
