About 0D168Z9

0D168Z9 is the ICD-10-PCS code for a bypass procedure on the stomach using a via natural or artificial opening endoscopic approach (qualifier: duodenum). In ICD-10-PCS, bypass means altering the route of passage of the contents of a tubular body part.

In plain terms, this corresponds to other gastroenterostomy without gastrectomy, the ICD-9-CM procedure title it maps to (44.39).

For a different body part, codes include 0D118Z9 (esophagus, upper), 0D128Z9 (esophagus, middle), 0D138Z9 (esophagus, lower), 0D158Z9 (esophagus) and 0D198Z9 (duodenum).

The same procedure with a different approach is coded 0D160Z9 (open) and 0D164Z9 (percutaneous endoscopic).

With a different device, use 0D16879 (autologous tissue substitute), 0D168J9 (synthetic substitute) and 0D168K9 (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 361 (Other Circulatory System O.R. Procedures with MCC), DRG 362 (Other Circulatory System O.R. Procedures without MCC), 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) and DRG 423 (Other Hepatobiliary or Pancreas O.R. Procedures with MCC), under the surgical categories “Other Circulatory System O.R. Procedures”, “Stomach, Esophageal and Duodenal Procedures”, “Other Hepatobiliary or Pancreas O.R. Procedures” and 3 more.

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