About 0DT78ZZ

0DT78ZZ is the ICD-10-PCS code for a resection procedure on the stomach, pylorus using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to partial gastrectomy with anastomosis to duodenum, the ICD-9-CM procedure title it maps to (43.6).

For a different body part, codes include 0DT18ZZ (esophagus, upper), 0DT28ZZ (esophagus, middle), 0DT38ZZ (esophagus, lower), 0DT48ZZ (esophagogastric junction), 0DT58ZZ (esophagus), 0DT68ZZ (stomach) and 16 more.

The same procedure with a different approach is coded 0DT70ZZ (open), 0DT74ZZ (percutaneous endoscopic) and 0DT77ZZ (via natural or artificial opening).

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 820 (Lymphoma and Leukemia with Major O.R. Procedures with MCC), under the surgical categories “Other Circulatory System O.R. Procedures”, “Stomach, Esophageal and Duodenal Procedures”, “Lymphoma and Leukemia with Major O.R. Procedures” and 3 more.

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