About 0D978ZZ

0D978ZZ is the ICD-10-PCS code for a drainage procedure on the stomach, pylorus using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to Pyloromyotomy, the ICD-9-CM procedure title it maps to (43.3).

For a different body part, codes include 0D918ZZ (esophagus, upper), 0D928ZZ (esophagus, middle), 0D938ZZ (esophagus, lower), 0D948ZZ (esophagogastric junction), 0D958ZZ (esophagus), 0D968ZZ (stomach) and 16 more.

The same procedure with a different approach is coded 0D970ZZ (open), 0D973ZZ (percutaneous), 0D974ZZ (percutaneous endoscopic) and 0D977ZZ (via natural or artificial opening).

With a different device, use 0D9780Z (drainage device).

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) and DRG 328 (Stomach, Esophageal and Duodenal Procedures without CC/MCC), under the surgical category “Stomach, Esophageal and Duodenal Procedures”.

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