About 0D9900Z

0D9900Z is the ICD-10-PCS code for a drainage procedure on the duodenum using an open approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to incision of duodenum, the ICD-9-CM procedure title it maps to (45.01).

For a different body part, codes include 0D9100Z (esophagus, upper), 0D9200Z (esophagus, middle), 0D9300Z (esophagus, lower), 0D9400Z (esophagogastric junction), 0D9500Z (esophagus), 0D9600Z (stomach) and 20 more.

The same procedure with a different approach is coded 0D9930Z (percutaneous), 0D9940Z (percutaneous endoscopic), 0D9970Z (via natural or artificial opening) and 0D9980Z (via natural or artificial opening endoscopic).

With a different device, use 0D990ZZ (no 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), DRG 328 (Stomach, Esophageal and Duodenal Procedures without CC/MCC), DRG 423 (Other Hepatobiliary or Pancreas O.R.
