About 0D594Z3

0D594Z3 is the ICD-10-PCS code for a destruction procedure on the duodenum using a percutaneous endoscopic approach (qualifier: laser interstitial thermal therapy). In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.

For a different body part, codes include 0D514Z3 (esophagus, upper), 0D524Z3 (esophagus, middle), 0D534Z3 (esophagus, lower), 0D544Z3 (esophagogastric junction), 0D554Z3 (esophagus), 0D564Z3 (stomach) and 16 more.

The same procedure with a different approach is coded 0D590Z3 (open) and 0D593Z3 (percutaneous).

It is a non-O.R. procedure that is part of 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.
