About 0DH942Z

0DH942Z is the ICD-10-PCS code for a insertion procedure on the duodenum using a percutaneous endoscopic approach with monitoring device. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of 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 0DH542Z (esophagus), 0DH642Z (stomach), 0DH842Z (small intestine), 0DHA42Z (jejunum) and 0DHB42Z (ileum).

The same procedure with a different approach is coded 0DH902Z (open), 0DH932Z (percutaneous), 0DH972Z (via natural or artificial opening) and 0DH982Z (via natural or artificial opening endoscopic).

With a different device, use 0DH941Z (radioactive element), 0DH943Z (infusion device), 0DH94DZ (intraluminal device) and 0DH94UZ (feeding 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. Procedures with MCC), DRG 424 (Other Hepatobiliary or Pancreas O.R. Procedures with CC) and DRG 425 (Other Hepatobiliary or Pancreas O.R. Procedures without CC/MCC), under the surgical categories “Stomach, Esophageal and Duodenal Procedures”, “Other Hepatobiliary or Pancreas O.R. Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

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