About 0W3H0ZZ

0W3H0ZZ is the ICD-10-PCS code for a control procedure on the retroperitoneum using an open approach. In ICD-10-PCS, control means stopping, or attempting to stop, postprocedural or other acute bleeding.

In plain terms, this corresponds to Reopening of recent laparotomy site, the ICD-9-CM procedure title it maps to (54.12).

The same procedure with a different approach is coded 0W3H3ZZ (percutaneous) and 0W3H4ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 356 (Other Digestive System O.R. Procedures with MCC), DRG 357 (Other Digestive System O.R. Procedures with CC), DRG 358 (Other Digestive System O.R. Procedures without CC/MCC), DRG 423 (Other Hepatobiliary or Pancreas O.R. Procedures with MCC), DRG 424 (Other Hepatobiliary or Pancreas O.R.
