About 0DBW0ZZ

0DBW0ZZ is the ICD-10-PCS code for a excision procedure on the peritoneum using an open approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to excision or destruction of peritoneal tissue, the ICD-9-CM procedure title it maps to (54.4).

For a different body part, codes include 0DB10ZZ (esophagus, upper), 0DB20ZZ (esophagus, middle), 0DB30ZZ (esophagus, lower), 0DB40ZZ (esophagogastric junction), 0DB50ZZ (esophagus), 0DB60ZZ (stomach) and 20 more.

The same procedure with a different approach is coded 0DBW3ZZ (percutaneous) and 0DBW4ZZ (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. Procedures with CC) and DRG 425 (Other Hepatobiliary or Pancreas O.R. Procedures without CC/MCC), under the surgical categories “Other Digestive System O.R. Procedures”, “Other Hepatobiliary or Pancreas O.R. Procedures”, “Other Endocrine, Nutritional and Metabolic O.R. Procedures” and 3 more.

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