About 0D9N0ZZ

0D9N0ZZ is the ICD-10-PCS code for a drainage procedure on the sigmoid colon using an open approach. 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 large intestine, the ICD-9-CM procedure title it maps to (45.03).

For a different body part, codes include 0D910ZZ (esophagus, upper), 0D920ZZ (esophagus, middle), 0D930ZZ (esophagus, lower), 0D940ZZ (esophagogastric junction), 0D950ZZ (esophagus), 0D960ZZ (stomach) and 20 more.

The same procedure with a different approach is coded 0D9N3ZZ (percutaneous), 0D9N4ZZ (percutaneous endoscopic), 0D9N7ZZ (via natural or artificial opening) and 0D9N8ZZ (via natural or artificial opening endoscopic).

With a different device, use 0D9N00Z (drainage device).

It is an operating-room procedure in the MS-DRG logic for DRG 344 (Minor Small and Large Bowel Procedures with MCC), DRG 345 (Minor Small and Large Bowel Procedures with CC), DRG 346 (Minor Small and Large Bowel Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Minor Small and Large Bowel Procedures” and “Other O.R. Procedures for Injuries”.

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