About 0DTM7ZZ

0DTM7ZZ is the ICD-10-PCS code for a resection procedure on the descending colon using a via natural or artificial opening approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to other and unspecified partial excision of large intestine, the ICD-9-CM procedure title it maps to (45.79).

For a different body part, codes include 0DT17ZZ (esophagus, upper), 0DT27ZZ (esophagus, middle), 0DT37ZZ (esophagus, lower), 0DT47ZZ (esophagogastric junction), 0DT57ZZ (esophagus), 0DT67ZZ (stomach) and 16 more.

The same procedure with a different approach is coded 0DTM0ZZ (open), 0DTM4ZZ (percutaneous endoscopic), 0DTM8ZZ (via natural or artificial opening endoscopic) and 0DTMFZZ (via natural or artificial opening with percutaneous endoscopic assistance).

It is an operating-room procedure in the MS-DRG logic for DRG 361 (Other Circulatory System O.R. Procedures with MCC), DRG 362 (Other Circulatory System O.R. Procedures without MCC), DRG 329 (Major Small and Large Bowel Procedures with MCC), DRG 330 (Major Small and Large Bowel Procedures with CC), DRG 331 (Major Small and Large Bowel Procedures without CC/MCC) and DRG 820 (Lymphoma and Leukemia with Major O.R. Procedures with MCC), under the surgical categories “Other Circulatory System O.R. Procedures”, “Major Small and Large Bowel Procedures”, “Lymphoma and Leukemia with Major O.R. Procedures” and 3 more.

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