About 0DTK0ZZ

0DTK0ZZ is the ICD-10-PCS code for a resection procedure on the ascending colon using an open approach. In ICD-10-PCS, resection means cutting out or off, without replacement, all of a body part.

In plain terms, this corresponds to open and other right hemicolectomy and other and unspecified partial excision of large intestine, the ICD-9-CM procedure titles it maps to (45.73 and 45.79).

For a different body part, codes include 0DT10ZZ (esophagus, upper), 0DT20ZZ (esophagus, middle), 0DT30ZZ (esophagus, lower), 0DT40ZZ (esophagogastric junction), 0DT50ZZ (esophagus), 0DT60ZZ (stomach) and 18 more.

The same procedure with a different approach is coded 0DTK4ZZ (percutaneous endoscopic), 0DTK7ZZ (via natural or artificial opening) and 0DTK8ZZ (via natural or artificial opening endoscopic).

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.
