About 0DTG0ZZ

0DTG0ZZ is the ICD-10-PCS code for a resection procedure on the left large intestine 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 left hemicolectomy, the ICD-9-CM procedure title it maps to (45.75).

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 0DTG4ZZ (percutaneous endoscopic), 0DTG7ZZ (via natural or artificial opening), 0DTG8ZZ (via natural or artificial opening endoscopic) and 0DTGFZZ (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 628 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with MCC or Insertion of Antibiotic-eluting Bone Void Filler), under the surgical categories “Other Circulatory System O.R. Procedures”, “Major Small and Large Bowel Procedures”, “Other Endocrine, Nutritional and Metabolic O.R. Procedures” and 4 more.

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