About 0DT20ZZ

0DT20ZZ is the ICD-10-PCS code for a resection procedure on the esophagus, middle 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 partial esophagectomy, the ICD-9-CM procedure title it maps to (42.41).

For a different body part, codes include 0DT10ZZ (esophagus, upper), 0DT30ZZ (esophagus, lower), 0DT40ZZ (esophagogastric junction), 0DT50ZZ (esophagus), 0DT60ZZ (stomach), 0DT70ZZ (stomach, pylorus) and 18 more.

The same procedure with a different approach is coded 0DT24ZZ (percutaneous endoscopic), 0DT27ZZ (via natural or artificial opening) and 0DT28ZZ (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 326 (Stomach, Esophageal and Duodenal Procedures with MCC), DRG 327 (Stomach, Esophageal and Duodenal Procedures with CC), DRG 328 (Stomach, Esophageal and Duodenal Procedures without CC/MCC), DRG 820 (Lymphoma and Leukemia with Major O.R. Procedures with MCC), DRG 821 (Lymphoma and Leukemia with Major O.R. Procedures with CC) and DRG 822 (Lymphoma and Leukemia with Major O.R. Procedures without CC/MCC), under the surgical categories “Stomach, Esophageal and Duodenal Procedures”, “Lymphoma and Leukemia with Major O.R. Procedures”, “Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures” and 2 more.

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