About 0D940ZX

0D940ZX is the ICD-10-PCS code for a drainage procedure on the esophagogastric junction using an open approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to open biopsy of esophagus, the ICD-9-CM procedure title it maps to (42.25).

For a different body part, codes include 0D910ZX (esophagus, upper), 0D920ZX (esophagus, middle), 0D930ZX (esophagus, lower), 0D950ZX (esophagus), 0D960ZX (stomach), 0D970ZX (stomach, pylorus) and 20 more.

The same procedure with a different approach is coded 0D943ZX (percutaneous), 0D944ZX (percutaneous endoscopic), 0D947ZX (via natural or artificial opening) and 0D948ZX (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” and “Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures”.

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