About 0D990ZX

0D990ZX is the ICD-10-PCS code for a drainage procedure on the duodenum 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 small intestine, the ICD-9-CM procedure title it maps to (45.15).

For a different body part, codes include 0D910ZX (esophagus, upper), 0D920ZX (esophagus, middle), 0D930ZX (esophagus, lower), 0D940ZX (esophagogastric junction), 0D950ZX (esophagus), 0D960ZX (stomach) and 20 more.

The same procedure with a different approach is coded 0D993ZX (percutaneous), 0D994ZX (percutaneous endoscopic), 0D997ZX (via natural or artificial opening) and 0D998ZX (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 344 (Minor Small and Large Bowel Procedures with MCC), DRG 345 (Minor Small and Large Bowel Procedures with CC) and DRG 346 (Minor Small and Large Bowel Procedures without CC/MCC), under the surgical category “Minor Small and Large Bowel Procedures”.

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