About 0D9U4ZZ
0D9U4ZZ is the ICD-10-PCS code for a drainage procedure on the omentum using a percutaneous endoscopic approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to percutaneous abdominal drainage, the ICD-9-CM procedure title it maps to (54.91).
For a different body part, codes include 0D914ZZ (esophagus, upper), 0D924ZZ (esophagus, middle), 0D934ZZ (esophagus, lower), 0D944ZZ (esophagogastric junction), 0D954ZZ (esophagus), 0D964ZZ (stomach) and 20 more.
The same procedure with a different approach is coded 0D9U0ZZ (open) and 0D9U3ZZ (percutaneous).
With a different device, use 0D9U40Z (drainage device).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It was added in FY2018, effective October 1, 2017.
