About 0D9U4ZX

0D9U4ZX is the ICD-10-PCS code for a drainage procedure on the omentum using a percutaneous endoscopic 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 biopsy of peritoneum, the ICD-9-CM procedure title it maps to (54.23).

The same procedure with a different approach is coded 0D9U0ZX (open) and 0D9U3ZX (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 356 (Other Digestive System O.R. Procedures with MCC), DRG 357 (Other Digestive System O.R. Procedures with CC), DRG 358 (Other Digestive System O.R.
