About 0W9D4ZX

0W9D4ZX is the ICD-10-PCS code for a drainage procedure on the pericardial cavity 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 Pericardiocentesis, the ICD-9-CM procedure title it maps to (37.0).

The same procedure with a different approach is coded 0W9D0ZX (open) and 0W9D3ZX (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC), DRG 165 (Major Chest Procedures without CC/MCC), DRG 270 (Other Major Cardiovascular Procedures with MCC), DRG 271 (Other Major Cardiovascular Procedures with CC) and DRG 272 (Other Major Cardiovascular Procedures without CC/MCC), under the surgical categories “Major Chest Procedures”, “Other Major Cardiovascular Procedures”, “Lymphoma and Leukemia with Major O.R.
