About 0WWD40Z

0WWD40Z is the ICD-10-PCS code for a revision procedure on the pericardial cavity using a percutaneous endoscopic approach with drainage device. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

In plain terms, this corresponds to Pericardiotomy, the ICD-9-CM procedure title it maps to (37.12).

For a different body part, codes include 0WW040Z (head), 0WW140Z (cranial cavity), 0WW240Z (face), 0WW440Z (upper jaw), 0WW540Z (lower jaw), 0WW640Z (neck) and 12 more.

The same procedure with a different approach is coded 0WWD00Z (open), 0WWD30Z (percutaneous) and 0WWDX0Z (external).

With a different device, use 0WWD41Z (radioactive element), 0WWD43Z (infusion device) and 0WWD4YZ (other device).

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. Procedures” and 3 more.

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