About 0WW940Z

0WW940Z is the ICD-10-PCS code for a revision procedure on the right pleural 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 other incision of pleura, the ICD-9-CM procedure title it maps to (34.09).

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 0WW900Z (open), 0WW930Z (percutaneous) and 0WW9X0Z (external).

With a different device, use 0WW941Z (radioactive element), 0WW943Z (infusion device), 0WW94JZ (synthetic substitute) and 0WW94YZ (other device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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