About 0WW841Z

0WW841Z is the ICD-10-PCS code for a revision procedure on the chest wall using a percutaneous endoscopic approach with radioactive element. 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 incision of chest wall, the ICD-9-CM procedure title it maps to (34.01).

For a different body part, codes include 0WW041Z (head), 0WW141Z (cranial cavity), 0WW241Z (face), 0WW441Z (upper jaw), 0WW541Z (lower jaw), 0WW641Z (neck) and 15 more.

The same procedure with a different approach is coded 0WW801Z (open), 0WW831Z (percutaneous) and 0WW8X1Z (external).

With a different device, use 0WW840Z (drainage device), 0WW843Z (infusion device), 0WW847Z (autologous tissue substitute), 0WW84JZ (synthetic substitute), 0WW84KZ (nonautologous tissue substitute) and 0WW84YZ (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.
