About 0WW843Z
0WW843Z is the ICD-10-PCS code for a revision procedure on the chest wall using a percutaneous endoscopic approach with infusion 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 incision of chest wall, the ICD-9-CM procedure title it maps to (34.01).
For a different body part, codes include 0WW043Z (head), 0WW143Z (cranial cavity), 0WW243Z (face), 0WW443Z (upper jaw), 0WW543Z (lower jaw), 0WW643Z (neck) and 15 more.
The same procedure with a different approach is coded 0WW803Z (open), 0WW833Z (percutaneous) and 0WW8X3Z (external).
With a different device, use 0WW840Z (drainage device), 0WW841Z (radioactive element), 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.
