About 0WWMXYZ

0WWMXYZ is the ICD-10-PCS code for a revision procedure on the perineum, male using an external approach with other 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 miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).

For a different body part, codes include 0WW0XYZ (head), 0WW1XYZ (cranial cavity), 0WW2XYZ (face), 0WW4XYZ (upper jaw), 0WW5XYZ (lower jaw), 0WW6XYZ (neck) and 15 more.

The same procedure with a different approach is coded 0WWM0YZ (open), 0WWM3YZ (percutaneous) and 0WWM4YZ (percutaneous endoscopic).

With a different device, use 0WWMX0Z (drainage device), 0WWMX1Z (radioactive element), 0WWMX3Z (infusion device), 0WWMX7Z (autologous tissue substitute), 0WWMXJZ (synthetic substitute) and 0WWMXKZ (nonautologous tissue substitute).

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.
