About 0WPHX0Z

0WPHX0Z is the ICD-10-PCS code for a removal procedure on the retroperitoneum using an external approach with drainage device. In ICD-10-PCS, removal means taking out or off a device from a body part.

In plain terms, this corresponds to removal of retroperitoneal drainage device, the ICD-9-CM procedure title it maps to (97.81).

For a different body part, codes include 0WP0X0Z (head), 0WP1X0Z (cranial cavity), 0WP2X0Z (face), 0WP4X0Z (upper jaw), 0WP5X0Z (lower jaw), 0WP6X0Z (neck) and 12 more.

The same procedure with a different approach is coded 0WPH00Z (open), 0WPH30Z (percutaneous) and 0WPH40Z (percutaneous endoscopic).

With a different device, use 0WPHX1Z (radioactive element) and 0WPHX3Z (infusion 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.
