About 0NW0X3Z

0NW0X3Z is the ICD-10-PCS code for a revision procedure on the skull using an external 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.

The same procedure with a different approach is coded 0NW003Z (open), 0NW033Z (percutaneous) and 0NW043Z (percutaneous endoscopic).

With a different device, use 0NW0X0Z (drainage device), 0NW0X4Z (internal fixation device), 0NW0X5Z (external fixation device), 0NW0X7Z (autologous tissue substitute), 0NW0XJZ (synthetic substitute), 0NW0XKZ (nonautologous tissue substitute) and 2 more.

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

It was added in FY2023, effective October 1, 2022.
