About 0NWWX5Z

0NWWX5Z is the ICD-10-PCS code for a revision procedure on the facial bone using an external approach with external fixation 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.

For a different body part, codes include 0NW0X5Z (skull) and 0NWBX5Z (nasal bone).

The same procedure with a different approach is coded 0NWW05Z (open), 0NWW35Z (percutaneous) and 0NWW45Z (percutaneous endoscopic).

With a different device, use 0NWWX0Z (drainage device), 0NWWX4Z (internal fixation device), 0NWWX7Z (autologous tissue substitute), 0NWWXJZ (synthetic substitute), 0NWWXKZ (nonautologous tissue substitute) and 0NWWXMZ (bone growth stimulator).

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 FY2025, effective October 1, 2024.
