About 0NWBXKZ

0NWBXKZ is the ICD-10-PCS code for a revision procedure on the nasal bone using an external approach with nonautologous tissue substitute. 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 0NW0XKZ (skull) and 0NWWXKZ (facial bone).

The same procedure with a different approach is coded 0NWB0KZ (open), 0NWB3KZ (percutaneous) and 0NWB4KZ (percutaneous endoscopic).

With a different device, use 0NWBX0Z (drainage device), 0NWBX4Z (internal fixation device), 0NWBX5Z (external fixation device), 0NWBX7Z (autologous tissue substitute), 0NWBXJZ (synthetic substitute) and 0NWBXMZ (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 has been valid since ICD-10-PCS took effect on October 1, 2015.
