About 0NWB3MZ

0NWB3MZ is the ICD-10-PCS code for a revision procedure on the nasal bone using a percutaneous approach with bone growth stimulator. 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 incision of nose, the ICD-9-CM procedure title it maps to (21.1).

For a different body part, codes include 0NW03MZ (skull) and 0NWW3MZ (facial bone).

The same procedure with a different approach is coded 0NWB0MZ (open), 0NWB4MZ (percutaneous endoscopic) and 0NWBXMZ (external).

With a different device, use 0NWB30Z (drainage device), 0NWB34Z (internal fixation device), 0NWB35Z (external fixation device), 0NWB37Z (autologous tissue substitute), 0NWB3JZ (synthetic substitute) and 0NWB3KZ (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.
