About 0NWB4JZ

0NWB4JZ is the ICD-10-PCS code for a revision procedure on the nasal bone using a percutaneous endoscopic approach with synthetic 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 incision of nose, the ICD-9-CM procedure title it maps to (21.1).

For a different body part, codes include 0NW04JZ (skull) and 0NWW4JZ (facial bone).

The same procedure with a different approach is coded 0NWB0JZ (open), 0NWB3JZ (percutaneous) and 0NWBXJZ (external).

With a different device, use 0NWB40Z (drainage device), 0NWB44Z (internal fixation device), 0NWB45Z (external fixation device), 0NWB47Z (autologous tissue substitute), 0NWB4KZ (nonautologous tissue substitute) and 0NWB4MZ (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.
