About 0NWB30Z

0NWB30Z is the ICD-10-PCS code for a revision procedure on the nasal bone using a percutaneous approach with drainage 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.

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 0NW030Z (skull) and 0NWW30Z (facial bone).

The same procedure with a different approach is coded 0NWB00Z (open), 0NWB40Z (percutaneous endoscopic) and 0NWBX0Z (external).

With a different device, use 0NWB34Z (internal fixation device), 0NWB35Z (external fixation device), 0NWB37Z (autologous tissue substitute), 0NWB3JZ (synthetic substitute), 0NWB3KZ (nonautologous tissue substitute) and 0NWB3MZ (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.
