About 0NWB07Z

0NWB07Z is the ICD-10-PCS code for a revision procedure on the nasal bone using an open approach with autologous 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 incision of nose, the ICD-9-CM procedure title it maps to (21.1).

For a different body part, codes include 0NW007Z (skull) and 0NWW07Z (facial bone).

The same procedure with a different approach is coded 0NWB37Z (percutaneous), 0NWB47Z (percutaneous endoscopic) and 0NWBX7Z (external).

With a different device, use 0NWB00Z (drainage device), 0NWB04Z (internal fixation device), 0NWB05Z (external fixation device), 0NWB0JZ (synthetic substitute), 0NWB0KZ (nonautologous tissue substitute) and 0NWB0MZ (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.
