About 0NPB3MZ

0NPB3MZ is the ICD-10-PCS code for a removal procedure on the nasal bone using a percutaneous approach with bone growth stimulator. In ICD-10-PCS, removal means taking out or off a device from a body part.

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 0NP03MZ (skull) and 0NPW3MZ (facial bone).

The same procedure with a different approach is coded 0NPB0MZ (open), 0NPB4MZ (percutaneous endoscopic) and 0NPBXMZ (external).

With a different device, use 0NPB30Z (drainage device), 0NPB34Z (internal fixation device), 0NPB35Z (external fixation device), 0NPB37Z (autologous tissue substitute), 0NPB3JZ (synthetic substitute) and 0NPB3KZ (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.
