About 0NHB3MZ
0NHB3MZ is the ICD-10-PCS code for a insertion procedure on the nasal bone using a percutaneous approach with bone growth stimulator. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of 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 0NH03MZ (skull) and 0NHW3MZ (facial bone).
The same procedure with a different approach is coded 0NHB0MZ (open) and 0NHB4MZ (percutaneous endoscopic).
With a different device, use 0NHB34Z (internal fixation device).
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.
