About 0NHB34Z
0NHB34Z is the ICD-10-PCS code for a insertion procedure on the nasal bone using a percutaneous approach with internal fixation device. 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 0NH034Z (skull), 0NH134Z (frontal bone), 0NH334Z (right parietal bone), 0NH434Z (left parietal bone), 0NH534Z (right temporal bone), 0NH634Z (left temporal bone) and 16 more.
The same procedure with a different approach is coded 0NHB04Z (open) and 0NHB44Z (percutaneous endoscopic).
With a different device, use 0NHB3MZ (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.
