About 0NHT34Z

0NHT34Z is the ICD-10-PCS code for a insertion procedure on the right mandible 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 other incision of facial bone, the ICD-9-CM procedure title it maps to (76.09).

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 0NHT04Z (open) and 0NHT44Z (percutaneous endoscopic).

With a different device, use 0NHT35Z (external fixation device).

It is an operating-room procedure in the MS-DRG logic for DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC) and DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), under the surgical category “Other Ear, Nose, Mouth and Throat O.R. Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
