About 0NH005Z
0NH005Z is the ICD-10-PCS code for a insertion procedure on the skull using an open approach with external 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 immobilization, pressure, and attention to wound, the ICD-9-CM procedure title it maps to (93.59).
For a different body part, codes include 0NHR05Z (maxilla), 0NHT05Z (right mandible) and 0NHV05Z (left mandible).
The same procedure with a different approach is coded 0NH035Z (percutaneous) and 0NH045Z (percutaneous endoscopic).
With a different device, use 0NH003Z (infusion device), 0NH004Z (internal fixation device), 0NH00MZ (bone growth stimulator) and 0NH00NZ (neurostimulator generator).
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.
