About 0NQ1XZZ

0NQ1XZZ is the ICD-10-PCS code for a repair procedure on the frontal bone using an external approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.

In plain terms, this corresponds to other cranial osteoplasty, the ICD-9-CM procedure title it maps to (02.06).

For a different body part, codes include 0NQ0XZZ (skull), 0NQ3XZZ (right parietal bone), 0NQ4XZZ (left parietal bone), 0NQ5XZZ (right temporal bone), 0NQ6XZZ (left temporal bone), 0NQ7XZZ (occipital bone) and 16 more.

The same procedure with a different approach is coded 0NQ10ZZ (open), 0NQ13ZZ (percutaneous) and 0NQ14ZZ (percutaneous endoscopic).

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.
