About 0NQRXZZ

0NQRXZZ is the ICD-10-PCS code for a repair procedure on the maxilla 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 Alveoloplasty and segmental osteoplasty [osteotomy] of maxilla, the ICD-9-CM procedure titles it maps to (24.5 and 76.65).

For a different body part, codes include 0NQ0XZZ (skull), 0NQ1XZZ (frontal bone), 0NQ3XZZ (right parietal bone), 0NQ4XZZ (left parietal bone), 0NQ5XZZ (right temporal bone), 0NQ6XZZ (left temporal bone) and 16 more.

The same procedure with a different approach is coded 0NQR0ZZ (open), 0NQR3ZZ (percutaneous) and 0NQR4ZZ (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.
