About 0NSTXZZ

0NSTXZZ is the ICD-10-PCS code for a reposition procedure on the right mandible using an external approach. In ICD-10-PCS, reposition means moving to its normal location, or other suitable location, all or a portion of a body part.

In plain terms, this corresponds to closed reduction of mandibular fracture, the ICD-9-CM procedure title it maps to (76.75).

For a different body part, codes include 0NS0XZZ (skull), 0NS1XZZ (frontal bone), 0NS3XZZ (right parietal bone), 0NS4XZZ (left parietal bone), 0NS5XZZ (right temporal bone), 0NS6XZZ (left temporal bone) and 16 more.

The same procedure with a different approach is coded 0NST0ZZ (open), 0NST3ZZ (percutaneous) and 0NST4ZZ (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.
