About 0NSV45Z

0NSV45Z is the ICD-10-PCS code for a reposition procedure on the left mandible using a percutaneous endoscopic approach with external fixation device. 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 0NS045Z (skull), 0NSR45Z (maxilla) and 0NST45Z (right mandible).

The same procedure with a different approach is coded 0NSV05Z (open) and 0NSV35Z (percutaneous).

With a different device, use 0NSV44Z (internal fixation device) and 0NSV4ZZ (no device).

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.
