About 0NSC34Z

0NSC34Z is the ICD-10-PCS code for a reposition procedure on the sphenoid bone using a percutaneous approach with internal 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 other closed reduction of facial fracture, the ICD-9-CM procedure title it maps to (76.78).

For a different body part, codes include 0NS034Z (skull), 0NS134Z (frontal bone), 0NS334Z (right parietal bone), 0NS434Z (left parietal bone), 0NS534Z (right temporal bone), 0NS634Z (left temporal bone) and 16 more.

The same procedure with a different approach is coded 0NSC04Z (open) and 0NSC44Z (percutaneous endoscopic).

With a different device, use 0NSC3ZZ (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.
