About 0NSX0ZZ
0NSX0ZZ is the ICD-10-PCS code for a reposition procedure on the hyoid bone using an open 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 other open reduction of facial fracture, the ICD-9-CM procedure title it maps to (76.79).
For a different body part, codes include 0NS00ZZ (skull), 0NS10ZZ (frontal bone), 0NS30ZZ (right parietal bone), 0NS40ZZ (left parietal bone), 0NS50ZZ (right temporal bone), 0NS60ZZ (left temporal bone) and 16 more.
The same procedure with a different approach is coded 0NSX3ZZ (percutaneous), 0NSX4ZZ (percutaneous endoscopic) and 0NSXXZZ (external).
With a different device, use 0NSX04Z (internal fixation device).
It is an operating-room procedure in the MS-DRG logic for DRG 113 (Orbital Procedures with CC/MCC), DRG 114 (Orbital Procedures without CC/MCC), DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC), DRG 145 (Other Ear, Nose, Mouth and Throat O.R.
