About 0NSQ04Z

0NSQ04Z is the ICD-10-PCS code for a reposition procedure on the left orbit using an open 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 open reduction of facial fracture, the ICD-9-CM procedure title it maps to (76.79).

For a different body part, codes include 0NS004Z (skull), 0NS104Z (frontal bone), 0NS304Z (right parietal bone), 0NS404Z (left parietal bone), 0NS504Z (right temporal bone), 0NS604Z (left temporal bone) and 16 more.

The same procedure with a different approach is coded 0NSQ34Z (percutaneous) and 0NSQ44Z (percutaneous endoscopic).

With a different device, use 0NSQ0ZZ (no 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 140 (Major Head and Neck Procedures with MCC), DRG 141 (Major Head and Neck Procedures with CC), DRG 142 (Major Head and Neck Procedures without CC/MCC) and DRG 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), under the surgical categories “Orbital Procedures”, “Major Head and Neck Procedures”, “Other Musculoskeletal System and Connective Tissue O.R. Procedures” and 2 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
