About 0NSB0ZZ

0NSB0ZZ is the ICD-10-PCS code for a reposition procedure on the nasal 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 open reduction of nasal fracture, the ICD-9-CM procedure title it maps to (21.72).

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 0NSB3ZZ (percutaneous), 0NSB4ZZ (percutaneous endoscopic) and 0NSBXZZ (external).

With a different device, use 0NSB04Z (internal fixation device).

It is an operating-room procedure in the MS-DRG logic for 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), DRG 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), DRG 516 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with CC) and DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures without CC/MCC), under the surgical categories “Major Head and Neck Procedures”, “Other Musculoskeletal System and Connective Tissue O.R. Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures” and 2 more.

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