About 0NJB0ZZ

0NJB0ZZ is the ICD-10-PCS code for a inspection procedure on the nasal bone using an open approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to other diagnostic procedures on nose, the ICD-9-CM procedure title it maps to (21.29).

For a different body part, codes include 0NJ00ZZ (skull) and 0NJW0ZZ (facial bone).

The same procedure with a different approach is coded 0NJB3ZZ (percutaneous), 0NJB4ZZ (percutaneous endoscopic) and 0NJBXZZ (external).

It is an operating-room procedure in the MS-DRG logic for 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. Procedures without CC/MCC), DRG 477 (Biopsies of Musculoskeletal System and Connective Tissue with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 478 (Biopsies of Musculoskeletal System and Connective Tissue with CC) and DRG 479 (Biopsies of Musculoskeletal System and Connective Tissue without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Biopsies of Musculoskeletal System and Connective Tissue”, “Other O.R. Procedures for Injuries” and 1 more.

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