About 0NBC3ZX
0NBC3ZX is the ICD-10-PCS code for a excision procedure on the sphenoid bone using a percutaneous approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.
In plain terms, this corresponds to biopsy of facial bone, the ICD-9-CM procedure title it maps to (76.11).
For a different body part, codes include 0NB03ZX (skull), 0NB13ZX (frontal bone), 0NB33ZX (right parietal bone), 0NB43ZX (left parietal bone), 0NB53ZX (right temporal bone), 0NB63ZX (left temporal bone) and 16 more.
The same procedure with a different approach is coded 0NBC0ZX (open) and 0NBC4ZX (percutaneous endoscopic).
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” and “Biopsies of Musculoskeletal System and Connective Tissue”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
