About 0N5B0ZZ
0N5B0ZZ is the ICD-10-PCS code for a destruction procedure on the nasal bone using an open approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.
In plain terms, this corresponds to local excision or destruction of other lesion of nose, the ICD-9-CM procedure title it maps to (21.32).
For a different body part, codes include 0N500ZZ (skull), 0N510ZZ (frontal bone), 0N530ZZ (right parietal bone), 0N540ZZ (left parietal bone), 0N550ZZ (right temporal bone), 0N560ZZ (left temporal bone) and 16 more.
The same procedure with a different approach is coded 0N5B3ZZ (percutaneous) and 0N5B4ZZ (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 495 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur with MCC), DRG 496 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur with CC) and DRG 497 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R.
