About 0NCG0ZZ

0NCG0ZZ is the ICD-10-PCS code for a extirpation procedure on the left ethmoid bone using an open approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.

In plain terms, this corresponds to other incision of facial bone, the ICD-9-CM procedure title it maps to (76.09).

For a different body part, codes include 0NC10ZZ (frontal bone), 0NC30ZZ (right parietal bone), 0NC40ZZ (left parietal bone), 0NC50ZZ (right temporal bone), 0NC60ZZ (left temporal bone), 0NC70ZZ (occipital bone) and 15 more.

The same procedure with a different approach is coded 0NCG3ZZ (percutaneous) and 0NCG4ZZ (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) and DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), under the surgical category “Other Ear, Nose, Mouth and Throat O.R. Procedures”.

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