About 0N8Q0ZZ

0N8Q0ZZ is the ICD-10-PCS code for a division procedure on the left orbit using an open approach. In ICD-10-PCS, division means cutting into a body part, without draining fluids and/or gases from the body part, in order to separate or transect a body part.

In plain terms, this corresponds to other orbitotomy, the ICD-9-CM procedure title it maps to (16.09).

For a different body part, codes include 0N800ZZ (skull), 0N810ZZ (frontal bone), 0N830ZZ (right parietal bone), 0N840ZZ (left parietal bone), 0N850ZZ (right temporal bone), 0N860ZZ (left temporal bone) and 16 more.

The same procedure with a different approach is coded 0N8Q3ZZ (percutaneous) and 0N8Q4ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 113 (Orbital Procedures with CC/MCC), DRG 114 (Orbital Procedures without CC/MCC), 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) and DRG 907 (Other O.R. Procedures for Injuries with MCC), under the surgical categories “Orbital Procedures”, “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

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