About 0NNQ0ZZ

0NNQ0ZZ is the ICD-10-PCS code for a release procedure on the left orbit using an open approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to other facial bone repair, the ICD-9-CM procedure title it maps to (76.69).

For a different body part, codes include 0NN10ZZ (frontal bone), 0NN30ZZ (right parietal bone), 0NN40ZZ (left parietal bone), 0NN50ZZ (right temporal bone), 0NN60ZZ (left temporal bone), 0NN70ZZ (occipital bone) and 15 more.

The same procedure with a different approach is coded 0NNQ3ZZ (percutaneous) and 0NNQ4ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 140 (Major Head and Neck Procedures with MCC), DRG 141 (Major Head and Neck Procedures with CC), DRG 142 (Major Head and Neck Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Major Head and Neck Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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