About 0NNK0ZZ

0NNK0ZZ is the ICD-10-PCS code for a release procedure on the right palatine bone 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 0NNK3ZZ (percutaneous) and 0NNK4ZZ (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 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 “Other Ear, Nose, Mouth and Throat O.R. 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.
