About 0NQT0ZZ

0NQT0ZZ is the ICD-10-PCS code for a repair procedure on the right mandible using an open approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.

In plain terms, this corresponds to Alveoloplasty, open osteoplasty [osteotomy] of mandibular ramus, osteoplasty [osteotomy] of body of mandible and 1 more, the ICD-9-CM procedure titles it maps to (24.5, 76.62, 76.63 and 1 more).
