About 0NQQ4ZZ

0NQQ4ZZ is the ICD-10-PCS code for a repair procedure on the left orbit using a percutaneous endoscopic approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.

The same procedure with a different approach is coded 0NQQ0ZZ (open), 0NQQ3ZZ (percutaneous) and 0NQQXZZ (external).
