About 0QNB4ZZ
0QNB4ZZ is the ICD-10-PCS code for a release procedure on the right lower femur using a percutaneous endoscopic approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

The same procedure with a different approach is coded 0QNB0ZZ (open) and 0QNB3ZZ (percutaneous).
