About 0QNH0ZZ

0QNH0ZZ is the ICD-10-PCS code for a release procedure on the left tibia 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 repair or plastic operations on bone, tibia and fibula, the ICD-9-CM procedure title it maps to (78.47).

For a different body part, codes include 0QN00ZZ (lumbar vertebra), 0QN10ZZ (sacrum), 0QN20ZZ (right pelvic bone), 0QN30ZZ (left pelvic bone), 0QN40ZZ (right acetabulum), 0QN50ZZ (left acetabulum) and 18 more.

The same procedure with a different approach is coded 0QNH3ZZ (percutaneous) and 0QNH4ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 492 (Lower Extremity and Humerus Procedures Except Hip, Foot and Femur with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 493 (Lower Extremity and Humerus Procedures Except Hip, Foot and Femur with CC), DRG 494 (Lower Extremity and Humerus Procedures Except Hip, Foot and Femur 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 “Lower Extremity and Humerus Procedures Except Hip, Foot and Femur”, “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.
