About 0PSC04Z

0PSC04Z is the ICD-10-PCS code for a reposition procedure on the right humeral head using an open approach with internal fixation device. In ICD-10-PCS, reposition means moving to its normal location, or other suitable location, all or a portion of a body part.

In plain terms, this corresponds to open reduction of fracture with internal fixation, humerus, the ICD-9-CM procedure title it maps to (79.31).

For a different body part, codes include 0PS004Z (sternum), 0PS104Z (ribs, 1 to 2), 0PS204Z (ribs, 3 or more), 0PS304Z (cervical vertebra), 0PS404Z (thoracic vertebra), 0PS504Z (right scapula) and 20 more.

The same procedure with a different approach is coded 0PSC34Z (percutaneous) and 0PSC44Z (percutaneous endoscopic).

With a different device, use 0PSC05Z (external fixation device), 0PSC06Z (internal fixation device, intramedullary), 0PSC0BZ (external fixation device, monoplanar), 0PSC0CZ (external fixation device, ring), 0PSC0DZ (external fixation device, hybrid) and 0PSC0ZZ (no device).

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.
