About 0QSF45Z

0QSF45Z is the ICD-10-PCS code for a reposition procedure on the left patella using a percutaneous endoscopic approach with external 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 application of external fixator device, patella and closed reduction of fracture without internal fixation, tibia and fibula, the ICD-9-CM procedure titles it maps to (78.16 and 79.06).

For a different body part, codes include 0QS245Z (right pelvic bone), 0QS345Z (left pelvic bone), 0QS645Z (right upper femur), 0QS745Z (left upper femur), 0QS845Z (right femoral shaft), 0QS945Z (left femoral shaft) and 13 more.

The same procedure with a different approach is coded 0QSF05Z (open) and 0QSF35Z (percutaneous).

With a different device, use 0QSF44Z (internal fixation device) and 0QSF4ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 400 (Knee Procedures with Principal Diagnosis of Infection), DRG 488 (Knee Procedures without Principal Diagnosis of Infection with CC/MCC), DRG 489 (Knee Procedures without Principal Diagnosis of Infection 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 “Knee Procedures with Principal Diagnosis of Infection”, “Knee Procedures without Principal Diagnosis of Infection”, “Other O.R. Procedures for Injuries” and 1 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
