About 0QWF05Z

0QWF05Z is the ICD-10-PCS code for a revision procedure on the left patella using an open approach with external fixation device. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

In plain terms, this corresponds to other incision of bone without division, patella, the ICD-9-CM procedure title it maps to (77.16).

For a different body part, codes include 0QW205Z (right pelvic bone), 0QW305Z (left pelvic bone), 0QW605Z (right upper femur), 0QW705Z (left upper femur), 0QW805Z (right femoral shaft), 0QW905Z (left femoral shaft) and 13 more.

The same procedure with a different approach is coded 0QWF35Z (percutaneous), 0QWF45Z (percutaneous endoscopic) and 0QWFX5Z (external).

With a different device, use 0QWF04Z (internal fixation device), 0QWF07Z (autologous tissue substitute), 0QWF0JZ (synthetic substitute) and 0QWF0KZ (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 495 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur with MCC), DRG 496 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur with CC), DRG 497 (Local Excision and Removal of Internal Fixation Devices Except Hip 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 “Local Excision and Removal of Internal Fixation Devices Except Hip 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.
