About 0QWF4KZ

0QWF4KZ is the ICD-10-PCS code for a revision procedure on the left patella using a percutaneous endoscopic approach with nonautologous tissue substitute. 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 0QW04KZ (lumbar vertebra), 0QW14KZ (sacrum), 0QW24KZ (right pelvic bone), 0QW34KZ (left pelvic bone), 0QW44KZ (right acetabulum), 0QW54KZ (left acetabulum) and 18 more.

The same procedure with a different approach is coded 0QWF0KZ (open), 0QWF3KZ (percutaneous) and 0QWFXKZ (external).

With a different device, use 0QWF44Z (internal fixation device), 0QWF45Z (external fixation device), 0QWF47Z (autologous tissue substitute) and 0QWF4JZ (synthetic 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.
