About 0QWC04Z

0QWC04Z is the ICD-10-PCS code for a revision procedure on the left lower femur using an open approach with internal 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, femur, the ICD-9-CM procedure title it maps to (77.15).

For a different body part, codes include 0QW004Z (lumbar vertebra), 0QW104Z (sacrum), 0QW204Z (right pelvic bone), 0QW304Z (left pelvic bone), 0QW404Z (right acetabulum), 0QW504Z (left acetabulum) and 18 more.

The same procedure with a different approach is coded 0QWC34Z (percutaneous), 0QWC44Z (percutaneous endoscopic) and 0QWCX4Z (external).

With a different device, use 0QWC05Z (external fixation device), 0QWC07Z (autologous tissue substitute), 0QWC0JZ (synthetic substitute) and 0QWC0KZ (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 498 (Local Excision and Removal of Internal Fixation Devices of Hip and Femur with CC/MCC) and DRG 499 (Local Excision and Removal of Internal Fixation Devices of Hip and Femur without CC/MCC), under the surgical category “Local Excision and Removal of Internal Fixation Devices of Hip and Femur”.

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