About 0QW447Z

0QW447Z is the ICD-10-PCS code for a revision procedure on the right acetabulum using a percutaneous endoscopic approach with autologous 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, other bones, the ICD-9-CM procedure title it maps to (77.19).

For a different body part, codes include 0QW047Z (lumbar vertebra), 0QW147Z (sacrum), 0QW247Z (right pelvic bone), 0QW347Z (left pelvic bone), 0QW547Z (left acetabulum), 0QW647Z (right upper femur) and 18 more.

The same procedure with a different approach is coded 0QW407Z (open), 0QW437Z (percutaneous) and 0QW4X7Z (external).

With a different device, use 0QW444Z (internal fixation device), 0QW44JZ (synthetic substitute) and 0QW44KZ (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) and DRG 497 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur without CC/MCC), under the surgical category “Local Excision and Removal of Internal Fixation Devices Except Hip and Femur”.

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