About 0QWY3MZ

0QWY3MZ is the ICD-10-PCS code for a revision procedure on the lower bone using a percutaneous approach with bone growth stimulator. 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).

The same procedure with a different approach is coded 0QWY0MZ (open), 0QWY4MZ (percutaneous endoscopic) and 0QWYXMZ (external).

With a different device, use 0QWY30Z (drainage device).

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.
