About 03WYXMZ

03WYXMZ is the ICD-10-PCS code for a revision procedure on the upper artery using an external approach with stimulator lead. 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 miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).

The same procedure with a different approach is coded 03WY0MZ (open), 03WY3MZ (percutaneous) and 03WY4MZ (percutaneous endoscopic).

With a different device, use 03WYX0Z (drainage device), 03WYX2Z (monitoring device), 03WYX3Z (infusion device), 03WYX7Z (autologous tissue substitute), 03WYXCZ (extraluminal device), 03WYXDZ (intraluminal device) and 2 more.

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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