About 03WY33Z

03WY33Z is the ICD-10-PCS code for a revision procedure on the upper artery using a percutaneous approach with infusion 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 incision of vessel, upper limb vessels, the ICD-9-CM procedure title it maps to (38.03).

The same procedure with a different approach is coded 03WY03Z (open), 03WY43Z (percutaneous endoscopic) and 03WYX3Z (external).

With a different device, use 03WY30Z (drainage device), 03WY32Z (monitoring device), 03WY37Z (autologous tissue substitute), 03WY3CZ (extraluminal device), 03WY3DZ (intraluminal device), 03WY3JZ (synthetic substitute) and 3 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.
