About 04WY3YZ
04WY3YZ is the ICD-10-PCS code for a revision procedure on the lower artery using a percutaneous approach with other 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, lower limb arteries, the ICD-9-CM procedure title it maps to (38.08).
The same procedure with a different approach is coded 04WY0YZ (open) and 04WY4YZ (percutaneous endoscopic).
With a different device, use 04WY30Z (drainage device), 04WY32Z (monitoring device), 04WY33Z (infusion device), 04WY37Z (autologous tissue substitute), 04WY3CZ (extraluminal device), 04WY3DZ (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 was added in FY2018, effective October 1, 2017.
