About 03WY4YZ
03WY4YZ is the ICD-10-PCS code for a revision procedure on the upper artery using a percutaneous endoscopic 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, upper limb vessels, the ICD-9-CM procedure title it maps to (38.03).
The same procedure with a different approach is coded 03WY0YZ (open) and 03WY3YZ (percutaneous).
With a different device, use 03WY40Z (drainage device), 03WY42Z (monitoring device), 03WY43Z (infusion device), 03WY47Z (autologous tissue substitute), 03WY4CZ (extraluminal device), 03WY4DZ (intraluminal device) 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 was added in FY2018, effective October 1, 2017.
