About 02WA4YZ
02WA4YZ is the ICD-10-PCS code for a revision procedure on the heart 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 Cardiotomy, the ICD-9-CM procedure title it maps to (37.11).
For a different body part, codes include 02WY4YZ (great vessel).
The same procedure with a different approach is coded 02WA0YZ (open) and 02WA3YZ (percutaneous).
With a different device, use 02WA42Z (monitoring device), 02WA43Z (infusion device), 02WA47Z (autologous tissue substitute), 02WA48Z (zooplastic tissue), 02WA4CZ (extraluminal device), 02WA4DZ (intraluminal device) and 6 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.
