About 02WA43Z

02WA43Z is the ICD-10-PCS code for a revision procedure on the heart using a percutaneous endoscopic 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 Cardiotomy, the ICD-9-CM procedure title it maps to (37.11).

For a different body part, codes include 02WY43Z (great vessel).

The same procedure with a different approach is coded 02WA03Z (open), 02WA33Z (percutaneous) and 02WAX3Z (external).

With a different device, use 02WA42Z (monitoring device), 02WA47Z (autologous tissue substitute), 02WA48Z (zooplastic tissue), 02WA4CZ (extraluminal device), 02WA4DZ (intraluminal device), 02WA4JZ (synthetic substitute) and 6 more.

It is an operating-room procedure in the MS-DRG logic for DRG 228 (Other Cardiothoracic Procedures with MCC) and DRG 229 (Other Cardiothoracic Procedures without MCC), under the surgical category “Other Cardiothoracic Procedures”.

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