About 02WA3QZ

02WA3QZ is the ICD-10-PCS code for a revision procedure on the heart using a percutaneous approach with implantable heart assist system. 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 repair of heart assist system, the ICD-9-CM procedure title it maps to (37.63).

The same procedure with a different approach is coded 02WA0QZ (open), 02WA4QZ (percutaneous endoscopic) and 02WAXQZ (external).

With a different device, use 02WA32Z (monitoring device), 02WA33Z (infusion device), 02WA37Z (autologous tissue substitute), 02WA38Z (zooplastic tissue), 02WA3CZ (extraluminal device), 02WA3DZ (intraluminal device) and 6 more.

It is an operating-room procedure in the MS-DRG logic for DRG 215 (Other Heart Assist System Implant), DRG 001 (Heart Transplant or Implant of Heart Assist System with MCC) and DRG 002 (Heart Transplant or Implant of Heart Assist System without MCC), under the surgical categories “Other Heart Assist System Implant” and “Heart Transplant or Implant of Heart Assist System”.
