About 02WAXRZ

02WAXRZ is the ICD-10-PCS code for a revision procedure on the heart using an external approach with short-term external 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 other miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).

The same procedure with a different approach is coded 02WA0RZ (open), 02WA3RZ (percutaneous) and 02WA4RZ (percutaneous endoscopic).

With a different device, use 02WAX2Z (monitoring device), 02WAX3Z (infusion device), 02WAX7Z (autologous tissue substitute), 02WAX8Z (zooplastic tissue), 02WAXCZ (extraluminal device), 02WAXDZ (intraluminal device) and 5 more.

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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