About 02WA0RS

02WA0RS is the ICD-10-PCS code for a revision procedure on the heart using an open approach with short-term external heart assist system (qualifier: biventricular). 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 02WA3RS (percutaneous), 02WA4RS (percutaneous endoscopic) and 02WAXRS (external).

It is an operating-room procedure in the MS-DRG logic for DRG 215 (Other Heart Assist System Implant), under the surgical category “Other Heart Assist System Implant”.

It was added in FY2018, effective October 1, 2017.
