About 02WA0CZ
02WA0CZ is the ICD-10-PCS code for a revision procedure on the heart using an open approach with extraluminal 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 02WY0CZ (great vessel).
The same procedure with a different approach is coded 02WA3CZ (percutaneous), 02WA4CZ (percutaneous endoscopic) and 02WAXCZ (external).
With a different device, use 02WA02Z (monitoring device), 02WA03Z (infusion device), 02WA07Z (autologous tissue substitute), 02WA08Z (zooplastic tissue), 02WA0DZ (intraluminal device), 02WA0JZ (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.
