About 02WA4KZ
02WA4KZ is the ICD-10-PCS code for a revision procedure on the heart using a percutaneous endoscopic approach with nonautologous tissue substitute. 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 02WF4KZ (aortic valve), 02WG4KZ (mitral valve), 02WH4KZ (pulmonary valve), 02WJ4KZ (tricuspid valve) and 02WY4KZ (great vessel).
The same procedure with a different approach is coded 02WA0KZ (open), 02WA3KZ (percutaneous) and 02WAXKZ (external).
With a different device, use 02WA42Z (monitoring device), 02WA43Z (infusion device), 02WA47Z (autologous tissue substitute), 02WA48Z (zooplastic tissue), 02WA4CZ (extraluminal device), 02WA4DZ (intraluminal device) and 6 more.
It is an operating-room procedure in the MS-DRG logic for DRG 228 (Other Cardiothoracic Procedures with MCC), DRG 229 (Other Cardiothoracic Procedures without MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC), DRG 909 (Other O.R. Procedures for Injuries without CC/MCC) and DRG 957 (Other O.R. Procedures for Multiple Significant Trauma with MCC), under the surgical categories “Other Cardiothoracic Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
