About 02543ZZ

02543ZZ is the ICD-10-PCS code for a destruction procedure on the coronary vein using a percutaneous approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.

In plain terms, this corresponds to other operations on vessels of heart, the ICD-9-CM procedure title it maps to (36.99).

For a different body part, codes include 02553ZZ (atrial septum), 02563ZZ (right atrium), 02573ZZ (left atrium), 02583ZZ (conduction mechanism), 02593ZZ (chordae tendineae), 025D3ZZ (papillary muscle) and 16 more.

The same procedure with a different approach is coded 02540ZZ (open) and 02544ZZ (percutaneous endoscopic).

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) and DRG 317 (Concomitant Left Atrial Appendage Closure and Cardiac Ablation), under the surgical categories “Other Cardiothoracic Procedures” and “Concomitant Left Atrial Appendage Closure and Cardiac Ablation”.

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