About 02594ZZ

02594ZZ is the ICD-10-PCS code for a destruction procedure on the chordae tendineae using a percutaneous endoscopic 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 excision or destruction of other lesion or tissue of heart, thoracoscopic approach, the ICD-9-CM procedure title it maps to (37.37).

For a different body part, codes include 02544ZZ (coronary vein), 02554ZZ (atrial septum), 02564ZZ (right atrium), 02574ZZ (left atrium), 02584ZZ (conduction mechanism), 025D4ZZ (papillary muscle) and 16 more.

The same procedure with a different approach is coded 02590ZZ (open) and 02593ZZ (percutaneous).

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.
