About 025M3ZZ

025M3ZZ is the ICD-10-PCS code for a destruction procedure on the ventricular septum 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 excision or destruction of other lesion or tissue of heart, endovascular approach, the ICD-9-CM procedure title it maps to (37.34).

For a different body part, codes include 02543ZZ (coronary vein), 02553ZZ (atrial septum), 02563ZZ (right atrium), 02573ZZ (left atrium), 02583ZZ (conduction mechanism), 02593ZZ (chordae tendineae) and 16 more.

The same procedure with a different approach is coded 025M0ZZ (open) and 025M4ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 273 (Percutaneous and Other Intracardiac Procedures with MCC) and DRG 274 (Percutaneous and Other Intracardiac Procedures without MCC), under the surgical category “Percutaneous and Other Intracardiac Procedures”.

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