About 025D0ZZ

025D0ZZ is the ICD-10-PCS code for a destruction procedure on the papillary muscle using an open 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 operations on papillary muscle, the ICD-9-CM procedure title it maps to (35.31).

For a different body part, codes include 02540ZZ (coronary vein), 02550ZZ (atrial septum), 02560ZZ (right atrium), 02570ZZ (left atrium), 02580ZZ (conduction mechanism), 02590ZZ (chordae tendineae) and 16 more.

The same procedure with a different approach is coded 025D3ZZ (percutaneous) and 025D4ZZ (percutaneous endoscopic).

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.
