About 02BG4ZZ

02BG4ZZ is the ICD-10-PCS code for a excision procedure on the mitral valve using a percutaneous endoscopic approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

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 02B44ZZ (coronary vein), 02B54ZZ (atrial septum), 02B64ZZ (right atrium), 02B74ZZ (left atrium), 02B84ZZ (conduction mechanism), 02B94ZZ (chordae tendineae) and 16 more.

The same procedure with a different approach is coded 02BG0ZZ (open) and 02BG3ZZ (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.
