About 02B80ZZ

02B80ZZ is the ICD-10-PCS code for a excision procedure on the conduction mechanism using an open 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, open approach, the ICD-9-CM procedure title it maps to (37.33).

For a different body part, codes include 02B40ZZ (coronary vein), 02B50ZZ (atrial septum), 02B60ZZ (right atrium), 02B70ZZ (left atrium), 02B90ZZ (chordae tendineae), 02BD0ZZ (papillary muscle) and 16 more.

The same procedure with a different approach is coded 02B83ZZ (percutaneous) and 02B84ZZ (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.
