About 02B43ZZ

02B43ZZ is the ICD-10-PCS code for a excision procedure on the coronary vein using a percutaneous 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 other operations on vessels of heart, the ICD-9-CM procedure title it maps to (36.99).

For a different body part, codes include 02B53ZZ (atrial septum), 02B63ZZ (right atrium), 02B73ZZ (left atrium), 02B83ZZ (conduction mechanism), 02B93ZZ (chordae tendineae), 02BD3ZZ (papillary muscle) and 16 more.

The same procedure with a different approach is coded 02B40ZZ (open) and 02B44ZZ (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.
