Wiki Repair of left ventricular aneurysm

[R1CPC]

Hi there, pt is under going a CABG surgery and during the surgery the physician discovers a ventricle aneurysm so he decides to repair it by entering the left ventricle and suturing a pericardial patch to the inner part and healthier part of the left ventricle. How would we code this? I was thinking 33542 however it does not say he excised the aneurysm. Please help

insertion of a patch is 33548

I thought 33548 is only used if the heart is restored to it's normal shape? The note doesn't talk about reshaping the left ventricle only suturing a patch. My concern is that I'm going to over code this service.
