Wiki CABG question

[Chelsea1]

On one report I have:

Saphenous vein to the RCA, Circumflex, diagonal LAD
Left IMA to the mid distal LAD


The second report I have:

Saphenous vein to the circumflex X 2 and also to the RC, LAD
Mammory artery to the LAD

My question is how would I count these in regards to sequential grafts?

For the first report you would code 33533, 33519 and if the Saphenous vein is harvested endoscopic then 33508 would be appropriate.
For the second report 33533, 33521
