Cabg blunder

Hello family, I need your help and please advise me if I am wrong.

Can you bill 33511 and 33533 together?

If you can, please provider example or reference where I can have for notes.

If no, I didn't think we could code a CABG like this. If we could code this way, what would be the purpose of the 33517-33523 add-on codes?

I am auditing myself and this question came up.

Thanks Family,
