definiton of artery vs branch

The CPT definition of 92920 is Angioplasty single major coronary artery or branch. And 92982 is the stent with angio artery or branch .

If the provider documents angioplasty on one (1) lesion in the Left Main and then places a stent another lesion in 1st Obtuse Marginal. Can 92920 and 92928. Be billed(this would be for a Medicare patient that bundles 92921 &92929.
This is to get clarification for an office that is interpreting the definitions differently.
Thanks for your help.
