I understand that, but IF that's what they can do, their profits would be far larger.No, because they still spent the $800k on care. The rebates are a separate stream of revenue, not subject to 80/20. Like how if the same umbrella owns the insurer and PBM there's an incentive for the insurer to use that PBM and for the PBM to overcharge the insurer because the PBM isn't subject to 80/20.
The whole point in both cases is to have money that's actually profit but isn't on the 20 side of the 80/20 rule.
