How do these numbers add up to savings?

I recently came across this story that says that hospitals have agreed to give up $155 billion in future Medicare and Medicaid payments to help defray the costs of President Obamas healthcare plan. This piece of news was seen as the bright spot in the White House effort to reform healthcare. Digging deeper into the story I’m amazed how this can be seen as positive news for people interested in reducing healthcare costs.

About $50 billion of this projected $155 billion “savings” is expected to come from a reduction in payments made to hospitals that provide care to uninsured and low income patients. The effected hospitals say this will put a strain on these local communities. These reductions come from payments currently made by Medicare and Medicaid (Government).

The story goes on to detail that in exchange for giving up $155 billion in future payments, the hospitals have negotiated a deal should the Finance Committees’ (Government) legislation include a public health insurance plan. Under this agreement, the hospitals would receive reimbursement amounts in excess of what Medicare and Medicaid currently pay.

So hospitals have agreed  give up a lesser amount from Medicare and Medicaid (Government) in exchange for higher reimbursements under potential Finance Committee’s legislation(Government). How does this end up saving any money on healthcare expenses. Where does the average citizen realize any savings in this plan?
