What do you have against building upon existing ideas? It is no surprise that large health organizations would offer discounts to large groups. Some doctors are now offering similar discounts to individuals. For example, I got tired of paying high premiums for dental insurance, feeling that I wasn't getting much at all for my expenses other than the negotiated discount. I told my dentist how I felt. He made the offer to extend those same discounts to me (and sometimes even better pricing) so I now purchase my services directly from him with no insurance company involvement.
