To some degree, that is already done with Medicare Plan D for medications. For the first time, I had to participate in this to get help on an expensive medication, and found out that the participant can select the insurance provider, as well as the pharmacy, local or mail-in. This has put pharmaceuticals and insurances on a competitive basis for the Plan D portion. The insurance cost is dependent on the particular medication costs, and can be taken out of the Social Security check.
And medication is the first line of defense in preventative medicine. Always thought George Jr. Was a genius for cutting medicare costs with an affordable drug program of choice.
