I want to know the average, or typical percent of subsidization
medicare pays on the Part D drug coverage plan.  I realize it's
different on each drug, but I am looking for an approximate average. 
In other words, Is the plan D drug coverage subsidizing insurance
companies in the 10 to 20% range, or is it higher. I just need an
approximate or average percent of the drug costs that medicare
reimburses to the insurance companies.  I'm having a difficult time
verbalizing this question.  Try to be patient :)
