NOTES: Bars labeled 0 months represent the average annual out-of-pocket drug spending among beneficiaries who did not spend $2,250 or more in 2006 ($2,250 is the level of spending at which the so-called doughnut hole is reached). The bars labeled 1 month display the average out-of-pocket drug spending among those whose total drug spending reached $2,250 in December 2006; the bars labeled 2 months, among those whose spending reached $2,250 in November 2006; and so on.
