WSJ: ACA to eat up Medicare Part D's doughnut hole by 2020

NEW YORK — Next year, the share of brand-name drugs paid by Medicare Part D beneficiaries will drop to 47.5%. The share of generics will drop to 72%, according to a report published Monday in The Wall Street Journal.

And by 2020, the Patient Protection and Affordable Care Act will have bridged the gap between what has commonly been referred to as the doughnut hole altogether — seniors will continue to cover only 25% of the cost of either brand-name medicines or generic medicines. 

"Thanks to the Affordable Care Act, which had a rocky launch last week, Medicare beneficiaries will see that gap shrink again in 2014 and in each year until 2020, according to Medicare.gov," The Wall Street Journal reported.
