Medicare Prescription drug plans jump 8%

Popular Medicare drug plans are in for an increase in premiums of nearly 10 percent next year, according to a new study.

An analysis from the healthcare research firm Avalere Health found that the 10 most popular Medicare Part D prescription plans would have an average increase of 8 percent next year. But on the flip side, a higher percentage of Medicare Advantage beneficiaries will have no premium in 2016.

A Medicare beneficiary receives prescription drug coverage from Part D or Medicare Advantage, which is a program that allows beneficiaries to buy a private plan.
