Insurers cut 2015 Medicare drug plans

The average monthly premium for all plans will fall 2 percent, to $38.95, and the average for the top 10 plans will fall 6 percent, to $36.39.

Meanwhile, as the premiums fall, out-of-pocket costs are rising. The share of Part D plans with no deductible will fall to 42 percent, from 47 percent.

The Avalere analysts also took another look at the Medicare Advantage plan data, on a county-by-county basis. They found that the average number of plans is falling in some Mid-Atlantic counties and parts of New England but increasing in most of the rest of New England, and in many counties in California, Idaho, Illinois, Kentucky, Louisiana, Michigan, Montana, Oklahoma, Tennessee and Wisconsin.
