CHICAGO, Feb 22: There will be good and bad news next year for seniors using Medicare’s prescription drug program. Overall, enrollees can expect a year of flat or decreasing Medicare prescription drug costs, according to data released last week by the federal government. The government said Medicare’s per-beneficiary drug costs fell 4 percent last year. As a result, some of the most important numbers in the program’s 2014 Part D will drop by roughly the same amounts.
