More older Americans about are thinking about changing their Medicare plans, but the actual percentage of Medicare beneficiaries who want to switch is still low.

Allsup Inc., Belleville, Ill., has published figures supporting those conclusions in a summary of results from a recent telephone survey of 200 individuals ages 65 and older who have Medicare.

Only 5% of the survey participants said they had changed Medicare plans since they become eligible for Medicare. About 16% of the survey participants are thinking about changing Medicare plans in 2010, according to Allsup, a firm that offers Medicare advice services to Medicare beneficiaries.

Medicare-eligible individuals can switch plans from Nov. 15 to Dec. 31.

About 80% of the survey participants said they have stayed with their plans because they have been satisfied with their coverage.

For participants who have stayed with plans they dislike, the difficulty of understanding Medicare options and comparing plans has been a significant problem: about 60% of those survey participants said that changing plans is too confusing, or that comparing plans is too difficult.
