Reasons for Medigap plan popularity
There are several reasons why consumers choose certain Medigap plan options over others.
The most popular Medigap plans — Plan C and Plan F — are the most benefits-rich plans in the Medicare Supplement insurance market. Plans F and C are often called “first-dollar coverage” Medigap plans because each covers all of the Medicare deductibles and co-insurance.
Although first-dollar coverage Medigap plans are the most popular, some beneficiaries choose other plan options with fewer benefits, likely because these plans tend to be cheaper. Plans with limited benefits, such as Plan A and Plan B, can offer lower premium costs than other plans.
Some beneficiaries choose a Medigap plan based on benefits or price, but other times it is a combination of these and other factors. In a 2013 report, the Kaiser Family Foundation (KFF) said that it is “not entirely clear how beneficiaries choose among Medigap plans, whether they are motivated mainly by low premiums, a comfort level with a brand, or some combination of factors.”
KFF did elaborate that the standardization of benefits helps beneficiaries compare and contrast various Medigap benefits and premiums between different plans.
Another reason why certain plans are more popular than others is due to plan availability. In most states, insurance companies can offer a range of the 10 available Medigap plans. Some insurers offer the bare minimum Plan A, while others offer nearly all Medigap plans. For example, the KFF report found that Plan A was offered by 86% of insurance companies while only 9% offered Plan M.
