Shop around to compare plans or consider switching to a Medicare Advantage plan to lower your costs. By Kimberly Lankford, Contributing Editor September 27, 2012 Premiums for my medigap policy have been increasing over the past few years. What can I do to lower the cost? If you like the coverage offered by your current policy, see if other companies are offering a better deal for the same-letter plan. Under federal law, insurers who provide medigap coverage -- which helps pay out-of-pocket costs for Medicare services, including Part A and Part B -- may sell only standardized policies identified by letters A through N in most states. Each policy identified by the same letter must offer the same benefits. Usually, the only difference between same-letter policies is cost -- and the price range can be surprisingly large. A man who recently enrolled in Medicare may be charged $934 to $5,590 annually for the most popular, Plan F policy, according to PlanPrescriber.com, a plan-comparison tool. Sponsored Content Some insurers also offer high-deductible Plan F policies, which require you to pay $2,070 before coverage kicks in. Premiums for these policies range from about $600 to $960 per year. Also look at Plan N, a newer plan that includes some cost-sharing. Plan N covers many of the same expenses as Plan F, including the full $1,156 Part A deductible for inpatient hospital services. But it doesn’t cover the $140 Part B deductible, and there is also a $20 co-payment for doctors’ office visits and a $50 co-payment for emergency-room visits. The average Plan N policy in PlanPrescriber’s database costs a man $1,470 a year, compared with $2,107 a year for Plan F.

These all-in-one plans provide medical and prescription-drug coverage through private insurers, and you cannot be rejected or charged more because of your health. The premiums for Medicare Advantage plans are generally lower than if you buy medigap coverage plus a Medicare Part D prescription-drug plan, but you are usually limited to a network of doctors and hospitals. Open enrollment for Medicare Advantage plans runs from October 15 to December 7 for plans that take effect on January 1, 2013. If you go with a medigap policy, pay attention to the pricing system. Some plans base their pricing on “issue age,” which means that their rates rise with medical inflation. Some are “attained age” policies, whose prices increase every year with the policyholder’s age and also track medical inflation. And some are “community rated” policies, which charge everyone in the community the same price regardless of age. The lowest-cost issue-age or community-rated policy is usually cheaper than an attained-age policy over time. Unlike Part D prescription-drug and Medicare Advantage plans, there is no open-enrollment season for medigap policies. Insurers can’t reject you or charge more based on your health if you get a medigap plan within six months of signing up for Medicare Part B. After that, you may switch medigap policies at any time, but you could be rejected or charged more because of your health. Because some medigap policies cost much more than others, you could still save money on a new policy even if you have moderate health issues. Also, a few companies do offer policies without medical underwriting in some states, and some insurers let you switch into Plan N regardless of your health as long as your old plan was with the same company.
