Medicare is a lifesaver for folks who qualify for it. But like most insurance policies, Medicare doesn’t cover 100 percent of your medical expenses. Original Medicare (Parts A and B) doesn’t cover prescription drugs, and can leave you owing money to health care providers for annual deductibles, office visit copays and other charges.

One way to cover those extra health expenses is with a “Medigap” policy—a supplemental health insurance policy intended to cover the cost “gaps” left by Medicare. “If you can afford a Medigap plan—with premiums ranging from about $40 to $140 a month depending on benefits—it’s a great way to eliminate significant out-of-pocket medical costs,” says Cindy Holtzman, a licensed health insurance agent based in Marietta, Ga. “Better yet, you don’t have to worry about whether your doctor is ‘on your plan.’ Any professional who takes Medicare will also be covered by your Medigap plan.”

You should buy a Medigap policy is when your Medicare eligibility kicks in, a six-month period beginning the first day of the month during which you turn 65 and have enrolled in Medicare Part B. During this initial enrollment period, you’re automatically approved for a policy without medical underwriting. Insurance companies can’t deny you coverage or charge more for your policy due to a pre-existing health condition.

There are many different “flavors” of Medigap plans, distinguished from each other by an alphabet soup of letters: Parts F, G, K, L, M and N. Each “letter plan” pays differently: Some cover your deductibles, others don’t. Some plans cover 100 percent of your office visit copays, others pay a percentage. Some states allow residents to choose from the entire range of plans, while other states only allow a handful of options. (Find out what plans your state approves at

Once you know your plan options, do a cost comparison. List your guesstimated medical expenses for the upcoming year. How many doctor’s office visits and lab tests do you usually need? (Check last year’s insurance files if you’re not sure.) Do you go in for regular dialysis treatments? Is an emergency room visit a possibility? Note the price for these services (available in the plan’s outline of benefits) for each Medigap plan you’re considering and total them up. Add in each plan’s annual premium and any deductibles, then compare overall costs to see which plan makes the best financial sense for you.

2. How much can you afford to pay in premiums per month?

4.How financially stable is the insurer?
Check the insurer’s financial stability through rating agencies like or Ask friends and relatives who have a Medigap policy how they like their company. Your state’s insurance department should also have records of complaints that have been made against each insurance company.
