Medicare guide
What a Medicare Supplement plan covers, how plan letters work, and why timing matters. Free, no-pressure help from a local agent.
A Medicare Supplement plan, also called Medigap, is a policy sold by private insurance companies that works alongside Original Medicare (Part A and Part B). Original Medicare pays a large share of your medical costs, but you are still responsible for deductibles, copays, and coinsurance. A Medigap plan is designed to help pay some or all of those costs.
To buy one, you must be enrolled in both Part A and Part B. A Medigap policy covers one person, so spouses each need their own.
In most states, including Utah, Medigap plans are identified by letters, such as Plan G or Plan N. The benefits of each lettered plan are standardized, which means a given plan offers the same basic benefits no matter which company sells it. What differs between companies is the premium, and sometimes how the premium is set and how it may change over time.
Not every lettered plan is available to everyone. For example, plans C and F are not available to people who first became eligible for Medicare on or after January 1, 2020. We confirm which plans you can buy when we review your options.
When you are 65 or older and enrolled in Part B, you get a one-time 6-month Medigap Open Enrollment Period. During those six months, insurers generally cannot deny you a Medigap policy or charge you more because of your health. Outside that window, many insurers can ask health questions and may decline an application or charge more, unless you have a guaranteed issue right (for example, in certain situations when you lose other coverage).
That is why we recommend looking at Medigap early, before you need it. Annual Enrollment (October 15 to December 7) does not give Medigap shoppers the same protections. Switching Medigap plans later may involve health underwriting.
Companies price Medigap in different ways. Some base the premium on your age when you first buy the plan, while others base it on your current age, so the premium may rise as you get older. Premiums can also increase over time because of inflation and claims costs. When we quote plans, we explain how each company prices its policy, not only what it costs today.
Our Medicare Advantage guide covers the other side. We are happy to walk through both with you.
We compare Medicare Supplement plans from the carriers we represent, explain how each prices its policy, and check which plans you are eligible for. Our help is free to you, since carriers pay our commission, and the price of a plan is the same whether you buy through us or directly. You decide, with no pressure.
No. Medigap does not include drug coverage. If you choose Original Medicare with a Medicare Supplement plan, you would add a separate Part D prescription drug plan.
You can see any doctor or hospital in the United States that accepts Medicare. You do not need a network or referrals for Medicare-covered care, though each provider decides whether to accept new Medicare patients.
It can. Companies set premiums differently, and premiums may increase as you age or over time because of rising costs. We explain how each quoted plan prices its policy before you decide.
Often yes, but switching may involve health questions, and a company may decline an application or charge more. You are only guaranteed the right to buy a Medigap policy without health questions during your Medigap Open Enrollment Period or in certain special situations.
No. Our consultations are free, and carriers pay our commission. Your premium is the same whether you buy through us or directly from a company.
