Medicare Supplement coverage chart in Colorado

Medigap plans have the same coverage no matter what state you live in. Wisconsin, Minnesota, and Massachusetts exceptions don’t follow federal guidelines, meaning their Medigap plans differ from the standardized model!

Colorado’s Medicare Supplement Plans F, G, and N are the most popular. Plan C and Plan F are only available for Medicare beneficiaries who were eligible for Medicare before January 1, 2020.

We also expect enrollments to continue to increase for Plan G and Plan N over the next few years because new beneficiaries can no longer enroll in Plans F or C.

What Colorado Medicare Supplement plan is best for me?

With everyone’s needs being different, figuring out the correct Medicare Supplement for you can be challenging.

All Medigap plans have the same coverage, but that doesn’t mean that all companies are equal. Some Medigap providers excel in other areas, such as customer service claims payment. We pride ourselves in assisting you in finding a carrier that fits your individual needs.

Since our health may be good now, sometimes we consider a less comprehensive plan to save some money. Unfortunately, we don’t know what the future holds.

It’s wise to factor in your current and future health needs. Considering family history will help in trying to plan for what may come.

Price is important because you don’t want to overpay for the same coverage, but it’s wise to consider well-known and financially stable companies. Doing this will help ensure you have the intangibles, such as excellent customer service.
