Medicare Supplement Plans (Medigap) in Colorado

Last Updated on

Medicare Supplement (or Medigap) plans in Colorado are available through private insurance companies, as they are in other states. They’re designed to help pay for costs that you incur under Original Medicare, like copayments, coinsurance, and deductibles. As a Medicare beneficiary in Colorado, you may have several Medigap plan options, depending on the part of Colorado you live in. Understand what each Medigap plan covers, and get help selecting the one that may work for your health and budget needs.

How Medigap plans work in Colorado

Medigap plans in Colorado (and the rest of the United States) help cover health-care costs associated with Original Medicare, Part A and Part B, such as copayments, coinsurance, plan deductibles, and other out-pocket expenses. There are 10 standardized plans labeled by one of 10 letters (A, B, C, D, F, G, K, L, M, and N), and all plans of the same letter offer the same benefits. The same 10 plans are available in 47 states, including Colorado. Three states – Massachusetts, Minnesota, and Wisconsin – offer different Medigap plans.

You must already be enrolled in Original Medicare, Part A and Part B, to sign up for a Medicare Supplement plan in Colorado, as in other states. Your Medigap Open Enrollment Period may be the best time to join a Medigap plan.  This period starts the first day you are age 65 or older and also enrolled in Medicare Part B, and it lasts for six months. During this time, you can sign up for any Medicare Supplement plan available in your area, with the insurance company of your choosing, and not be subject to medical underwriting or any restrictions for pre-existing conditions. This means that an insurance company can neither deny you enrollment in, nor charge you more for, a Medicare Supplement plan. You can apply for a Medigap plan after the Medigap Open Enrollment Period is over, but you may be denied coverage or charged more for the insurance policy.

Medigap plans sold today do not offer prescription drug coverage, so you may want to enroll in a stand-alone Medicare Part D Prescription Drug Plan to receive coverage for drug expenses. Medicare Part D Prescription Drug Plans in Colorado are available through private insurance companies, as they are in other states.

If you sign up for a Medigap plan, you must remain enrolled in Original Medicare, Part A and Part B, and continue paying your Medicare Part B premium. Medigap plans are meant to work alongside Original Medicare; failure to pay your Medicare Part B premium may result in your being disenrolled from Medicare and losing your health coverage.

**Once you reach the out-of-pocket limits (including the Part B deductible), both Medicare Supplement Plans K and L pay 100% of covered services in the above chart for the remainder of the calendar year.

Choosing a Medigap plan in Colorado

As stated earlier, Medicare Supplement plans in Colorado with the same letter designation don’t vary in coverage or benefits. However, each independent insurance company offering Medicare Supplement plans can determine its own monthly premium structure. This means that a resident of Boulder in Boulder County may pay more or less than a resident of Fort Collins in Larimer County for an identical Medicare Supplement plan. It may be a good idea for you to compare all Medicare Supplement plans in Colorado that are available to you, and then make a selection based on your individual budget and health needs.
