  • Of the ten plans offered in 2023, we found Medicare Supplement Plan G is the best plan for the most comprehensive coverage. Cigna offers the cheapest Plan G rates, coming in at $105.56 per month.
  • Cigna also offers the highly valued Medicare Supplement Plan N at $72.24 monthly.
  • And for those wanting the lowest monthly rate, High Deductible Plan G from Mutual of Omaha offers the best rates at $47.96 per month. You must pay a $2,700 annual deductible before the plan starts covering costs.

Below are highlighted features and benefits of each plan.

Best Plan G:

    What's the Best Medicare Supplement Company in Colorado?

    Based on our review of several key factors, Cigna is the best Medicare Supplement company in Colorado.

    While Cigna Medigap plans tend to be more affordable in Colorado, it's not the only factor when selecting the best Medicare Supplement company.

    When Can I Apply For a Medicare Supplement Plan?

    Open Enrollment Period

    Your Open Enrollment Period is the best time to enroll in a Medicare Supplement Plan. This period is six months long and starts the first month that you have Medicare Part B coverage and are 65 or older.

    The 6-month enrollment period cannot be postponed or repeated. Medicare beneficiaries receive the best rates inside this six-month window and have guaranteed issue rights, which means the Medicare insurance company cannot deny coverage or increase prices, even if beneficiaries have pre-existing conditions.

    Outside the Medigap Open Enrollment Period

    Once your Medigap Open Enrollment Period ends, your application is reviewed by a medical underwriting team assigned to evaluate risk. Private insurance companies can approve policies at higher rates or deny coverage altogether.

    This is not applicable if you have guaranteed issue rights, which can be applied in situations such as a retiree losing coverage or having a plan that no more extends services in your area. These unique situations are called Special Enrollment Periods.

    In that case, the Medicare insurance company has to offer you the following:

    • At least one type of Medicare Supplement insurance plan in Colorado
    • Cover pre-existing conditions
    • Offer pricing irrespective of your health condition

    When Under 65

    Guaranteed issue rights apply to Colorado beneficiaries under 65 who have:

    • A qualifying disability
    • End-stage renal disease (ESRD)

    FAQ:

    When Can I Change Medigap Plans?

    Medicare Supplement plan members can switch Medigap policies at any time. However, insurance companies can ask health questions and require underwriting, which will raise your insurance prices.

    Eligibility for an exception may apply if you:

    • Have specific circumstances or guaranteed issue rights
    • Are within the six-month window of your Medigap Open Enrollment Period

    Once you switch, you have 30 days to decide to keep your new policy. This is called a Medigap Free Look Period.

    Can I De Denied Medigap Coverage?

    If you miss the Medigap Open Enrollment Period and do not qualify for guaranteed issue rights, an insurer may deny coverage under Medigap based on your health conditions.
