Medicare plays a key role in providing health and financial security to beneficiaries residing in Montana. With more than 234,800 Montana beneficiaries enrolled in Medicare, we’ll cover some very important information below about Medicare in Montana. We want to help you better understand your options and make the decision-process as seamless as possible once you’re ready to enroll in Medicare or discover different coverage options.

Who Qualifies for Medicare in Montana?

Medicare covers most Montana residents who are 65 or older, and it also covers disabled Montana residents. In general, Medicare enrollment in Montana works the same way as it does in the rest of the country. If you qualify for Original Medicare, also known as Part A and Part B, it will help cover 80% of your health care costs.

When you’re first eligible for Medicare, you have a 7-month Initial Enrollment Period to sign up for Part A and/or Part B. If you’re eligible for Medicare when you turn 65, you can sign up during the 7-month period that:

  • Begins 3 months before the month you turn 65
  • Includes the month you turn 65
  • Ends 3 months after the month you turn 65

In most cases, if you don’t sign up for Part B when you’re first eligible, you’ll have to pay a late enrollment penalty. You’ll be responsible for paying this penalty for as long as you have Part B, and you could have a gap in your health coverage.

Once you reach Medicare eligibility, you can begin choosing additional coverage options to help pay for the remaining 20% of your medical expenses through Medicare Advantage (Part C), Medigap, and/or a Medicare Prescription Drug (Part D) plan.

Montana Medicare Advantage Plans (Part C)

Only 19% of Montana Medicare beneficiaries select Medicare Advantage plans.

Medicare Advantage plans are private, Medicare-approved insurance companies. They provide all of your Original Medicare benefits and often include extra benefits such as drug, dental, and vision coverage.

The Medicare Advantage Open Enrollment Period runs from January 1 to March 31. During this period, Medicare beneficiaries in Montana who already enrolled in a Medicare Advantage plan can switch to a different Medicare Advantage plan or drop their Medicare Advantage plan and enroll in Original Medicare.

As of 2020, 15 Medicare Advantage plans are available in Montana. The average monthly Medicare Advantage premium changed from $53.13 in 2019 to $51.84 in 2020. $0 is the lowest monthly premium for a Medicare Advantage plan in Montana. All 56 of Montana’s counties have Medicare Advantage plans available. The availability of Medicare Advantage plans can range from one to nine, depending on the county.

According to the Centers for Medicare and Medicaid Services (CMS), as of May 2020, there are 48,020 beneficiaries enrolled in Medicare Advantage and other plans in Montana. Only 19% of Montana Medicare beneficiaries were enrolled in a private Medicare Advantage plan in 2019. 100% of people with Medicare have access to a Medicare Advantage plan.

Montana Medicare Supplement (Medigap) Insurance Plans

Montana requires Medigap insurers to offer plans to disabled Medicare beneficiaries under the age of 65.

Medigap plans are used to supplement Original Medicare, covering some or all of the out-of-pocket costs (for coinsurance and deductibles) that beneficiaries would otherwise incur if they only had Original Medicare on its own. Typically, Medigap plans are popular for those who want little to no copay when they access healthcare services.

There are two initial times to enroll in a Medigap plan before and after you turn 65:

  • 6 months prior to turning 65
  • Once you turn 65, your 6 month period begins the month you enroll in Part B

During this period, an insurance company can’t use medical underwriting. 

Medigap insurers in Montana can choose to use attained-age rating, issue-age rating, or community rating. Although federal rules don’t require Medigap insurers to offer plans to Medicare beneficiaries under age 65 who are eligible for Medicare due to a disability, Montana does require Medigap insurers to offer coverage to disabled Medicare beneficiaries.

Montana Medicare Prescription Drug Coverage (Part D)

Original Medicare doesn’t cover outpatient prescription drugs. However, Medicare beneficiaries can get prescription coverage via a Medicare Advantage plan, an employer-sponsored plan (offered by a current or former employer), or a stand-alone Part D plan. Medigap plans don’t cover prescription drugs unless they’re covered under Part B.

As of 2020, There are 119,388 Medicare beneficiaries in Montana enrolled in stand-alone Part D prescription drug plans and 43,844 enrolled in Medicare Advantage Prescription Drug plans. For 2020 coverage, there are 29 stand-alone Part D plans available in Montana, with premiums ranging from about $15 to $94 per month. About 23% of people with a stand-alone Medicare prescription drug plan get Extra Help (also called the low-income subsidy, or LIS).

When deciding on a Part D plan, it’s important to evaluate several factors such as each plan’s premium, formulary, and copays since every plan is different.
