    Find Your Perfect Fit: How to Pick the Best Medicare Advantage Plan in Montana

    You may be looking at plans for several different reasons, including turning 65 or the Annual Enrollment Period. Or, perhaps you are navigating a special enrollment event, such as moving to a new area. In all of these cases, there are a few important details you need to consider.

    1. Evaluate How You Plan to Use Your Benefits

    Do you think you’ll take maximum advantage of your benefits (doctors, hospital inpatient care, tests, etc.)? If so, prioritize plans with lower out-of-pocket maximums and lower copayments, even if they have higher monthly premiums. Otherwise, look for plans with low monthly premiums. Just be aware that plans with low or no monthly premiums tend to have higher out-of-pocket maximums and/or higher deductibles.

    2. Examine Your Prescription Medication Expenses

    Prescription drugs are often the main reason that seniors pay more for healthcare. Because most Montana Medicare Advantage plans include Part D coverage for prescriptions, it is important to ensure you get the right plan that covers your drugs at a cost you can afford.

    3. Consider Your Needs for Additional Coverage

    Original Medicare doesn't cover all costs related to health care. It covers major medical expenses and preventative care services, however, it doesn't cover prescriptions, vision, hearing, or dental. Many of the essential services your Part A or Part B benefits don't cover are covered by Medicare Advantage plans.

    4. Think About Your Preferred Healthcare Providers

    Medicare Advantage plans have healthcare provider networks. Unfortunately, not all specialists and primary care doctors accept all plans. Many people on Medicare in Montana tell us it's difficult to find a plan their doctors take. We can help!

    Frequently Asked Questions

    Still have questions? These common questions and answers might help.

    What are the disadvantages of a Medicare Advantage plan?

    Medicare Advantage plans may have several disadvantages. Most plans require that their members use their network providers. It is also difficult to budget for healthcare costs as costs are largely determined by your use of healthcare services. Many plans require that members obtain referrals to a specialist before they are authorized to receive a service. Discover more disadvantages of Medicare Advantage plans.

    How much do Medicare Advantage plans cost in Montana?

    A Medicare Advantage plan in Montana costs an average of $nan. This is just the monthly premium. You should also consider the out-of-pocket expenses of a plan if you have any chronic conditions, which include a plan's copays and deductibles. Prescription drug benefits are also included in most Medicare Advantage plans, but they have their own out-of-pocket costs.

    What are Medicare Advantage plans required to cover?

    At a minimum, every Medicare Advantage plan sold in Montana must cover all of the benefits offered in Original Medicare. However, plans are not required to cover healthcare services in the same way. Medicare Part A covers 80% of hospital stays, skilled nursing, home health care, and hospice care. Part B covers 80% of doctor visits, lab tests, and other outpatient services. But, Medicare Advantage plans can set their own copays, and often charge more than 20%. On the positive side, plans must set an annual out-of-pocket limit.
