What is a Medicare Advantage plan in Great Falls?

Medicare Advantage plans, also known as Medicare Part C, offer an alternative to Original Medicare. These plans are legally required to provide the same coverage as Original Medicare but often include additional routine benefits, such as dental, hearing, and vision care, as well as prescription drug coverage and over-the-counter allowances. 

HMO vs. PPO Plans in Cascade County

Choosing between an HMO and a PPO plan in Central Montana often depends on your location and how much flexibility you need when seeing specialists:

• PPO Plans (Preferred Provider Organization): Offered by major regional carriers like Humana and Blue Cross Blue Shield of Montana, PPO plans provide vital out-of-network flexibility. This is particularly advantageous for rural Cascade County residents living outside the Great Falls city limits who may need to cross county lines to access specific specialists or facilities without a direct referral.

• HMO Plans (Health Maintenance Organization): Offered by regional insurers such as PacificSource Medicare, HMO plans typically feature lower premiums and lower annual maximum out-of-pocket limits. However, they require strict adherence to local in-network providers, meaning your routine care must stay within a designated network of doctors and facilities.

Great Falls MAPD Plans and the 2026 Drug Cap

Medicare Advantage plans in Great Falls may be available as Medicare Advantage Prescription Drug (MAPD) plans, which combine hospital, medical, and Part D drug benefits into one policy.

Under the Inflation Reduction Act, these plans include valuable cost-protection safeguards on covered prescription medications:

• 2026 Part D Out-of-Pocket Cap: Your annual out-of-pocket spending on covered prescription drugs is strictly capped at $2,100.

• 2027 Projected Cap Increase: Beneficiaries should note that the Part D out-of-pocket maximum is projected to rise to $2,400 in 2027.

Keeping these thresholds in mind is helpful when reviewing your annual medication expenses during the Annual Enrollment Period (AEP).

Local Healthcare Networks: Benefis Health System and Great Falls Clinic

A Medicare Advantage plan is only as effective as the doctor and hospital network attached to it. Before enrolling in any HMO or PPO plan, verify that your preferred healthcare facilities and medical groups are contracted in-network with the carrier.

In Cascade County, healthcare delivery revolves around a few major systems:

• Benefis Health System: Incorporating Benefis Hospitals Inc. and Benefis Community Care, this system supports acute, specialized, and long-term care in Great Falls.

• Great Falls Clinic: This network, which includes the Great Falls Clinic Hospital, offers outpatient services, primary care, and specialty centers.

Because some local HMO networks may partner primarily with one hospital system rather than another, confirming that your primary care physicians, preferred specialists, and local hospitals participate in the plan's network will help you avoid unexpected out-of-network costs.

Medicare Enrollment Periods

Great Falls beneficiaries can enroll in or switch Medicare Advantage plans coverage during specific windows:

• Initial Enrollment Period (IEP): A seven-month window surrounding your 65th birthday (three months before, the month of, and three months after).

• Annual Enrollment Period (AEP): Runs from October 15 to December 7 each year. Changes made during AEP take effect on January 1.

• Medicare Advantage Open Enrollment Period (OEP): Runs from January 1 to March 31. If you are already enrolled in a Medicare Advantage plan, you can switch to a different MA plan or drop back to Original Medicare during this period.

• Special Enrollment Periods (SEP): Available year-round when qualifying life events occur, such as moving out of Cascade County or qualifying for Medicaid.

Great Falls Medigap Plans: Coverage Beyond Local HMOs 

While we can help you check your enrollment eligibility and compare Medicare Advantage plans that may be available in Great Falls, we also may be able to help you find and compare available Medicare Supplement plans and Prescription Drug plans (Part D).

Medicare Supplement plans, also known as Medigap plans, help cover gaps in coverage from Medicare Part A and Part B, such as deductibles, coinsurance, and copayments. In most states, there are ten Medicare Supplement plans to choose from, and all policies have been standardized, meaning there’s no difference in the benefits offered between Medicare Supplement insurers.

Medicare Prescription Drug plans, also known as Medicare Part D, help cover the cost of both generic and brand-name medications. If you are already enrolled in Original Medicare (Part A and Part B), enrolling in a prescription drug plan will give you broader healthcare coverage and may even save you money. A Medicare Part D plan can be purchased as a standalone plan to supplement Original Medicare or to accompany a Medicare Supplement plan.
