Key Takeaways

• Medicare Advantage plans vary significantly across states, including differences in provider networks, supplemental benefits, and availability. What works well in one state may not be available or effective in another.

• The CMS Star Rating helps compare plan quality, but it does not reflect local variations in access, coverage, or cost-sharing that are critical to your personal experience.

Medicare Advantage: One Label, Many Local Versions

Medicare Advantage plans, also known as Medicare Part C, are marketed as alternatives to Original Medicare. They are required to offer at least the same level of coverage as Parts A and B, but the similarities often end there. These plans are operated by private companies approved by Medicare and are offered on a regional basis. That means no two plans are exactly alike across different states—and assuming they are can lead to costly mistakes.

What you get under a Medicare Advantage plan in Florida could be entirely different from what someone else gets under the same plan name in Oregon. These differences affect everything from doctor availability to drug costs.

What Makes These Plans So Region-Specific?

There are several reasons Medicare Advantage plans operate differently in each state:

Provider Networks Are Localized

Plans build their provider networks based on local contracts with hospitals, physicians, and specialists. That means the same plan in two neighboring states might have vastly different access to care. A plan with an extensive network in Texas may have limited reach in Nebraska.

If you move or travel frequently, especially across state lines, this variability can become a serious concern. Unlike Original Medicare, which is nationally accepted, most Medicare Advantage plans only cover non-emergency services within their network region.

Supplemental Benefits Are Optional and Vary by Area

Many Medicare Advantage plans offer benefits that go beyond Original Medicare, such as:

• Vision and dental coverage

• Hearing aids

• Fitness programs

• Transportation to medical appointments

But these extras are not standardized. A plan in one region may include all these perks, while another version of the same plan may offer only a few or none. Local market competition, enrollee demand, and provider availability all influence which extras get included.

Prescription Drug Coverage (Part D) Varies by Plan and State

Most Medicare Advantage plans include Part D coverage. However, drug formularies (lists of covered medications), pharmacy networks, and tiered pricing vary not just by plan but also by state. A medication that is affordable in one plan version may be far more expensive in another state, even if the plan names are identical.

Cost Structures Are Not the Same Everywhere

General costs under Medicare Advantage plans can include:

• Monthly premiums (in addition to the Part B premium)

• Deductibles

• Copayments and coinsurance

• Out-of-pocket maximums

While these cost elements exist nationwide, the exact amounts vary by location. For example, a plan might have lower copayments in rural areas to compete with limited provider access, but higher costs in urban areas where more choices exist.

Understanding the CMS Star Rating and Its Limits

The Centers for Medicare & Medicaid Services (CMS) issues a Star Rating every year to help you evaluate Medicare Advantage plans. Ratings range from 1 to 5 stars and assess:

• Chronic condition management

• Preventive care access

• Customer service

• Member complaints and appeals

While helpful, the CMS rating system does not tell the whole story. A 5-star plan in one region could perform very differently in another. Local execution, provider partnerships, and community health resources all shape your actual experience.

You should use CMS ratings as a starting point but dig deeper into:

• Regional network size and quality

• Prescription drug coverage specifics

• Customer reviews from your own area

• Availability of supplemental benefits

Why the Plan with the Best Rating May Not Be the Best for You

In 2025, more plans than ever advertise 4- or 5-star ratings. However, that rating might reflect excellent preventive care and customer service in one state and below-average provider access in another. You need to go beyond star ratings to assess what works for you, especially if:

• You live in a rural area with fewer providers

• You require regular specialist visits

• You take multiple prescription drugs

• You split your time between two states

The Impact of State-Specific Rules and Approvals

Even though Medicare is a federal program, states influence how Medicare Advantage plans are administered. Each plan must be approved by CMS for sale in specific counties or service areas. States also play a role in Medicaid coordination, which matters if you’re dual eligible.

In some states, additional state insurance rules may impact:

• Marketing practices

• Enrollment periods

• Plan offerings and availability

What this means for you is simple: your options are shaped not just by Medicare rules but also by state-level dynamics.

Timing and Enrollment Considerations Vary Too

Medicare Advantage enrollment periods are consistent nationwide, but timing matters more depending on where you live.

• Initial Enrollment Period (IEP): Begins 3 months before the month you turn 65 and ends 3 months after.

• Annual Enrollment Period (AEP): October 15 to December 7 every year.

• Medicare Advantage Open Enrollment Period: January 1 to March 31 each year. You can switch plans or go back to Original Medicare.

However, in some states, Special Enrollment Periods (SEPs) may be more commonly triggered by local events, such as natural disasters or plan exits. You must be aware of state-specific triggers for plan changes.

What If You Move to Another State?

Relocation is a major life change that can trigger a Special Enrollment Period. But it’s not just about updating your address. Medicare Advantage plans do not usually transfer from one state to another.

If you move, you generally have 2 full months to:

• Select a new Medicare Advantage plan available in your new location

• Return to Original Medicare and choose a standalone Part D plan

Failing to act within this window could leave you temporarily without comprehensive coverage. That’s why it’s critical to research plans in your destination state before the move.

Tips for Choosing the Right Plan in Your State

If you’re evaluating Medicare Advantage plans in 2025, keep these steps in mind:

• Start with the CMS Plan Finder Tool: But don’t stop there.

• Review local provider directories: Check that your doctors and hospitals are in-network.

• Compare drug formularies: Ensure your prescriptions are covered affordably.

• Understand all out-of-pocket costs: Not just premiums, but also copays, coinsurance, and deductibles.

• Ask about supplemental benefits: These vary widely by location.

• Review plan rules for referrals and authorizations: These can restrict your access to care.

Why State-Specific Evaluation Matters in 2025

Plan offerings change every year. In 2025, some states have seen consolidation of plans, while others have seen new entries. You may notice changes in:

• Availability of Special Needs Plans (SNPs)

• Changes in provider networks

• Removal or addition of popular supplemental benefits

With these shifts, reviewing your plan annually isn’t optional. It’s essential.

Looking Beyond the Surface Before You Choose

Medicare Advantage plans may sound similar nationwide, but they are deeply rooted in local conditions. Benefits, costs, and provider access vary based on where you live. Relying on star ratings or national rankings without examining your specific state’s options could result in unexpected limitations or higher costs.
