The Top 3 Healthcare Cost Drivers in the Midwest (and What Employers Need to Do About Them)

 

Across the Midwest, employers are seeing a consistent pattern emerge. A small percentage of members are driving a disproportionate share of total healthcare spend, while broader, high-frequency conditions continue to add pressure across the entire population.

In fact, it’s common for just 5% of members to account for nearly 50% of total healthcare costs.

So what’s driving this trend?

The 3 Biggest Healthcare Cost Drivers in the Midwest

Over the past 12 months, three categories have stood out as the primary drivers of employer healthcare spend:

1. Cancer Treatment and High-Cost Care Events

While not the most frequent condition, cancer remains one of the most expensive.

Treatment often involves:

  • Complex care plans

  • Extended treatment timelines

  • High-cost specialty medications

These cases represent catastrophic claims that can significantly impact a health plan in a short period of time.

But cancer is only one piece of the puzzle.

2. Musculoskeletal (MSK) Conditions

Musculoskeletal conditions—such as back pain, arthritis, and joint issues—are among the most common and costly conditions for employers.

These costs are largely driven by:

  • High utilization of outpatient services

  • Physical therapy and ongoing treatment

  • Imaging and surgical interventions

Because of their frequency, MSK conditions create a steady and ongoing cost burden across employee populations.

3. Endocrine Conditions (Including Diabetes)

Endocrine disorders, particularly diabetes, are another major contributor to rising healthcare costs.

The biggest driver here? Long-term pharmacy spend.

This includes:

These conditions represent chronic, ongoing costs that build over time rather than spike all at once.

Where Healthcare Dollars Are Actually Going

Another important shift employers are seeing is where care is being delivered.

In the Midwest, a significant portion of healthcare spend is now concentrated in:

  • Outpatient care

  • Pharmacy

  • Specialty medications

While inpatient care still plays a role, more treatment is moving toward outpatient settings and drug-based therapies, which changes how costs accumulate and how they should be managed.

Why Healthcare Costs Are Rising

When employers ask, “Why are our healthcare costs increasing so dramatically?”—the answer isn’t simple.

It’s the result of balancing:

  • High-cost, low-frequency events (like cancer)

  • High-frequency conditions (like MSK issues)

  • Chronic conditions (like diabetes)

At the same time, more of this care is being delivered through:

  • Outpatient services

  • Specialty medications

  • Long-term treatment plans

Modern medicine is enabling better outcomes—but it’s also shifting costs into new and often more expensive areas.

How Employers Can Better Manage Healthcare Spend

To effectively manage healthcare costs, employers need to move beyond reactive solutions.

A successful strategy should address both ends of the spectrum:

1. Plan for Catastrophic Events

  • Evaluate stop-loss coverage

  • Identify high-cost claim management strategies

  • Ensure access to high-quality care pathways

2. Manage High-Frequency Conditions

  • Invest in musculoskeletal management programs

  • Guide employees to appropriate care settings

  • Reduce unnecessary utilization

3. Control Chronic Condition Costs

  • Implement diabetes management and prevention programs

  • Evaluate pharmacy strategies, including GLP-1 management

  • Improve medication adherence and outcomes

4. Optimize Outpatient and Pharmacy Spend

  • Review site-of-care strategies

  • Manage specialty drug utilization

  • Leverage data to identify cost drivers early

How Caravus Helps Employers Navigate Healthcare Costs

Healthcare costs in the Midwest aren’t rising because of one condition…they’re rising because of everything happening at once.

Employers who take a fragmented approach will continue to feel the pressure.

Those who build a connected, data-driven strategy across catastrophic, chronic, and high-frequency care will be better positioned to control costs and improve outcomes.

At Caravus, we help employers design smarter health plans that address the full picture of healthcare spend—from high-cost claims to everyday care management.

If you're looking to better understand your cost drivers and build a more effective strategy, we’re here to help.
