Healthcare Cost Management: A Practical Guide for HR and Benefits Leaders
When an employee can’t afford their medication, or delays care because of a high deductible, that’s not just a benefits problem; it’s a people problem. HR and benefits leaders know this better than anyone. They’re the ones fielding the calls when a claim gets denied, explaining why premiums went up again, and trying to stretch a finite budget across a workforce with real, complex health needs.
HRMs sit at the intersection of fiscal responsibility and employee well-being, an increasingly difficult place to stand. Costs are rising at a pace not seen in over a decade, driven by specialty drugs, provider consolidation, and an aging workforce. And the plan design decisions that leaders make have real consequences for real people.
This guide is designed to give HR professionals, benefits managers, and plan administrators a clear-eyed view of where healthcare costs come from, which management strategies are working, and how the right tools and plan design decisions can make a meaningful difference without forcing a choice between fiscal responsibility and employee wellbeing.
Key Takeaways
- 2025 marks the third consecutive year of health benefit cost increases above 5%, following a decade of ~3% annual growth (Mercer).
- Prescription drug spend is the fastest-growing cost component, rising 7.2% per employee in 2024, driven by specialty drugs and GLP-1 medications.
Healthcare cost management is about smarter plan design, better data, and steering members toward higher-value care.
The State of Employer Healthcare Costs in 2025
To manage healthcare costs effectively, HR leaders need to understand the full scope of the challenge. The numbers tell a challenging story.
Key benchmarks from 2024–2025 employer surveys:
Average annual premium for family coverage: $26,993 (KFF 2025 Employer Health Benefits Survey)
Average cost per employee (employer + employee combined): $16,000+ in 2025 (Aon)
Share of employers making cost-cutting plan changes in 2025: 53%, up from 44% in 2024 Projected health benefit cost increase per employee in 2025: 5.8% after plan changes; ~7% without action (Mercer)
For smaller employers, the pressure is even more acute. Organizations with less negotiating leverage and fewer administrative resources tend to feel cost increases more sharply than their larger counterparts. Without proactive changes to plan design, those increases can compound quickly and become difficult to absorb.
The good news is that employers who take a data-informed approach to plan design can meaningfully reduce their cost trajectory. Targeted interventions can make a real dent in projected increases, even for organizations with limited resources.
What’s Driving Healthcare Costs? Understanding the Key Cost Drivers
Effective healthcare cost management starts with understanding what’s driving spend in your plan. Costs aren’t monolithic; they result from a mix of utilization patterns, drug pricing, provider contracts, and member behaviors. HR leaders who can identify which cost drivers are most relevant to their population are better positioned to target their interventions.
Prescription Drug Spend: The Fastest-Growing Category
Pharmacy is now the fastest-growing part of employer health benefit costs, and it deserves dedicated attention in any cost-management strategy. Drug benefit cost increases have been driven by:
- Specialty drugs for complex conditions like cancer, autoimmune diseases, and rare genetic disorders
- GLP-1 medications for obesity and diabetes, now covered by the vast majority of employers, but carrying significant per-patient price tags
- Gene and cell therapies, which are increasingly moving from clinical trials to standard of care for conditions that previously had no treatment options
Managing pharmacy spend requires formulary intelligence, utilization management, biosimilar adoption strategies, and the ability to model the cost impact of coverage decisions before you make them.
Provider Consolidation and Network Pricing
As health systems consolidate, employers lose negotiating leverage. Larger health systems command higher reimbursement rates and price transparency requirements, while designed to help, have had the unintended effect of enabling providers to benchmark their rates upward against higher-paying competitors. Network design and value-based contracting are increasingly important tools for combating this trend.
Chronic Conditions and High-Cost Claimants
A small percentage of plan members typically drive a disproportionate share of total claims. Cancer remains the top condition driving employer costs, followed by cardiovascular disease, musculoskeletal conditions, and diabetes. Identifying and supporting high-risk members through disease management programs before their conditions escalate to more expensive interventions is one of the most impactful long-term cost management strategies available.
Healthcare Cost Management Strategies That Actually Work
There is no single lever that controls healthcare costs. Effective management requires a layered strategy that addresses multiple cost drivers simultaneously. The table below summarizes the most commonly used approaches, who they’re best suited for, and their relative impact.
| Strategy | Best For | Typical Savings Potential | Implementation Complexity |
|---|---|---|---|
| Formulary optimization/biosimilars | All employer sizes | 15–50% on biologic spend | Low–Medium |
| High-deductible health plans (HDHPs) + HSAs | Cost-conscious workforces | 5–15% plan cost reduction | Low |
| Centers of Excellence (COEs) | Large employers with complex case volume | 20–30% on high-cost procedures | Medium |
| Preventive care & chronic disease management | Long-term cost reduction focus | Varies; long-term ROI | Medium |
| Step therapy protocols | Plans with high specialty drug spend | 10–30% on specialty Rx | Medium |
| Self-funded / level-funded plans | Mid-to-large employers | 10–20% vs. fully insured | High |
1. Formulary Optimization and Biosimilar Adoption
For employers with significant biologic drug spend, formulary optimization is one of the highest-ROI interventions available. Biosimilars deliver the same clinical outcomes as their reference biologics but typically cost 15–50% less at launch, with prices continuing to decline as more competitors enter the market.
In 2024, biosimilars generated $20.2 billion in savings for the U.S. healthcare system. For plan sponsors, the opportunity lies in ensuring those savings actually flow to the plan and its members, which requires smart formulary design and a PBM platform that automatically surfaces substitution opportunities.
2. High-Deductible Health Plans Paired with HSAs
HDHPs shift more initial cost-sharing to employees, which tends to reduce overall utilization of both appropriate and inappropriate care. When paired with employer-funded Health Savings Accounts (HSAs), they can be an effective cost-management tool while maintaining employee financial protection. However, HDHP design must be thoughtful. Research consistently shows that high cost-sharing can deter members from seeking necessary preventive care, which increases long-term costs. The goal is to reduce unnecessary utilization, not necessary care.
3. Centers of Excellence for High-Cost Procedures
Centers of Excellence programs direct employees to specialized, high-quality providers for complex procedures, including cancer treatment, cardiac surgery, joint replacements, and transplants.
COEs typically negotiate bundled payment arrangements that reduce total episode costs while simultaneously improving outcomes. For large employers with sufficient volume to justify the program, COEs are among the most compelling value-based care investments.
4. Preventive Care and Chronic Disease Management
Prevention is cheaper than treatment. This is not a new insight, but it remains underutilized as a cost management strategy. Employers who invest in preventive care programs, health screenings, and chronic disease management tools see returns as high-risk members are identified earlier and managed more effectively.
Behavioral health is a growing part of this equation: more employers identified improving mental health access as a top priority, recognizing its downstream impact on physical health costs.
5. Step Therapy Protocols
Step therapy requires that members try lower-cost, clinically appropriate medications before moving to more expensive alternatives. When applied thoughtfully (with appropriate exception processes for members with documented clinical needs), step therapy can reduce specialty drug spend without compromising clinical outcomes.
Effective step therapy requires robust prior authorization workflows and real-time clinical decision support — capabilities that should be built into your PBM platform.
H3: 6. Self-Funded and Level-Funded Plan Structures
Moving from a fully insured plan to a self-funded or level-funded model gives employers direct visibility into claims data and direct access to the savings when utilization is lower than expected. Self-funded plans also offer more flexibility in plan design, network selection, and vendor choice.
For mid-to-large employers, the shift to self-funding is often among the most significant structural cost-management moves available. However, it requires sophisticated administration and stop-loss coverage to manage the risk of catastrophic claims.
The Role of Data in Managing Healthcare Costs
Healthcare cost management is fundamentally a data problem. Employers who can see what’s driving their spend are in a fundamentally better position to act on it than those who are managing only aggregated numbers.
Best-in-class plan sponsors use data to:
- Identify high-risk members before they become high-cost claimants, enabling proactive outreach and disease management enrollment
- Benchmark provider performance on cost and quality to inform network design and COE program development
- Model formulary changes and project their cost impact before implementation
- Track biosimilar adoption rates and identify substitution opportunities across the member population
- Measure the ROI of wellness programs and point solutions to make evidence-based vendor decisions
The challenge for many HR teams is that this data is fragmented across carriers, PBMs, and third-party vendors, making it difficult to get a unified view of plan performance. Integrated PBM software that consolidates pharmacy and medical data in a single platform is increasingly a competitive advantage for plan sponsors serious about cost management.
Balancing Healthcare Cost Management with Employee Experience
There is an inherent tension in employer healthcare cost management: the strategies that reduce plan costs most aggressively also tend to reduce the employee experience and can create affordability barriers for lower-wage workers.
HR leaders navigating this tension should consider:
- Protecting preventive care access. Cost-sharing for preventive services tends to reduce utilization, thereby increasing long-term costs. HDHPs paired with HSA contributions can offset this risk.
- Tiering rather than eliminating. Formulary tiers and network tiers give members choices while creating financial incentives toward higher-value options, a more sustainable approach than blunt coverage restrictions.
- Communicating changes clearly. Members who understand why changes are being made are less likely to perceive them as punitive.
- Investing in navigation tools. Health advocacy and navigation services help members find the right care, at the right cost, at the right time. They reduce inappropriate utilization while improving member satisfaction.
- Monitoring health equity impacts. Cost management strategies can have disproportionate impacts on lower-income employees. Proactively reviewing plan changes through a health equity lens helps avoid unintended consequences.
Employers who manage this balance well tend to approach cost management as a quality improvement initiative. The goal is to reduce waste and inappropriate care, not to create barriers to necessary care.
