Employer health plan benchmarking has become a standard part of benefits strategy. Reports from consultants, carriers, and industry groups promise to show how a plan compares to “peers” on cost, utilization, and design. On the surface, this seems like a rational approach to cost control.
But benchmarking can create a false sense of security.
In an environment where healthcare costs are rising across the board, being “in line with the market” does not necessarily mean a plan is efficient, well-governed, or financially optimized. In many cases, benchmarking reinforces cost inflation rather than controlling it. The result is a structural risk for employers: plans that appear competitive on paper but are quietly accumulating avoidable cost.
Why benchmarking feels reliable — and where it breaks down
Benchmarking works best when variation reflects performance differences. In healthcare, that assumption is often flawed.
PwC notes in its Health Research Institute reports that medical cost trends are projected to remain elevated, with underlying drivers including price increases, higher utilization of specialty services, and shifts in site of care. When the entire market is trending upward, benchmarking becomes a comparison against a rising baseline, not a measure of efficiency.
Similarly, the Kaiser Family Foundation (KFF) consistently reports steady growth in employer-sponsored health insurance premiums, with family coverage costs increasing significantly over time. These increases are systemic, not isolated.
This creates a core problem: if peer plans are experiencing the same inefficiencies — unit price variation, unmanaged utilization, opaque contracting — benchmarking simply normalizes those issues.
The illusion of “market competitiveness”
A plan can benchmark well and still overspend.
For example:
- Two employers may both pay similar amounts for imaging
- Both may align with regional benchmarks
- But one may route care to hospital outpatient departments while the other uses lower-cost ambulatory centers
Benchmarking does not distinguish between those scenarios.
Health Care Cost Institute data show that prices for the same services can vary dramatically across providers and sites of care, even within the same geographic area. These variations are often unrelated to quality.
In other words, benchmarking averages hide operational differences that materially impact cost.
Where hidden inefficiencies accumulate
1. Unit price variation
Healthcare pricing is not standardized. Employers often pay vastly different rates for identical services depending on network contracts and provider negotiations.
RAND Corporation studies have found that employer-sponsored plans frequently pay multiples of Medicare rates for the same hospital services, with wide variation across systems. Benchmarking does not correct these disparities — it simply reports where those disparities sit relative to peers.
2. Site-of-care misalignment
One of the most significant and least managed cost drivers is where care is delivered. Hospital outpatient departments routinely charge significantly more than independent facilities for the same services.
Research published in the Journal of Managed Care & Specialty Pharmacy and summarized by Elevance Health shows that infusion therapies performed in hospital outpatient settings can cost over 40% more than in alternative sites, with comparable clinical outcomes. Benchmarking does not capture whether a plan is actively steering care to efficient settings — only whether its total cost aligns with others.
3. Utilization management gaps
Benchmarking focuses on outcomes (cost per member), not the processes that drive them.
Milliman highlights that variation in utilization — including unnecessary imaging, avoidable procedures, and inconsistent adherence to clinical pathways — is a major contributor to cost differences across plans. Without disciplined prior authorization, step therapy, and exception governance, utilization can drift upward even while benchmarks appear stable.
4. Contracting opacity and financial leakage
Many employers rely on summary reporting from carriers or PBMs without full visibility into underlying economics.
The Federal Trade Commission has documented how vertical integration and opaque pricing structures in healthcare — particularly in pharmacy — can obscure true net costs and shift revenue across affiliated entities. Benchmarking does not account for spread pricing, retained rebates, administrative fees embedded in claims, or channel steering to affiliated providers. A plan may benchmark well while still leaking value through its contracts.
The governance gap: what benchmarking leaves out
Benchmarking is descriptive, not operational.
It answers:
- What are others spending?
It does not answer:
- Why are we spending this amount?
- Was the service necessary?
- Was it delivered at the right price and location?
- Did the plan design guide the right behavior?
Deloitte emphasizes that leading employers are shifting from passive benchmarking to active health plan management, focusing on data transparency, care navigation, and value-based design. This reflects a broader industry shift: from comparison to control.
A more effective framework for employers
To move beyond benchmarking, employers need a governance-based approach to health plan management.
1. Establish price transparency and auditability
Employers should require:
- Claim-level data access
- Clear definitions of allowed amounts and fees
- Visibility into provider reimbursement structures
- Audit rights to validate contract performance
The goal is understanding true net cost, not just reported averages.
2. Actively manage site of care
Plans should:
- Identify high-cost service categories (imaging, infusions, surgeries)
- Implement site-of-care steering through prior authorization
- Align incentives for members to choose efficient settings
This is one of the most immediate and measurable cost controls available.
3. Strengthen utilization governance
A disciplined framework includes:
- Evidence-based prior authorization
- Step therapy protocols where appropriate
- Structured exception review processes
- Ongoing monitoring of approval and denial patterns
The objective is consistency — ensuring that plan rules are applied as designed.
4. Evaluate contracts beyond headline discounts
Employers should move past:
- Discount percentages
- Benchmark comparisons
- Renewal guarantees
And instead evaluate:
- Total cost of care
- Financial flows across vendors
- Alignment between contract terms and actual claims outcomes
5. Measure operational performance, not just cost
More meaningful metrics include:
- Cost per service by site of care
- Utilization rates for high-cost categories
- Variation across providers
- Exception frequency and outcomes
- Net cost trends after all fees and adjustments
These metrics create accountability — something benchmarking alone cannot provide.
Conclusion
Benchmarking is not inherently flawed, but it is incomplete. In a healthcare system where costs are rising broadly and inefficiencies are widely shared, benchmarking can create the illusion of control while masking underlying issues.
Employers who rely on it as a primary strategy risk accepting inflated costs as “normal.” The more effective approach is governance. By focusing on transparency, utilization discipline, site-of-care management, and contract accountability, employers can move from passive comparison to active cost control.
The difference is not subtle: it is the difference between tracking the market and managing it.
