Two self-insured employers sent their PBM one email. The answers exposed $135,000 and $545,000 a year in revenue the plan never saw. Get the same 12 questions and see what your PBM says.

We audited the contracts behind both case studies. Different PBMs, different employer sizes, same three terms: the PBM keeps the manufacturer rebates, spread pricing is allowed, and there is a financial penalty for leaving early. None of it is illegal. The question for a plan fiduciary is simply: who does this benefit?

of all U.S. prescription claims are controlled by just three PBMs — leaving most employers with limited negotiating leverage and little visibility into true costs.
For many employers, pharmacy is no longer a side issue inside the health plan. It is becoming one of the fastest-growing and least transparent areas of cost.
Rising specialty drug utilization, rebate-driven pricing, and opaque PBM contract structures are creating more volatility and making it harder for employers to understand what they are truly paying.
For self-insured employers especially, that means pharmacy may be one of the largest unmanaged expenses in the plan.
Specialty drugs now make up a disproportionate share of pharmacy spend for many employers.
Rebate arrangements can incentivize PBMs to favor higher-cost drugs over clinically equivalent, lower-cost alternatives.
Many PBM contracts are written in ways that make it genuinely difficult for employers to audit true performance.
Pharmacy costs are now frequently the fastest-growing line item in self-insured health plans.
Many traditional PBM arrangements include contract terms and pricing structures that make it difficult to identify true savings. If you are only being shown discounts and rebates, you may not be seeing the full financial picture.
PBM compensation structures can reward volume and rebate capture rather than lowering your organization's net drug cost.
PBM contracts are often structured in ways that obscure the relationship between reported savings and actual spend changes.
When reporting centers on discounts and rebates rather than total cost trend, it becomes difficult to assess whether the plan is truly performing.
In some arrangements, PBMs charge employers more than they reimburse pharmacies — capturing the difference as undisclosed revenue.
Without active specialty management strategies, employers may face significant and unexpected cost increases driven by a small number of high-cost prescriptions.
Formularies that aren't actively managed may allow higher-cost branded drugs to be dispensed when clinically equivalent generics are available.
High-performing employers are taking a closer look at pharmacy and asking whether a more transparent model can deliver better alignment, greater control, and lower net cost.
A transparent pharmacy carve-out can help employers move away from opaque pricing structures and toward a model where incentives are aligned around reducing actual spend, not just producing favorable-looking reports.
See exactly what you're paying — ingredient cost, dispensing fees, and any margins — with no hidden spread pricing.
Work with a PBM model where success is measured by actual cost reduction — not rebate volume or network spread.
Own your own formulary and clinical programs — making decisions based on your population's needs, not the PBM's book of business.
The goal of a transparent carve-out is measurable, sustainable reduction in what you actually spend on pharmacy — not just better-looking reports.
This free resource is designed to help CFOs, HR leaders, and decision-makers better evaluate whether their current PBM arrangement is serving the organization well.

Pharmacy Benefits Unbundled is an educational resource from Eric Papp, a Tampa-based employee benefits consultant who works with self-insured employers with 500 to 5,000 employees.
His work centers on a question most plans have never asked out loud: what does the pharmacy benefit actually cost once you separate it from the medical plan? Eric is the author of Leadership by Choice (Wiley) and Manage Promises, Not People, and spoke on pharmacy carve-outs at SHRM’s 2026 national conference.
