Hidden PBM fees; such as spread pricing and opaque rebate structures, often inflate employer healthcare costs. By demanding pass-through pricing and securing audit rights in your PBM contract, employers can gain transparency, reduce waste, and achieve measurable healthcare cost savings.
Introduction
Prescription drug spending is one of the largest drivers of rising healthcare costs for employers. Yet much of that spend is clouded by PBM fees and complex pricing models that are hard to decode. According to recent industry reports, spread pricing by PBMs can add up to 30% in hidden costs—dollars that could otherwise go toward patient care or organizational savings.
I help employers cut through this complexity. This guide explains how hidden PBM fees work, why spread pricing persists, and how pass-through pricing combined with audit rights can protect your organization’s bottom line.
What Are PBM Fees and Spread Pricing?
A Pharmacy Benefit Manager (PBM) negotiates drug prices between manufacturers, pharmacies, and employers. While PBMs are meant to reduce costs, their contracts often include hidden fees.
- Spread Pricing: The PBM charges the employer more for a drug than it reimburses the pharmacy, keeping the difference as profit.
- Administrative Fees: Layered costs that may not be clearly disclosed.
- Rebate Retention: PBMs may retain a portion of manufacturer rebates instead of passing them to employers.
These hidden fees make it nearly impossible for employers to know the true cost of their pharmacy benefits.
Why Hidden PBM Fees Are a Problem
- Lack of Transparency: Employers don’t see the actual acquisition cost of medications.
- Unnecessary Spending: Spread pricing alone can inflate costs by millions annually.
- Employee Impact: Higher costs can shift to employees through copays or premiums.
- Compliance Concerns: Opaque contracts may limit employers’ ability to ensure fiduciary responsibility.

Step-by-Step: Eliminating Hidden PBM Fees
Step 1: Demand Pass-Through Pricing
Pass-through pricing means the employer pays the exact price the PBM negotiates, with no hidden markup. Employers then pay the PBM only a clear, administrative fee.
Step 2: Secure Strong Audit Rights
Audit clauses allow employers to verify PBM performance, rebate flows, and compliance. Without audit rights, employers must trust the PBM’s reporting.
Step 3: Benchmark Your Contract
Compare your PBM Contract against industry standards to uncover hidden spreads and unnecessary charges.
Step 4: Monitor Specialty Drug Spending
Specialty medications now account for over 50% of total pharmacy costs. Employers should ensure their PBM contract provides transparency and management tools specific to specialty drugs.
Step 5: Partner with Experts
Third-party advisors can help interpret complex PBM contracts, identify hidden clauses, and negotiate more favorable terms.

Common Misconceptions About PBM Contracts
- “All PBMs operate the same way.” False. Some PBMs now offer transparent, pass-through models.
- “Audit rights are optional.” False. Without them, employers cannot validate cost savings.
- “Rebates always reduce costs.” Not always—retained rebates may inflate drug list prices.
Industry Insight: The Push Toward Transparency
In 2025, more employers are demanding pass-through PBMs, and legislation is being introduced to regulate spread pricing. The shift is clear: transparency is becoming the new industry standard.
