Pharmacy Benefits Strategy
PBM Consulting
Your PBM contract is one of the most consequential documents in your health plan. Most employers sign it without reading it — and pay for that mistake for years.
What It Is
A pharmacy benefit manager (PBM) is the intermediary between your health plan, drug manufacturers, and pharmacies. PBMs process prescription claims, negotiate drug prices, manage formularies, and collect rebates from manufacturers.
The problem is that PBMs operate with significant opacity. The same entity that negotiates on your behalf also profits from the spread between what it charges your plan and what it pays pharmacies — a conflict of interest that costs employers billions annually.
A transparent PBM arrangement eliminates spread pricing, passes 100% of manufacturer rebates to the plan, and includes audit rights so you can verify every dollar. Getting there requires understanding your current contract, knowing what to demand, and having the leverage — or a consultant with leverage — to negotiate it.
For self-funded employers, the PBM contract is often the single highest-leverage document in the entire health plan. Renegotiating it with the right terms can generate savings that dwarf any other cost-containment initiative.
Key Concepts
How PBM Contracts Work
What Is a PBM?
A pharmacy benefit manager administers prescription drug benefits on behalf of health plans. PBMs negotiate drug prices with manufacturers and pharmacies, manage formularies, and process claims.
Spread Pricing
The difference between what a PBM charges the plan and what it pays the pharmacy. Spread pricing is a primary source of PBM profit — and a primary source of employer overpayment.
Rebate Pass-Through
Drug manufacturers pay rebates to PBMs for formulary placement. In a transparent contract, 100% of rebates flow to the plan. In opaque contracts, the PBM retains a portion.
Formulary Design
The formulary determines which drugs are covered and at what tier. PBMs can steer members toward higher-rebate drugs regardless of clinical appropriateness or cost.
Specialty Drug Management
Specialty drugs represent 50%+ of pharmacy spend for many plans. Specialty carve-out arrangements and site-of-care management can generate significant savings.
Contract Audit Rights
Transparent PBM contracts include audit rights allowing the plan to verify pricing, rebates, and claims data. Without audit rights, you cannot confirm you're getting what you paid for.
Why It Matters
Why It Matters for Employers
"Pharmacy spend is the fastest-growing cost driver in employer health plans — often 25–35% of total plan cost."
"Employers who renegotiate PBM contracts with full pass-through and audit rights routinely save 15–25% on pharmacy spend."
"Most PBM contracts auto-renew with minimal notice. Missing the window locks you in for another multi-year term."
Common Pitfalls
Common Mistakes to Avoid
- 1
Signing a multi-year PBM contract without independent legal or consulting review.

Accepting a rebate guarantee without understanding what drugs are included and how rebates are calculated.
- 3
Failing to require 100% pass-through of manufacturer rebates and pharmacy spread.
- 4
Not tracking specialty drug utilization and site-of-care costs separately from retail pharmacy.
