9. Spread Pricing: A Controversial PBM Practice

Spread pricing is a controversial practice used by some Pharmacy Benefit Managers (PBMs). It involves charging health plans more for drugs than they reimburse pharmacies, with the PBM pocketing the difference as profit. This practice has come under scrutiny due to concerns about transparency and potential conflicts of interest.

9.1. How Spread Pricing Works

In a spread pricing arrangement:

A pharmacy dispenses a prescription to a patient.
The pharmacy submits a claim to the PBM for reimbursement.
The PBM reimburses the pharmacy for the cost of the drug, plus a dispensing fee.
The PBM then charges the health plan a higher amount for the drug than it reimbursed the pharmacy, keeping the difference as profit.

For example, a PBM might reimburse a pharmacy $80 for a drug but charge the health plan $100, pocketing a $20 “spread.”

9.2. Concerns About Spread Pricing

Spread pricing has raised several concerns:

Lack of Transparency: Health plans may not be aware that PBMs are engaging in spread pricing, making it difficult to assess the true cost of prescription drug benefits.
Potential for Overcharging: Spread pricing can allow PBMs to overcharge health plans for drugs, increasing healthcare costs.
Conflicts of Interest: PBMs may be incentivized to favor pharmacies that accept lower reimbursement rates, allowing them to maximize their spread.
Impact on Independent Pharmacies: Spread pricing can put independent pharmacies at a disadvantage, as they may not be able to compete with larger chains that can afford to accept lower reimbursement rates.

9.3. Arguments in Favor of Spread Pricing

Some argue that spread pricing is a legitimate way for PBMs to generate revenue and that it helps to offset other costs. They also contend that health plans are sophisticated purchasers that can negotiate favorable terms with PBMs.

9.4. Efforts to Curb Spread Pricing
