Prescription drug spending can be a significant part of an employer’s healthcare budget. Yet understanding what a health plan pays for medications, and whether those costs represent good value, isn’t always straightforward.
Specialty medications, complex pricing arrangements, rebates, and pharmacy benefit manager contracts can make it difficult to see the full picture.
For HR leaders, the goal is to balance affordability and appropriate access to medications while ensuring the organization’s pharmacy strategy is working as intended.
Three Pharmacy Cost Blind Spots to Watch
- Focusing on rebates instead of net costs – A pharmacy benefit manager (PBM) may negotiate rebates from drug manufacturers, but a large rebate doesn’t automatically mean the plan has the lowest overall costs.
- Employers should understand the difference between gross drug spending and net costs after applicable rebates and fees. Ask how the PBM is compensated, how rebates are handled, and whether the contract provides clear reporting and audit rights.
- Overlooking specialty medications – Specialty drugs can account for a substantial share of pharmacy spending, depending on the plan’s membership and treatment needs.
- Review which medications drive the highest costs, how specialty prescriptions are managed, and whether appropriate clinical support and cost-effective treatment settings are available. The objective is to support appropriate care, not simply reduce prescription use.
- Making coverage decisions without a clear strategy – GLP-1 medications and other high-cost therapies have brought new attention to pharmacy benefit decisions. Employers should understand which medications and indications are covered, what clinical criteria apply, and how coverage affects both plan costs and employee access.
- Coverage decisions should reflect the organization’s financial goals, workforce needs, and clinical considerations. Your benefits consultant and pharmacy advisors can help evaluate the available options.
Questions to Ask at Your Next Pharmacy Review
Before renewal, ask your benefits team or PBM:
- Do we understand our total pharmacy costs, including applicable rebates and fees?
- Which medications and categories are driving our spending?
- Are our contract terms, pricing guarantees, and reporting transparent?
- Are our specialty drug and GLP-1 coverage policies aligned with our goals?
- How are we measuring financial results and member outcomes throughout the year?
Regular reviews can help identify changing utilization patterns, assess contract performance, and uncover opportunities to improve value before the next renewal.
The Takeaway
Effective pharmacy management requires more than reviewing a spending report. Employers need transparency into their contracts, a clear understanding of what drives costs,
and a strategy that balances financial accountability with appropriate access to care.
The question isn’t just how much your organization spends on prescriptions. It’s whether you understand what you’re paying for, and what value your pharmacy benefit delivers.
