The Specialty Drug Problem
Specialty drugs — biologics, cancer drugs, and rare disease treatments — represent 50–60% of pharmacy costs despite only 1–2% of prescriptions. A single specialty drug claim can cost $100,000–$500,000 per year. Managing specialty drug costs is the single most important pharmacy cost management opportunity for most employer plans.
The Actionability Advantage
IQ Insight
The pharmacy benefit is the most actionable cost management opportunity in employer health plans. Unlike medical costs — which are driven by complex clinical decisions — pharmacy costs are highly manageable through formulary design, PBM contract terms, specialty drug management, and biosimilar adoption. Employers who actively manage their pharmacy benefit can reduce costs by 15–30% compared to passive management.
