Pharmacy Benefit Design describes which concept?

• A. The layout of a pharmacy
• B. Structure of drug coverage, tiers, and cost-sharing rules
• C. The building's interior design
• D. Staffing levels in pharmacy

Answer: (B)

The concept being tested is how a health plan structures medication coverage, including how drugs are placed into formulary tiers, the cost-sharing rules (like copays and coinsurance), and management tools such as prior authorization or step therapy. This design determines what patients pay out-of-pocket, which drugs are preferred or covered, and how utilization is guided to balance access with cost containment. The other options describe the physical layout, interior design, or staffing of a pharmacy—areas that concern operations and facilities rather than the benefits design of medications.
