Answer: (A)

In a formulary, a tier system classifies drugs into levels that determine patient cost-sharing. Typically there are three to five levels, with lower tiers covering generics or preferred brand-name drugs at smaller copays, middle tiers covering other preferred brands, and higher tiers including non-formulary or specialty drugs with higher copays or coinsurance. This structure guides patients toward cost-effective options while giving clear expectations about out-of-pocket costs, and it helps formulary managers balance access with cost control. MAC stands for a price ceiling used by payers to reimburse multisource generics, limiting how much can be paid for those drugs. ASP, or Average Sales Price, is a reimbursement metric used mainly for Medicare Part B, reflecting the average price charged to purchasers. AAC, or Average Acquisition Cost, represents the average price a pharmacy pays to acquire a drug. These concepts relate to reimbursement or pricing methods rather than the way a formulary is tiered.
