Why A is correct
CMS regulations require every Part D plan's formulary to include at least two drugs in each therapeutic category and class, so beneficiaries have a genuine choice of treatment within each disease area. Plans may use tiers and utilization management such as prior authorization and step therapy, but the two-drug minimum protects access. A formulary is not required to cover every FDA-approved drug, and plans routinely cover generic and brand products together. The two-drug-per-class minimum is the precise formulary standard tested in the Medicare Part D section of the senior health products outline.
Why the other options are wrong
- B) One drug per class is below the statutory minimum of two.
- C) Formularies include generics and brands; they are not brand-only.
- D) No plan covers every FDA-approved drug; formularies are selective by design.
