Which statements about drug utilization management (UM) rules are true?

• A. Prior authorization, quantity limit, and step therapy are examples of UM rules.
• B. UM rules only apply to hospital services.
• C. There are no utilization management rules in Medicare plans.
• D. UM rules always delay approval for all drugs.

Answer: (A)

Drug utilization management uses rules to guide how medications are approved and paid for, aiming to balance patient access with safety and cost control. The main tools include prior authorization, quantity limits, and step therapy. Prior authorization requires payer approval before a drug is covered, often used for high-cost or specialty medications. Quantity limits cap how much of a drug can be dispensed within a set period to prevent overuse or waste. Step therapy requires trying a preferred, typically lower-cost option before a nonpreferred one, ensuring cost-effective choices first.

These approaches aren’t limited to hospital settings; UM rules apply across various care environments, including outpatient and specialty drug use. Medicare plans also employ utilization management rules, with many Part D and Medicare Advantage plans using prior authorization, quantity limits, and step therapy to manage drug benefits. And UM does not inherently delay every drug—some approvals are straightforward when criteria are met, and in other cases the steps are necessary to ensure appropriate use.
