Which statement about drug utilization management (UM) rules is false?

The statement that members can get medication with UM rules is accurate but can be misleading when interpreted in the context of the other options. Drug utilization management (UM) rules are designed to ensure that medications prescribed to patients are appropriate and cost-effective. These rules often involve processes such as prior authorization, where a healthcare provider must obtain approval from the insurance company before the medication can be dispensed.

Therefore, while it is true that members can ultimately receive their medications, they may need to go through certain protocols, such as meeting specific criteria or obtaining prior authorization. Medications that do fall under UM rules are typically assessed to ensure that they are necessary and cost-effective given the patient's particular health situation.

In the context of this question, "all medications fall under UM rules" is not true, as only certain medications are subjected to these management processes, meaning the statement about members receiving medications without any constraints under UM rules is indeed misleading and, in this case, the correct choice as being falsely representative of how UM operates.
