Which of the following is NOT classified as marketing misrepresentation?

Using the beneficiary's P.O. Box as a mailing address does not constitute marketing misrepresentation because it does not involve providing false or misleading information about the plan or its benefits. A P.O. Box is simply an alternative mailing address and does not impact the accuracy of the information being conveyed to the beneficiary regarding coverage or eligibility.

In contrast, the other options involve active deception or misleading statements regarding the Medicare Advantage or Part D plans. Falsifying information about coverage, offering services that are not actually available, and misleading clients about eligibility criteria directly misrepresent the plans and can lead beneficiaries to make decisions based on incorrect or incomplete information. This highlights the importance of ensuring that beneficiaries receive accurate and truthful information to make informed choices.
