What is a requirement for Mrs. Parker if she wants to enroll by telephone?

For Mrs. Parker to enroll by telephone, the requirement that the call must be recorded is essential. This practice serves multiple purposes in the context of fraud, waste, and abuse prevention. Recording the call provides a verifiable record of the conversation, ensuring that both the applicant and the enrollment agent have a clear and legal account of what was discussed and agreed upon during the enrollment process.

The recordings can be reviewed later if there are any disputes or questions about the enrollment, ensuring compliance with regulations and protecting the interests of both parties involved. This requirement helps to maintain the integrity of the enrollment process and offers a layer of accountability, which is crucial in the prevention of potential fraudulent activities.
