Which activity might indicate an issue related to compliance that requires attention?

A late enrollment penalty dispute is an activity that may indicate a compliance issue requiring attention because it highlights potential problems with enrollment processes, member communication, or adherence to regulatory guidelines. Such disputes can suggest that members might not have received accurate information about their enrollment periods or requirements, which could lead to financial penalties for them and raise concerns regarding the organization's compliance with Medicare guidelines.

In contrast, positive customer feedback, successful marketing strategies, and increased membership generally indicate that an organization is performing well and meeting the needs of its constituents. These activities typically reflect successful operations rather than compliance issues. Therefore, the focus should be on resolving any disputes regarding late enrollment penalties to ensure compliance and improve member satisfaction.
