What element typically triggers communication of changes to plan participants?

The correct answer is the changes in dependents or provider networks. This element is significant because any alterations in dependents covered under a benefit plan can have direct impacts on the resources and support that plan participants rely on. For instance, if a plan participant adds or removes a dependent from their coverage, they need to be informed about how this change affects their benefits, eligibility, and out-of-pocket expenses.

Similarly, changes in provider networks can significantly affect participants' access to healthcare services. If a participant's preferred provider is no longer in the network, it may lead to higher costs or a need to switch providers entirely. Therefore, communicating these changes is crucial to ensure that participants understand their options and can make informed decisions about their healthcare coverage.

While elements like increased marketing efforts, annual performance reports, and regular audits are important for overall plan management and communication, they do not typically trigger immediate and essential changes that require direct communication with plan participants to maintain clarity and ensure the continuity of care and benefits.
