What action is required if a beneficiary wants to change their plan during the SEP?

When a beneficiary wishes to change their plan during a Special Enrollment Period (SEP), it is essential for the change to be documented properly. Documentation serves multiple purposes: it provides verification of the changes made, ensures that the beneficiary's new coverage starts without issues, and maintains a clear record of the beneficiary's plan modifications. Proper documentation is critical in the healthcare system to prevent any lapses in coverage and ensure that the changes align with the regulations governing Medicare Advantage plans.

Other options may involve steps in the process but do not address the fundamental requirement of having the change documented. Merely notifying a previous provider or reapplying for a new plan may not suffice without the necessary documentation in place. Submitting a disenrollment request can be part of the process but again highlights the need to have a documented record of the beneficiary's actions to ensure a smooth transition to the new plan. Therefore, documenting the change is the most crucial action required when a beneficiary decides to modify their healthcare coverage during an SEP.
