Final answer:
If a health insurance plan receives an unsolicited enrollment application before AEP, it must review and process the application according to its established procedures.
Step-by-step explanation:
If a health insurance plan receives an unsolicited enrollment application prior to the Annual Enrollment Period (AEP), the plan must process the application according to their established procedures. This means that the plan cannot simply ignore the application, but rather they must review it and make a determination based on the information provided. The plan may accept or deny the application based on the eligibility criteria and enrollment rules.
