Which of the following is NOT a role of a health insurance exchange under the Affordable Care Act (ACA)?

The role of a health insurance exchange under the Affordable Care Act (ACA) is primarily to enhance consumer access to health insurance and to ensure that individuals can effectively understand and navigate their options. In this context, not contacting the employer if an employee stops coverage under a plan aligns with the correct answer.

Health insurance exchanges are designed to inform consumers about various health insurance options available to them. They provide critical information that helps individuals make informed decisions regarding their coverage. Additionally, exchanges assist individuals in determining their eligibility for financial subsidies, aimed at making health insurance more affordable. They also facilitate the enrollment process into different insurance plans, ensuring that the enrollment experience is user-friendly and efficient.

In contrast, contacting the employer when an employee stops coverage under a plan does not fall within the primary responsibilities of a health insurance exchange. The interactions regarding coverage changes typically occur directly between employers and employees or through the respective insurance providers, rather than through the exchange itself. Thus, this option is not a function of health insurance exchanges under the ACA.
