Affordable Care Act (ACA) Marketplace Mental Health Coverage Guide

This starter guide covers the mental health benefits potentially available through the Affordable Care Act (ACA) Health Insurance Marketplace, as well as some of the initial questions to ask your insurance plan and how to find coverage for therapies that work for you and your family — whether you’re seeking care for yourself or a child.

What Is the Affordable Care Act (ACA) Marketplace?

The ACA is a United States federal law enacted in 2010 that expanded access to health insurance through the Health Insurance Marketplace. Under the ACA, health plans sold through the Marketplace must:

• Include mental health and substance use disorder benefits
• Apply mental health coverage at the same level as medical and surgical care under mental health parity protections

Most Marketplace plans include:

• Therapy
• Psychiatric care
• Medication coverage
• Behavioral health services

However, coverage details such as provider networks, prior authorization requirements, costs and deductibles, and out-of-network reimbursement can vary significantly by plan.

What are the eligibility requirements?

To enroll in health coverage through the Marketplace, you must:

• Live in the United States
• Be a United States citizen, United States national, or lawfully present non-citizen
• Not be incarcerated
• Not already enrolled in Medicare
