Behavioral health, meaning mental-health and substance-use care, is covered by most insurance plans in the United States, but the details determine what a person actually pays and where they can go. Knowing how coverage works makes it easier to get care approved and to avoid surprise bills.

This guide explains the basics of coverage and parity. It is informational only and not financial or medical advice. Confirm specifics with your own plan.

What parity means

The Mental Health Parity and Addiction Equity Act generally requires most health plans to cover mental-health and substance-use benefits at levels comparable to medical and surgical benefits. In practice, that affects things like visit limits, prior authorization, and how much you pay. A marketplace plan under the Affordable Care Act must also cover behavioral health as an essential health benefit.

Parity does not mean every service is free or every provider is included. It means the plan's rules should be no more restrictive for behavioral health than for comparable medical care.

In-network and out-of-network care

Insurance usually covers more of the cost when you use in-network providers. Some plans offer out-of-network benefits; others do not. If a program is out of network, ask about single-case agreements, in which the insurer agrees in advance to cover care at an in-network rate. Federal rules also offer some protections for certain out-of-network situations, so ask the insurer what applies.

Prior authorization and coverage decisions

Many plans require prior authorization before covering residential or inpatient treatment, and sometimes before outpatient treatment as well. The program often handles this, but it helps to understand the process. If coverage is denied, there is usually an internal appeal and then an external review. Ask the insurer for the exact reason for a denial and the deadline to appeal.

Questions to ask your plan

Is this provider or program in network?
Is prior authorization required, and how long does it take?
What is covered at each level of care, and are there visit or day limits?
What are my deductible, copay, coinsurance, and out-of-pocket maximum?
Are medications for opioid use disorder or psychiatric medications covered?
What is the process to appeal a denial?

Frequently asked questions

Does the Affordable Care Act cover mental health treatment?

Marketplace plans under the Affordable Care Act must cover mental health and substance use disorder services as one of the essential health benefits. What exactly is covered and what you pay depends on the specific plan. Confirm with your insurer.

Can my plan limit how many therapy sessions I get?

Federal parity law generally prohibits plans from applying more restrictive limits to mental-health and substance-use benefits than to comparable medical benefits. If you believe a limit is improper, you can appeal and can contact your state insurance regulator.

What if my claim is denied?

Ask for the reason in writing and the deadline to appeal. Plans must offer an internal appeal, and most offer an external review. The program's billing office or a patient navigator can often help you through it.

Does Medicare cover addiction treatment?

Medicare covers many mental-health and substance-use services, with different rules for inpatient and outpatient care and for opioid treatment programs. Because coverage changes, confirm with Medicare or the specific program what is covered in your situation.
