Mental Health Parity Laws: What Your Insurance Must Cover

Understanding Mental Health Parity Laws

When you buy health insurance, you expect it to cover your medical needs fairly. However, many people worry that mental health care is treated differently than physical health care. The good news is that federal law requires your insurance plan to provide equal coverage for both.

This requirement is known as the Mental Health Parity and Addiction Equity Act, or MHPAEA. Passed in 2008, this law ensures that financial requirements and treatment limits for mental health conditions are no more restrictive than those for physical health conditions. If your plan covers a visit to a cardiologist, it must also cover a visit to a therapist.

Why Parity Matters for Your Health

Mental health conditions like depression and anxiety are common medical issues. They require treatment just like a broken bone or high blood pressure. Without parity laws, insurance companies might charge higher fees or limit the number of therapy sessions you can attend.

Research shows that when people have access to affordable mental health care, they recover faster and stay healthier overall. Parity laws help remove barriers that prevent you from getting the help you need.

Financial Requirements You Must Know

One of the most important parts of parity is how much you pay. Your insurance plan cannot make you pay more for mental health care than for physical health care.

Copays and Coinsurance

A copay is a fixed amount you pay for a service, like $20 per visit. Coinsurance is a percentage of the cost, like 20% of the bill. Under parity laws, the copay for seeing a psychologist must be the same as the copay for seeing a primary care doctor.

If your plan has a deductible, the amount you must pay before insurance kicks in must be the same for mental health and physical health. You cannot be required to meet a higher deductible for therapy sessions than for a visit to the ER.

Here are the key financial rules you should check:

  • Copays: Must be equal for mental and physical visits.
  • Deductibles: Must be the same for both types of care.
  • Out-of-Network: Costs must be equal if covered at all.

Out-of-Network Costs

Sometimes you need a specialist who is not in your insurance network. Parity laws protect you here too. If your plan covers out-of-network care for physical health, it must cover it for mental health.

The amount you pay out-of-network cannot be higher for mental health services. For example, if your plan pays 80% of the cost for an out-of-network surgeon, it must pay 80% for an out-of-network psychiatrist.

Important: Some plans do not cover out-of-network care at all. If this is the case for physical health, it must also be the case for mental health.

Treatment Limits and Restrictions

Insurance companies sometimes try to limit how many times you can see a provider. Parity laws restrict these limits.

Visit Limits

Many plans used to limit therapy to 20 visits per year. Now, if your plan limits physical health visits, it must limit mental health visits equally.

If your plan does not limit visits for physical health, it cannot limit visits for mental health. For example, if you can see a specialist as many times as needed for a chronic condition, you should be able to do the same for mental health.

Other Treatment Limits

Plans cannot use stricter rules for mental health care. This includes prior authorization, which is when you need approval before getting treatment.

If your plan requires approval for a physical therapy session, it must require the same level of approval for mental health therapy. The rules for getting approved should be similar.

For example, if a doctor can authorize a surgery without extra steps, a therapist should be able to authorize medication without extra steps.

Substance Use Disorder Coverage

The MHPAEA also covers substance use disorder treatment. This includes treatment for alcohol and drug addiction.

Your plan must cover addiction treatment the same way it covers other medical conditions. This applies to inpatient care, outpatient care, and medication-assisted treatment.

You should not face higher costs or fewer visits for addiction treatment compared to other health issues. If your plan covers a hospital stay for a heart attack, it must cover a hospital stay for an overdose.

Network Adequacy and Access

Having insurance is not enough if you cannot find a doctor who accepts it. Parity laws require a sufficient network of providers.

Finding In-Network Providers

Your insurance company must have enough mental health providers in their network. They cannot claim there are no therapists available if they have plenty of physical health doctors.

If you cannot find an in-network provider, your plan may need to cover out-of-network care at in-network rates. This helps ensure you are not stuck paying more just because there are no local therapists.

Wait Times

How long you wait for an appointment matters. If your plan allows you to see a specialist within two weeks for physical health, they must allow the same wait time for mental health specialists.

Long wait times can delay treatment and make conditions worse. Parity laws help ensure you get timely access to care.

Access to mental health care is a basic part of health insurance. Federal laws ensure you get the support you need to live a healthy life.

What To Do If Your Claim Is Denied

Even with laws in place, insurance companies sometimes make mistakes. You have the right to appeal a denial.

The Internal Appeal Process

Start by asking your insurance company to review the decision. They must give you a reason in writing. Keep copies of all letters and emails.

Ask for a copy of your plan documents. These documents explain exactly what your coverage includes. Compare the denial reason to your plan rules.

Follow these steps to file an appeal:

  • Get the denial letter from your insurance company.
  • Write a letter explaining why the care is needed.
  • Include medical records from your doctor.
  • Send the appeal within the deadline listed on your plan.

Filing an External Review

If the insurance company still says no, you can ask for an independent review. An outside expert will look at your case.

This review is free for you. The insurance company must follow the decision made by the independent reviewer. You can find more information on your state insurance department website.

If you have an employer plan, you can also contact the Department of Labor. They oversee plans under the Employee Retirement Income Security Act, or ERISA.

Reporting Violations

If you believe your plan is breaking the law, you can report it. The Centers for Medicare and Medicaid Services handles federal complaints.

You can also contact your state insurance commissioner. They enforce state laws that might offer even more protection than federal laws.

Conclusion

Knowing your rights under mental health parity laws gives you power over your health care. You deserve coverage that treats your mind as seriously as your body.

Review your insurance plan documents carefully. Check your copays, visit limits, and network options. If you face barriers, use the appeal process to get the care you need.

Access to mental health care is a basic part of health insurance. Federal laws ensure you get the support you need to live a healthy life.
