- You can appeal unfair denials and file complaints if your mental health coverage is treated differently.
Trying to get mental health care can already feel like a lot. Finding out your insurance covers fewer therapy visits than medical appointments or charges higher costs for psychiatric care can make it even harder. The mental health parity law was created to help prevent these situations.
The Mental Health Parity and Addiction Equity Act (MHPAEA) requires several health insurance plans to treat mental health and substance use disorder benefits comparably to medical and surgical benefits. Understanding your rights can help you feel more confident when reviewing your insurance coverage, appealing a denial, or looking for care. Here’s what the law covers, how it works, and what you can do if your benefits seem unfair.
Understanding the Mental Health Parity and Addiction Equity Act
The Mental Health Parity and Addiction Equity Act (MHPAEA), passed in 2008, is a U.S. federal law that prevents health plans from imposing more restrictive limitations on mental health and substance use disorder benefits than on medical and surgical benefits. These parity protections apply to costs, treatment limits, and administrative requirements.
That means an insurance plan usually cannot:
- Charge higher copays for therapy visits than for comparable medical visits
- Limit therapy sessions more strictly than physical health visits
- Require tougher approval rules for psychiatric care
- Create tougher access barriers for mental health treatment
The law applies to many types of insurance plans, though some plans are exempt. Federal parity protections also work alongside state mental health coverage laws, which may provide additional protections depending on where you live.
Which health plans must follow parity requirements?
Many employer-sponsored and Marketplace health plans must follow parity rules.
According to the U.S. Department of Labor (DOL), parity protections generally apply to:
- Employer-sponsored group health plans
- Individual and small-group Marketplace plans
- Medicaid managed care plans
- Children’s Health Insurance Program (CHIP) plans
Some plans may be exempt from federal parity requirements, including:
- Retiree-only plans
- Certain small employer plans
- Some church-sponsored plans
- Certain short-term limited-duration plans
Exemptions exist because different insurance plans are regulated under different laws and systems.
Why the Mental Health Parity Law Matters for Your Coverage
The mental health parity law helps reduce unfair barriers that can make mental health care harder to access than physical health care. Before parity protections existed, many insurance plans charged higher costs for therapy, limited counseling visits, or denied behavioral health treatment more often than medical care.
Unequal insurance coverage contributed to delays in treatment and lower access to care. Today, the law helps address many of those barriers by requiring comparable treatment between behavioral health and medical care. Some common examples of possible parity concerns include:
These barriers matter because cost and insurance challenges can affect whether someone continues care. According to the National Alliance on Mental Illness (NAMI), cost remains one of the biggest reasons people delay or avoid treatment.
"Due to the parity laws, the ability to seek mental health professionals has become a bit easier. However, if changes to health plans or change in employment happen, clients often struggle with the choice to stay on with their established therapist or seek someone in network. This scenario is a key example of clients hesitating on continued treatment. Both options are daunting as one has a financial cost added to it and the other has a mental cost of having to find a new therapist and rebuilding a rapport with them."

What Mental Health and Substance Use Services Must Be Covered
The parity law does not require every plan to cover every mental health service, but it does require equal treatment when coverage exists. If a plan includes mental health or substance use disorder benefits, those benefits generally must be treated comparably to physical medical benefits.
Many plans commonly cover:
- Outpatient therapy
- Psychiatric care
- Medication management
- Inpatient mental health treatment
- Substance use disorder treatment
- Mental health crisis intervention services
The exact services covered depend on your insurance plan. Importantly, plans generally cannot impose stricter visit limits, copays, deductibles, coinsurance requirements, or approval processes for mental health services than they do for comparable medical care.
Comparing mental health benefits to medical benefits
The Department of Labor's parity guidance uses six benefit classifications as the comparison framework:
Online therapy covered by insurance
Therapy with licensed Talkspace providers is covered by many insurance plans for only a copay.
Check coverage- Inpatient, in-network
- Inpatient, out-of-network
- Outpatient, in-network
- Outpatient, out-of-network
- Emergency care
- Prescription drugs
When evaluating your own coverage, compare mental health benefits to medical benefits within the same classification. Look at deductibles, copayments, coinsurance, out-of-pocket maximums, and visit limits. Also, pay attention to nonquantitative factors like prior authorization requirements, network size, and formulary design, all of which must be applied comparably.
How Insurance Plans Must Apply Parity Standards
Parity standards fall into two broad types: quantitative and nonquantitative. Both must be applied equally across mental health and medical benefits.
Quantitative treatment limitations (QTLs) are the measurable ones: visit caps, day limits, and frequency restrictions. Your plan cannot impose a stricter visit limit on outpatient therapy than it does on outpatient physical health visits within the same classification. The same logic applies to financial requirements: copays, deductibles, coinsurance, and out-of-pocket maximums must all be no more restrictive for behavioral health care than for medical care.
Non-quantitative treatment limitations and equal application
Non-quantitative treatment limitations are rules or processes that affect access to care without using specific numbers. According to the Department of Labor's Self-Compliance Tool for the MHPAEA, NQTLs include the methods health plans use to decide whether treatment is covered.
Examples include:
- Prior authorization requirements
- Medical necessity reviews
- Provider reimbursement rates
- Step therapy requirements
- Network admission standards
- Prescription drug formulary design
These rules must generally be applied comparably to both mental health and medical benefits. For example, a health plan may raise parity concerns if it requires extensive approval steps for therapy while approving similar medical services more easily.
Does Insurance Have to Cover Mental Health Services?
Insurance does not always have to cover mental health care, but when mental health benefits are offered, parity protections usually apply. The mental health parity law focuses on equal treatment, not mandatory coverage. That means the law generally does not force every health plan to include behavioral health benefits.
However, some plans are required to include mental health coverage under other laws. For example, Affordable Care Act Marketplace plans must include mental health and substance use disorder services as essential health benefits, per the Department of Health & Human Services.
"A person's mental health stability is just as important as their physical health stability. The two are often tied together and work in tandem to help or hurt each other. Making sure access to consistent and ongoing mental health treatment will have benefits in their physical health through managing stressors that can contribute to other health related issues. Just as seeing a primary care for follow ups and check ups consistently, meeting with a mental health professional also allow for that consistent upkeep of health overall."
- Talkspace Therapist, Minkyung Chung, MS, LMHC
Why is the mental health parity law important here? Because even when plans offer mental health benefits, the law helps prevent insurers from making those benefits harder to use than medical coverage.
Recognizing Potential Parity Violations
A health plan may violate parity rules if it applies stricter requirements to get mental health care than to comparable medical care. Some warning signs are easier to spot than others. According to the Department of Labor, potential parity concerns may include:
- Higher out-of-pocket costs for therapy visits
- Stricter prior authorization for mental health care
- Smaller behavioral health provider networks
- More frequent denials for psychiatric services
- Tougher medical necessity standards for therapy or substance use treatment
Not every denial automatically means your rights were violated. Sometimes claims are denied for reasons unrelated to parity. The key question is whether your plan treats mental health care more restrictively than similar medical care.
Steps to Take When Your Coverage Rights are Violated
If you believe your plan treated your mental health benefits unfairly, keeping detailed records can help support your case.
Start by reviewing:
- Your Summary of Benefits and Coverage
- Explanation of Benefits (EOB) documents
- Denial letters
- Prior authorization notices
Keep copies of emails, letters, and notes from phone calls with your insurance company.
You can also ask your insurer for a detailed explanation of how parity standards were applied to your claim.
Filing an appeal with your insurance company
You have the right to appeal many insurance denials through your health plan’s internal review process. Most health plans are required to provide a way for members to challenge denied claims or coverage decisions.
When filing an appeal:
- Submit your appeal before the plan’s deadline
- Include letters or records from your provider if possible
- Explain why you believe the denial may violate parity protections
- Ask the insurer to explain how the decision was made
Your insurance company must review the appeal and provide a written response explaining its decision. If your appeal is denied, you may also qualify for an independent external review.
Filing a complaint with regulators
You can contact government agencies if internal appeals do not resolve the issue. Depending on your plan type, you may contact:
- The Department of Labor for many employer-sponsored plans
- Your state insurance department for state-regulated plans
- The Centers for Medicare & Medicaid Services (CMS) for Marketplace plans
Regulators may review whether your plan applied stricter standards to mental health benefits than to medical benefits.
Recent Updates and Regulatory Changes to Parity Protections
The mental health parity law has become stronger over time, especially when it comes to how insurance companies manage approvals and access to improve mental health care.
In 2024, the U.S. Departments of Labor, Health and Human Services, and Treasury updated the rules to increase oversight of NQTLs, or, in other words, the behind-the-scenes rules insurance companies use to make coverage decisions, such as prior authorization requirements, medical necessity reviews, and provider network standards.
Most of the updated rules began applying to many employer-sponsored health plans in 2025, with additional protections rolling out in 2026. According to the Department of Labor, the newer rules are designed to help ensure that mental health benefits are offered in a meaningful and fair way, without stricter standards than medical care.
One major change involves transparency. Insurance plans are now required to document how they apply rules like prior authorization, reimbursement rates, and network access to mental health benefits compared to medical benefits. Regulators and, in some cases, members can request this information for review. These updates are meant to make it easier to identify unfair insurance practices and improve accountability around mental health coverage.

The mental health parity law is designed to protect your access to mental health care. If your insurance plan applies stricter rules to therapy, psychiatric care, or substance use treatment than it does to medical care, you have the right to ask questions, request explanations, and appeal decisions.
