Most group health plans are out of compliance with the Mental Health Parity and Addiction Equity Act and most employers who sponsor those plans don’t know it.
That is not a provocative claim. It is the conclusion drawn from years of Department of Labor enforcement data, and it is precisely why federal regulators issued a strengthened final rule in 2024 with explicit 2026 compliance requirements. The DOL is now actively issuing enforcement letters. Audits are underway. The plans most at risk are mid-size employer-sponsored group health plans, exactly the ones where HR is often managing compliance alone, without dedicated legal counsel reviewing plan design.
July is Minority Mental Health Awareness Month, and the timing is a useful reminder: the mental health parity rule is not an aspirational policy. It is a federal compliance obligation with real enforcement consequences, and the gap between what most employer plans promise and what they actually deliver is closing on the government’s terms.
What the Rule Actually Requires
The Mental Health Parity and Addiction Equity Act has been on the books since 2008, but meaningful enforcement was limited for most of that period. The Consolidated Appropriations Act of 2021 changed that trajectory by requiring group health plans to perform, document, and make available a Non-Quantitative Treatment Limitation comparative analysis, commonly called an NQTL analysis, demonstrating that mental health and substance use disorder benefits are not treated more restrictively than medical and surgical benefits.
In plain terms: if your plan requires prior authorization for inpatient psychiatric care, it must apply equivalent prior authorization logic to inpatient medical and surgical care. If your plan uses step therapy protocols before covering certain mental health medications, comparable requirements must govern medical treatments. Network composition standards for behavioral health providers, out-of-network reimbursement rates for mental health services, and care management criteria are all subject to parity analysis.
The 2024 final rule, with 2026 compliance deadlines for most plan provisions, goes further: plans cannot simply assert compliance, they must produce a written, documented analysis and make it available to regulators and plan participants on request. According to the Department of Labor, the vast majority of NQTL analyses reviewed in enforcement actions to date have been found deficient.

Why Mid-Size Employers Face the Greatest Exposure
Large employers with dedicated benefits teams and legal counsel have, in many cases, worked through the NQTL analysis process. Mid-size employers with 25 to 500 employees are significantly more likely to have assumed their carrier or TPA manages compliance, and in many cases, that assumption is wrong.
For self-funded and level-funded plans, the compliance obligation belongs to the plan sponsor (the employer), not the carrier. For fully insured plans, the carrier bears primary responsibility, but the employer remains liable for deficient plan design. Either way, the employer is not insulated by pointing at the carrier.
According to Spring Health’s 2026 Workplace Mental Health Report, 69% of employees say mental health benefits play a vital role in their job decisions, a figure that rises to 83% among workers ages 18 to 34. Mental health has also appeared for the first time among the top conditions driving employer healthcare costs, according to UnitedHealthcare’s 2026 employer benefits analysis. Compliance failure is not only a legal risk, it is a benefits quality issue that affects the employees a health plan is supposed to protect.
What HR Leaders Should Do Before the Next Renewal
Start with your carrier or TPA. Ask specifically whether an NQTL analysis has been completed for your plan and whether it is documented and available for review. A vague answer is itself informative. Engage your benefits broker on a formal HR compliance review to identify which plan design features are most likely to generate parity scrutiny. An employee benefits strategy review conducted now gives employers enough runway to address gaps before plan year renewal. July is the right moment: the design is still open, and the documentation burden is manageable before the compliance window tightens further.
