Few employers that outsource the administration of mental health benefits to separate companies from their medical benefits are adequately verifying whether these mental health offerings truly align with the standards of medical benefits, according to recent findings by officials at the federal Employee Benefits Security Administration (EBSA). This oversight is creating significant compliance gaps under the Mental Health Parity and Addiction Equity Act (MHPAEA), potentially denying employees equitable access to crucial behavioral health care.
In a new report submitted to Congress detailing MHPAEA enforcement efforts, EBSA officials highlighted a critical deficiency: "Plans with these carveout arrangements rarely obtained a complete comparative analysis from either service provider, especially where the service providers were not communicating with each other or aware of the processes, strategies, evidentiary standards or other factors used by the other." This lack of integrated oversight and communication between distinct benefit administrators is a primary impediment to achieving true parity, leaving employers vulnerable to compliance violations and employees facing potential barriers to necessary treatment. EBSA’s stern recommendation to employers is to "closely review the information provided by their service providers to ensure there is a meaningful comparison of information provided by each service provider."
The report underscores a persistent challenge in the landscape of employer-sponsored health plans: the complex and often misunderstood requirements of mental health parity laws. This issue affects millions of Americans who rely on employer-sponsored health plans for their medical and behavioral health needs. With an estimated 19% of U.S. adults experiencing a mental illness in the past year, and 13.5% of adults reporting a substance use disorder, according to the Substance Abuse and Mental Health Services Administration (SAMHSA), the equitable provision of these benefits is not merely a regulatory mandate but a critical public health imperative.
The Genesis of Mental Health Parity: MHPAEA’s Mandate
The Mental Health Parity and Addiction Equity Act (MHPAEA) of 2008 was enacted to address a long history of discriminatory practices in health insurance plans, where mental health and substance use disorder (MH/SUD) benefits were often subject to more restrictive limitations than medical and surgical benefits. Prior to MHPAEA, it was common for plans to impose higher co-payments, stricter visit limits, or separate deductibles for mental health care, effectively creating a two-tiered system of care. MHPAEA built upon the foundational Mental Health Parity Act of 1996, which primarily focused on lifetime and annual dollar limits.
MHPAEA expanded these protections significantly, requiring that financial requirements (like deductibles, copayments, out-of-pocket maximums) and treatment limitations (like frequency of treatment, duration of treatment, facility type) applicable to MH/SUD benefits be no more restrictive than the predominant financial requirements and treatment limitations applied to substantially all medical and surgical benefits. Furthermore, the Affordable Care Act (ACA) of 2010 strengthened MHPAEA by classifying MH/SUD services as essential health benefits, thereby expanding its reach to individual and small group markets and ensuring a broader scope of covered services.
EBSA, a U.S. Department of Labor agency, is charged with protecting the integrity of employee benefit plans under the Employee Retirement Income Income Security Act (ERISA), including ensuring compliance with MHPAEA. Alongside the Centers for Medicare & Medicaid Services (CMS) within the U.S. Department of Health and Human Services (HHS), EBSA annually reports to Congress on its enforcement efforts and the state of MHPAEA compliance across the nation. These reports serve as crucial benchmarks for assessing progress and identifying persistent challenges in achieving true parity.
The Intricacies of "Carve-Out" Arrangements
The core of the compliance challenge identified in EBSA’s latest report lies in "carve-out" arrangements. This term refers to a common practice where employers, particularly large self-insured entities, contract with one vendor (often a traditional health insurer) to administer medical and surgical benefits, while a separate vendor (often a specialized behavioral health organization or third-party administrator) manages mental health and substance use disorder benefits. While intended to leverage specialized expertise, this separation frequently leads to a fragmentation of oversight and a lack of holistic comparison.
The inherent problem with carve-out models, as highlighted by EBSA, is the absence of a unified perspective. The medical benefits administrator may have robust processes for determining medical necessity, network adequacy, or prior authorization criteria for physical ailments, but these processes are often entirely opaque to the mental health benefits administrator, and vice versa. This operational silo means that the "comparative analysis" – the rigorous evaluation required by MHPAEA to demonstrate that MH/SUD benefits are truly on par with medical benefits – is either not conducted comprehensively or relies on incomplete data from disconnected sources.
For instance, if a medical plan requires prior authorization for an elective surgery only after an outpatient consultation, but the mental health plan requires prior authorization for all forms of outpatient therapy from the first session, this could constitute a parity violation. Without a meticulous, side-by-side comparison, employers may inadvertently perpetuate discriminatory practices. EBSA officials specifically note that when asked for these analyses, many submitted by plans and plan administrators were found to be "weak," lacking the depth and detail required to satisfy parity standards.
EBSA’s Enforcement Footprint: A Closer Look at Violations
The recent report details EBSA’s enforcement activities from August 1, 2023, through July 31, 2025 – a period reflecting ongoing regulatory scrutiny. During this timeframe, EBSA issued 42 letters to plans, formally requesting "comparative analyses" of their behavioral health and medical benefits. These letters are often the first step in an enforcement action, signaling that EBSA has identified potential parity violations requiring detailed justification from the plan.
The violations prompting these requests were diverse but indicative of common problem areas:
- Provider Network Adequacy (14 cases): A significant number of letters related to the rules governing what kinds of providers can participate in a plan’s network. This often involves discrepancies where medical networks are broad and accessible, but mental health networks are overly restricted, leading to long wait times or limited choices for patients.
- Exclusions for Speech or Occupational Therapy (8 cases): Concerns were raised regarding plans that impose blanket exclusions or overly restrictive limits on therapies like speech or occupational therapy, which are often crucial for individuals with developmental or neurological conditions, when similar services for physical conditions are covered more generously.
- Limitations on Autism Therapy (8 cases, excluding Applied Behavioral Analysis): Eight letters focused on limitations placed on various forms of therapy for people with autism, distinct from the specific exclusion of Applied Behavioral Analysis (ABA). This indicates scrutiny of overall access to comprehensive autism care.
- Exclusions for Nutritional Counseling (7 cases): EBSA investigated plans that excluded or severely limited nutritional counseling, particularly when such services are covered for physical health conditions like diabetes or heart disease.
- Exclusions for Applied Behavioral Analysis (ABA) Therapy (6 cases): Despite its proven efficacy for autism spectrum disorder, some plans continue to exclude or severely limit ABA therapy, a practice that directly contradicts parity principles if similar evidence-based treatments for medical conditions are covered.
These specific areas of enforcement highlight EBSA’s focus on non-quantitative treatment limitations (NQTLs), which are often more subtle and challenging to identify than quantitative limits (like visit caps). NQTLs include medical necessity criteria, prior authorization requirements, step therapy protocols, and network admission standards, all of which must be applied equitably between MH/SUD and medical/surgical benefits.
A stark illustration of compliance failure cited in the report involved a plan administrator that updated its claim-processing systems for self-insured employer plans’ medical benefits but neglected to do the same for the employer plans’ mental health benefits. This technological disparity led directly to parity problems, demonstrating how operational neglect can result in systemic discrimination against mental health care.
Employer Accountability and the Education Gap
A recurring theme in EBSA’s reports is the persistent need for greater employer education regarding MHPAEA compliance. Officials note that some employers with self-insured health plans "were surprised to find that responsibility for MHPAEA compliance lies with the plan, not their service provider." This misconception is a critical barrier to compliance. While third-party administrators (TPAs) and insurers play a vital role in benefit administration, the ultimate legal responsibility for MHPAEA compliance rests with the plan sponsor – typically the employer. This means employers cannot simply delegate responsibility and assume their vendors are fully compliant; they must actively oversee and audit their benefit arrangements.
This lack of understanding is particularly concerning given the significant financial implications of non-compliance. EBSA enforcement efforts generally can yield substantial recoveries; for example, a separate report indicated EBSA enforcement efforts yielded $1.4 billion in recoveries across various benefit areas, signaling the agency’s capacity for impactful enforcement. While not all directly tied to MHPAEA, it underscores the financial risks associated with benefit plan non-compliance. Benefits consultants and legal experts routinely advise employers to conduct thorough due diligence on their benefit providers and regularly audit their plans for parity compliance to mitigate these risks.
A Shifting Regulatory and Enforcement Landscape
The report also provides a glimpse into the evolving philosophy of the Department of Labor (DOL) under different administrations regarding benefits law compliance. The report notes that officials in the administration of President Donald Trump had previously promised to shift focus towards educating employers about benefits law compliance, potentially moving away from a primary emphasis on litigation and prosecution. This shift aligns with a broader administrative goal of fostering voluntary compliance through guidance and outreach.
However, this new approach to compliance does not imply a relaxed stance on mental health parity. The DOL’s commitment to education coexists with a clear expectation of adherence to federal law. The report itself, covering enforcement actions extending into mid-2025, suggests that EBSA continues to actively monitor and enforce MHPAEA, regardless of broader policy statements.
Adding another layer of complexity, the Trump administration DOL officials have reportedly rescinded parity regulations approved during the Biden administration and are currently engaged in drafting replacement regulations. This regulatory flux creates uncertainty for employers and plan administrators, who must navigate changing guidelines while maintaining continuous compliance.
Daniel Aronowitz, the Assistant Labor Secretary who serves as Administrator of EBSA, has voiced concerns that the current benefits comparison requirements have "worked poorly." He has indicated a preference for focusing more on patients’ ability to access care and less on the intricate details of benefits comparisons. This perspective suggests a potential future direction where enforcement might prioritize patient outcomes and real-world access over purely technical comparative analyses, though the immediate practical implications of such a shift are yet to be fully realized. Despite Aronowitz’s stated preference, the current report, whose review period for enforcement actions ended in mid-2025, strongly indicates that EBSA, at least for now, still expects employers and their plan administrators to demonstrate a concerted effort in checking whether their behavioral health benefits are genuinely comparable to medical benefits.
Broader Implications and the Path Forward
The findings of EBSA’s report carry significant implications for various stakeholders:
- For Employees and Patients: The failure to ensure parity in carve-out arrangements directly impacts access to mental health and substance use disorder care. Inadequate networks, restrictive treatment limitations, or confusing administrative hurdles can lead to delayed treatment, increased out-of-pocket costs, and ultimately, poorer health outcomes. True parity is essential for destigmatizing mental health conditions and integrating behavioral health into overall healthcare.
- For Employers: Beyond regulatory penalties, non-compliance can lead to employee dissatisfaction, reduced productivity due to untreated conditions, and potential lawsuits. Employers bear a fiduciary responsibility under ERISA, and demonstrating due diligence in MHPAEA compliance is paramount. This necessitates not just contracting with a vendor, but actively monitoring their performance and ensuring their practices align with parity standards.
- For the Healthcare System: The fragmentation highlighted by carve-out arrangements reflects a broader challenge in integrating physical and behavioral healthcare. Achieving true parity requires greater collaboration and data sharing between different parts of the healthcare ecosystem.
- For Regulators: EBSA and CMS face the ongoing challenge of providing clear, actionable guidance to employers while robustly enforcing complex regulations. The tension between emphasizing education and maintaining enforcement pressure is delicate, especially amidst shifting administrative priorities and evolving regulatory frameworks.
As mental health and substance use disorder crises continue to affect communities nationwide, the importance of MHPAEA compliance cannot be overstated. The EBSA report serves as a critical reminder that while the law exists, its effective implementation requires vigilant oversight, proactive employer engagement, and a concerted effort from all parties involved in the administration of employee benefits. The path forward demands a deeper understanding of parity requirements, improved communication between benefit providers, and a steadfast commitment from employers to ensure that mental health is treated with the same importance as physical health.
