A Brief Reintroduction to MHPAEA Comparative Analyses
The Mental Health Parity and Addiction Equity Act (MHPAEA) generally requires group health plans that offer both medical/surgical (M/S) and mental health/substance use disorder (MH/SUD) benefits to provide those benefits equally, or in parity. Although MHPAEA has existed for many years, compliance obligations received renewed attention following the Consolidated Appropriations Act, 2021 (CAA). The CAA amended MHPAEA to require that plans must produce and maintain a documented comparative analysis of nonquantitative treatment limitations (NQTLs). In other words, under this new requirement, plan sponsors had to begin proving (and maintaining proof) that their plan’s NQTLs comply with MHPAEA. Plan sponsors are also encouraged to confirm that any quantitative treatment limitations (QTLs) comply with mental health parity requirements..
In September 2024, the Department of Health and Human Services, the Department of Labor, and the Department of the Treasury (collectively, the Departments) issued a final rule that amended the existing MHPAEA regulations and added additional requirements related to NQTL compliance and comparative analyses. Following legal challenges to portions of the rule, the Departments announced a temporary non-enforcement policy with respect to certain aspects of the 2024 Final Rule. Importantly, however, the CAA’s requirement to develop and maintain NQTL comparative analyses remains in effect.
The Components of a Comparative Analysis
With that, we should examine what it takes to put together a compliant MHPAEA comparative analysis. This is typically a structured, multi-step endeavor that’s not intended for the faint of heart:
Step 1: Identify each NQTL
List all NQTLs, such as:
- Prior authorization
- Step therapy
- Network design
- Exclusions
Describe how each applies to both MH/SUD and M/S benefits
Step 2: Define scope and classifications
- Map the NQTL across benefit classifications (inpatient / outpatient / in-network / out-of-network / emergency / rx)
Step 3: Identify factors used to apply the NQTL, such as:
- Cost thresholds
- Clinical guidelines
- Utilization patterns
Documenting these factors is a critical component of an effective NQTL comparative analysis.
Step 4: Document evidentiary standards
Explain data and sources used, including:
- Internal claims data
- Vendor policies
- Clinical criteria
Clear documentation helps demonstrate MHPAEA compliance during regulatory reviews.
Step 5: Analyze comparability & stringency
A determination must be made as to whether:
- The same factors are used for MH/SUD vs M/S
- They are applied no more stringently to MH/SUD
This analysis forms the foundation of mental health parity compliance.
Step 6: Operational testing + outcomes
Evaluate how the NQTL works in practice, including:
- Claims approval and denial rates
- Assess outcomes
Step 7: Findings and conclusions
Document the following:
- Whether parity is achieved
- Any deficiencies
- Any remediation steps that will be taken
Step 8: Documentation & fiduciary oversight
- Maintain audit-ready documentation
Common Pain Points
If this process appears to be complex and overwhelming, that’s because, quite honestly, it is. This is why we really encourage plan sponsors to work with a specialist on preparing a compliant MHPAEA comparative analysis.
Many plan sponsors struggle with the comparative analysis requirement because it requires information that is often spread across multiple vendors, systems, and decision-makers. In enforcement actions and audit findings, regulators have consistently identified deficiencies in comparative analyses, particularly where plans cannot adequately document how NQTLs are designed and administered.
The most common MHPAEA compliance challenges associated with preparing and maintaining an MHPAEA comparative analysis and NQTL comparative analysis include:
- Data access and vendor dependency. Critical information is often maintained by TPAs, insurance carriers, PBMs, utilization management vendors, or network administrators. Gathering complete documentation can be time-consuming and may require coordination across multiple parties.
- Identifying all applicable NQTLs. Plan sponsors frequently underestimate the number of NQTLs that affect plan operations. Prior authorization requirements, reimbursement methodologies, provider credentialing standards, network admission criteria, and medical necessity determinations may all require review.
- Explaining factors and evidentiary standards. Regulators expect plans to identify the factors used in applying an NQTL and the evidence relied upon when developing those factors. Many analyses fall short because the underlying rationale is not sufficiently documented.
- Demonstrating operational compliance. It is not enough to describe the plan design. Plans must also evaluate how NQTLs operate in practice and whether MH/SUD benefits are treated comparably to M/S benefits.
- Ongoing maintenance obligations. Comparative analyses are not one-time projects. They should be reviewed and updated when plan designs, vendors, policies, or utilization management practices change.
- Fiduciary responsibility. Although plan sponsors often rely on consultants, TPAs, carriers, and other vendors for support, the plan sponsor ultimately remains responsible for maintaining a compliant comparative analysis and producing it when requested by regulators.
Taken together, these challenges help explain why many plans seek assistance from experienced compliance professionals when preparing and maintaining MHPAEA comparative analyses.
At Lumelight, we understand the practical challenges plan sponsors face when preparing MHPAEA comparative analyses. One of the most significant obstacles is obtaining the data and documentation necessary to support the analysis. Information is frequently maintained by TPAs, insurance carriers, PBMs, and other service providers, and gathering complete documentation can require substantial coordination.
Our team works with plan sponsors and their vendors to collect the necessary information, document the required methodologies, and prepare comprehensive comparative analyses designed to satisfy current regulatory requirements. We also review findings with plan sponsors and help identify areas that may warrant further attention or remediation.
