Executive Summary: Mental Health Parity in Self-Funded Plans: The Enforcement Wave and What It Requires

LFP-03.05 — The Regulatory Landscape

#

MHPAEA is the compliance domain where enforcement is most active and where self-funded plan sponsors above 50 employees are most exposed. The statute exempts self-insured plans sponsored by employers with 50 or fewer employees, which covers most of the core level funded market. But for plans above that threshold, MHPAEA compliance is mandatory and the current state of most covered plans is non-compliant.

MHPAEA imposes parity across three categories. Financial requirement parity requires that deductibles, copays, and coinsurance for mental health and substance use disorder benefits be no more restrictive than the predominant financial requirements applied to medical and surgical benefits within the same classification. Quantitative treatment limitation parity prohibits more restrictive annual or lifetime visit and day limits on mental health benefits relative to medical. Non-quantitative treatment limitation parity is the most complex and most litigated category: prior authorization requirements, step therapy protocols, network composition and reimbursement rates, formulary design, concurrent review standards, and utilization management criteria applied to mental health must be comparable to and no more stringently applied than those for medical and surgical benefits.

The CAA amendments added a specific documentation requirement. Plans must perform and document comparative analyses of NQTLs, identifying each NQTL, documenting the factors and evidentiary standards used to design it, comparing those to factors applied to comparable medical NQTLs, and evaluating parity both as written and in operation. Operational parity requires data: approval rates, denial rates, and turnaround times by benefit classification. A plan that approves 95% of prior authorization requests for medical services but 70% for mental health services has an operational disparity even if the written criteria appear comparable. Plans must document corrective actions for any identified disparities; completing the analysis without corrective action does not constitute compliance.

DOL enforcement has intensified since the CAA amendments. Common enforcement findings include plans that have not performed any NQTL analysis, plans whose analyses cover written terms but not operational parity, plans with analyses too conclusory to satisfy the requirement, and plans that identified disparities but took no corrective action. A compliant analysis for a plan above 50 employees runs from approximately $10,000 to $50,000 or more depending on plan complexity.

Plans below 50 employees are exempt from MHPAEA’s technical requirements, but employers approaching that threshold should understand the framework before they cross it. An employer that adds employees past 50 must comply with MHPAEA from the first day of the following plan year, including the NQTL comparative analysis, which requires operational data the employer may not have been tracking.
