Mental Health Parity and Addiction Equity Act (MHPAEA) regulatory requirements are among the most complex and technical of all regulatory mandates applicable to group health plans. At a high level, MHPAEA prohibits group health plans from imposing barriers on access to mental health or substance use disorder (MH/SUD) benefits that do not apply to medical and surgical (M/S) benefits.
As group health plan fiduciaries, employers and plan sponsors must be prepared to respond to participant and regulator requests for a copy of an up-to-date Non-Quantitative Treatment Limitation (NQTL) Comparative Analysis demonstrating that their Plans are compliant with the MHPAEA.
Regulators continue to demonstrate their commitment to enforcement of these requirements, as highlighted by the following.
The stated goal of the recent final agency regulations was to enhance access to MH/SUD benefits in light of the ongoing MH/SUD crisis in the U.S. The following NQTLs were therefore identified as top enforcement priorities:
The NQTL Comparative Analysis report required by the MHPAEA is not, however, limited to these enforcement priorities. Reports must also include an analysis confirming all other NQTLs applied by a Plan satisfy MHPAEA requirements. Examples of other NQTLs include prescription drug formulary designs; network tier designs; methods for determining out-of-network (OON) rates (such as allowed methods for determining usual, customary, and reasonable charge amounts and application of external benchmarks for OON rates); fail first policies or step therapy protocols; and restrictions based on geographic location, facility type, provider specialty, or other criteria that limit the scope or duration of Plan benefits.
In the first two years following the enactment of CAA 2021, the US Department of Labor (DOL) reportedly made extraordinary efforts to give group health plans opportunities to cure deficiencies in their NQTL Comparative Analysis reports. Recently, the DOL has indicated that it expects more complete NQTL Comparative Analyses from the start of its review process and may not be as generous as in prior years before issuing a final determination of non-compliance. Moreover, several court cases have been filed alleging MH/SUD coverage limitations violate MHPAEA.
To mitigate such regulatory and litigation exposure, employers and plan sponsors will need to ensure their MHPAEA compliance, as follows.
This NQTL Comparative Analysis process is complex requiring the collection of detailed clinical data from group health plan vendors that establish and administer NQTLs, an associated analysis of that data (to demonstrate written compliance), testing of NQTL data (to demonstrate operational outcomes compliance) and the preparation of a report that comports with onerous content requirements. Moreover, employers and plan sponsors who sponsor ERISA covered plans (i.e., most group health plans other than those sponsored by churches or governmental entities) are now required to certify that they have engaged in a prudent process to select and monitor at least one qualified service provider to complete the required NQTL Comparative Analysis.
The final regulations set forth important timeframes regarding the NQTL Comparative Analysis, including:
The final rules generally apply to group health plans and group health insurance coverage on the first day of the first plan year beginning on or after January 1, 2025.
Employers and plan sponsors must take steps now to ensure compliance and prepare to respond quickly to requests from federal regulators or plan participants regarding NQTL Comparative Analysis.
