In our last post, we considered some of the comment letters submitted in response to proposed regulations under the Mental Health Parity and Addiction Equity Act (MHPAEA) issued by the US Departments of Labor, Health and Human Services and the Treasury (the Departments). Our previous MHPAEA content is available here.

The comment period for the proposed regulations closed on October 17, 2023. Stakeholders submitted more than 7,500 comments. While we have not read them all, we’ve seen enough to discern the broad contours. There are those in favor, those opposed and those that take some middle ground with recommended modifications. Among the latter, the modifications run the gamut from trivial to substantive. One particular comment generally approving of the rule but urging modifications caught our attention. It was submitted by the Brookings Institution, and it offered the following (at least in our view) useful insights.

Heterogeneity of Mental Health/Substance Use Disorder (MH/SUD) Benefits Versus Medical/Surgical (M/S) Benefits

The comment explains that roughly 41% of M/S visits are for chronic conditions, which are less likely to be subject to concurrent review. In contrast, between 64% and 69% of MH/SUD visits focus on treatment of mood disorders, anxiety disorders, psychoses and personality disorders, i.e., chronic recurring conditions. The comment notes: “Even if all chronic visits in general medical practice were subject to concurrent review, any concurrent review for mental health or substance use disorder services would fail the ‘substantially all’ test.” (Emphasis added)

The comment recommends that the Departments consider a more fine-grained method of comparing the use of nonquantitative treatment limitations (NQTLs) between MH/SUD benefits and those for M/S benefits.

Schematic Representation of NQTLs (and Why This Matters)

The comment expresses concern over the depth of the analysis that is required for each NQTL. Page four provides a useful schematic that fleshes out the particulars. The schematic makes the point that a substantial amount of effort is involved in demonstrating compliance for a single NQTL. The steps include “identifying which services apply [ ], identifying factors considered in the design of the NQTL, identifying sources used to define these factors, and demonstrating that the NQTL is applied no more stringently to mental health and substance use disorder benefits than medical/surgical benefits.”

Moreover, all steps must be repeated for each additional NQTL. While even a casual review of the proposal would lead the reader with the sense that compliance would be a challenge, the use of the visual schematic drives the point home visually.

The Exception for Independent Professional Medical or Clinical Standards

The proposed rule identifies two exceptions to the NQTL requirements, the first of which is based on “Independent Professional Medical or Clinical Standards.” While there is a good deal of disagreement as to its proper scope and even its utility, the Brookings comment worries that “the language in the proposed rule also opens the door to regulatory gaming because it is overly broad.” According to the comment: “If the [...]
