Comments submitted in response to the proposed regulations under the Mental Health Parity and Addiction Equity Act (MHPAEA) reflect a broad range of perspectives. Our previous MHPAEA content is available here.
A nontrivial subset of the comments single out a particular nonqualified treatment limitation (NQTL) for special treatment or scrutiny. An example of this trend is found in an October 16, 2023, comment letter submitted by the Legal Action Center. The letter asks the US Departments of Labor, Health and Human Services, and the Treasury (the Departments) to address the rule’s treatment of medical standards of care and medical necessity.
Under the 2013 final MHPAEA regulations, a plan or issuer may not impose an NQTL with respect to mental health/substance use disorder (MH/SUD) benefits in any classification unless the processes, strategies, evidentiary standards or other factors used in applying the NQTL in the classification are comparable to, and are applied no more stringently than, the processes, strategies, evidentiary standards or other factors used in applying the limitation with respect to medical/surgical (M/S) benefits. (Classifications for this purpose include inpatient, in-network; inpatient, out-of-network; outpatient, in-network; outpatient, out-of-network; emergency care; and prescription drugs.)
The proposed regulation defines “strategies” as “practices, methods, or internal metrics that a plan or issuer considers, reviews, or uses to design an NQTL.” Compliance with and deviations from generally accepted standards of care are cited as examples. Strategies for this purpose include “the development of the clinical rationale used in approving or denying benefits,” which is the central purpose of medical necessity determinations.
Medical necessity criteria are considered NQTLs because the criteria have the capacity to limit a patient’s access to or duration of MH/SUD treatment that are not based on the frequency of treatment, number of visits, days of coverage or days in a waiting period (the latter are quantitative treatment limitations). The Legal Action Center claims that plans sometimes develop their own criteria for determining medical necessity for MH/SUD treatment or use criteria developed by nonprofit clinical specialty associations or industry entities, despite the law’s admonition that plans must treat the two comparably. Concerned that under the proposed regulation plans retain significant discretion to adopt overly restrictive medical necessity criteria, the Legal Action Center asks the Departments to revise the definition of “strategies” to include a definition of “generally accepted standards of care” that is tied to criteria and guidelines from the nonprofit clinical association for the relevant specialty.
One way to determine the quality of a medical necessity definition is to look at claims data, which offer a useful test of parity compliance. Current law does not require parity of outcomes, but the proposed regulation does. The proposed rule would require that plans collect and evaluate outcomes data for the express purpose of assessing the impact of the NQTL on access to MH/SUD benefits. Material differences in outcomes are viewed as a strong indicator of noncompliance. (For the network composition NQTL, a material difference in outcomes data [...]
