E.W. v. Health Net Life Insurance Company Archives

In a series of recent posts, we have examined a sampling of comments submitted in response to proposed regulations under the Mental Health Parity and Addiction Equity Act (MHPAEA). The proposed regulations were issued earlier this year by the US Departments of Labor, Health and Human Services and the Treasury (the Departments). Our previous MHPAEA content is available here.

This post considers a MHPAEA-related case decided by the US Court of Appeals for the Tenth Circuit, E.W. v. Health Net Life Insurance Company (available here). The case is notable because it represents the first US court of appeals to establish the elements required to state a claim under the current 2013 MHPAEA final regulations; it also provides us with an opportunity to consider how things might differ if the proposed regulation is adopted as a final rule.

Health Net involved a claim against Health Net Insurance Company and Health Net of Arizona, Inc. (collectively, Health Net) by the parents of a minor (I.W.). I.W. was admitted to a subacute care facility (an adolescent mental health residential treatment center), but her stay was cut short because it was determined that her treatment was no longer medically necessary. The determination of medical necessity was based on the application of the McKesson InterQual Behavioral Health 2016.3 Child and Adolescent Psychiatry Criteria (the InterQual Criteria).

At trial, the plaintiffs claimed that Health Net violated the MHPAEA by imposing medical necessity criteria for mental health benefits that were more stringent than those for medical/surgical benefits. The district court did not agree. On appeal, the Tenth Circuit reversed the MHPAEA claim based on the 2013 MHPAEA final regulations. (There was also an Employee Retirement Income Security Act-related claim, the dismissal of which by the district court was affirmed by the Tenth Circuit.) The Tenth Circuit held the medical necessity criteria applied by the plan to medical/surgical benefits in a subacute setting was less stringent than analogous, intermediate-level metal health benefits. In its holding, the court fashioned the following test under which, to state a claim under the MHPAEA, a plaintiff must:

Plausibly allege that the relevant group health plan is subject to the MHPAEA;
Identify a specific treatment limitation on mental health or substance use disorder benefits covered by the plan;
Identify medical or surgical care covered by the plan that is analogous to the mental health or substance use disorder care for which the plaintiffs seek benefits; and
Plausibly allege a disparity between the treatment limitation on mental health or substance use disorder benefits as compared to the limitations that defendants would apply to the medical or surgical analog.

Item (1) was not in dispute; the relevant group health plan was clearly subject to the MHPAEA. The court instead focused on, and dealt exhaustively with, each of the other three items:
