Mental Health Parity: What a New Court Ruling Means for Those Seeking Behavioral Health Treatment

Key Takeaways

• Courts are increasingly enforcing mental health parity protections. A recent federal court decision allowed a lawsuit to proceed where a health plan allegedly imposed stricter coverage requirements on residential behavioral health treatment than on comparable medical care.
• Coverage limitations affecting behavioral health treatment may trigger parity challenges. Requirements such as 24-hour onsite nursing mandates or blanket exclusions for certain treatment programs may violate the Mental Health Parity and Addiction Equity Act (“MHPAEA”) if similar restrictions are not applied to medical or surgical care.
• Providers and patients may have stronger grounds to challenge denied behavioral health coverage. The ruling reinforces that federal parity laws, including MHPAEA, are intended to ensure individuals seeking mental health or substance use treatment receive insurance coverage on terms comparable to medical and surgical care.

In Allison B. v. BlueCross BlueShield of Illinois, a court in the Northern District of Illinois refused to dismiss a lawsuit challenging coverage denials for a minor’s behavioral health treatment, reinforcing that insurers must apply the same standards to mental healthcare as they do to medical and surgical care.

The Facts

A parent, Allison B., sought coverage for her minor child M.B., who received treatment at two Utah facilities, Open Sky Wilderness Therapy and Maple Lake Academy. Both facilities were licensed and provided residential care for adolescents struggling with mental health issues, behavioral challenges, and substance abuse. Despite the clinical necessity, BlueCross BlueShield of Illinois denied payment for both programs. For Open Sky, the insurer cited a “wilderness program” exclusion. For Maple Lake, the insurer claimed the facility lacked 24-hour onsite nursing — a requirement the plan imposed specifically for mental health residential treatment centers.

After exhausting multiple levels of appeals and being repeatedly denied, the family filed a lawsuit alleging violations of ERISA and the Mental Health Parity and Addiction Equity Act (“MHPAEA”).

Why the Court’s Decision Matters

The court found that the family raised valid claims that the insurer applied stricter rules to mental health treatment than to comparable medical care. The plan required 24-hour nursing for mental health residential treatment centers but only required skilled nursing facilities — an analogous medical facility — to be “duly licensed.” Furthermore, federal and state law allow certain exceptions to 24-hour nursing requirements for skilled nursing facilities, meaning the rules were not applied equally.

Similarly, the court found that the blanket exclusion for “wilderness programs” applied only to behavioral health services but had no equivalent restriction on medical or surgical intermediate care facilities — a potential parity violation.

In Conclusion

While the court’s decision only addressed whether the plaintiff’s complaint raised cognizable claims, the decision reinforces that federal law protects individuals seeking mental health and substance abuse treatment from discriminatory insurance practices, and that plan provisions requiring 24-hour onsite nursing for mental health treatment centers may violate federal parity rules.
