We’ve previously blogged about the Mental Health Parity Act. This law forbids insurers from discriminating against mental health and substance addiction by covering treatment for those conditions less favorably than other medical treatment. A 2022 report noted insurers continue to violate this law.
A new Washington Supreme Court ruling restricts individuals’ ability to enforce this law. On December 21, 2023, the court ruled in P.E.L. v. Premera Blue Cross that the plaintiffs could not sue their health insurer for excluding certain mental health treatment.
In that case, two parents sued Premera Blue Cross for failing to cover their child’s mental health and substance abuse treatment. The child’s symptoms were so severe they required inpatient hospitalization. The child spent two months at a “wilderness therapy” program before transitioning to long-term treatment.
Premera denied coverage for the wilderness therapy program. The insurance policy generally covered “residential treatment” for mental health conditions. But it specifically excluded any kind of “wilderness” or similar therapy.
The parents alleged that exclusion violated the Mental Health Parity Act and its Washington State counterpart. The Washington Supreme Court disagreed.
The court acknowledged that mental health parity laws aim to fix a long history of discrimination against people diagnosed with mental health disorders which has manifested in the insurance industry. Insurance policies historically singled out these diagnoses for worse coverage. They charged higher premiums and provided lower benefits for them.
These laws began in 1996 with the federal Mental Health Parity Act and continued through Congress’ enactment of the Affordable Care Act in 2016, which included protections for mental health coverage. Washington State also enacted similar legislation in 2005.
The court found that the plaintiffs could not sue for violations of the federal laws. Congress decided not to include a private right of action with that legislation. So the plaintiffs could not pursue violations of those laws by alleging they became part of their insurance policy contracts.
The court also found the parents could not sue for violation of the Washington State version of these laws. Washington State’s mental health parity laws require insurance to cover mental health services equally. That means insurance must provide equal copays, out of pocket limits, deductibles, and similar provisions to mental health diagnoses as they do to other conditions.
In particular, the state law says that insurers cannot impose special exclusions for medically necessary mental health treatment. The parents argued Premera violated that rule when it refused to cover their child’s wilderness therapy without deciding it wasn’t medically necessary.
The problem for the parents is that the state parity law excludes “residential treatment” from these protections. Since “wilderness” therapy is a form of residential treatment, the parity law didn’t apply.
