Therapy, medication, or residential treatment denied? The Mental Health Parity Act requires equal coverage.

Federal parity law and the ACA give mental health patients the same coverage rights as those with physical conditions.
The Mental Health Parity and Addiction Equity Act (MHPAEA) requires that coverage limits, prior authorization requirements, and treatment limitations for mental health and substance use disorders be no more restrictive than those applied to medical or surgical benefits. If your plan covers unlimited physical therapy but limits therapy sessions, that is a parity violation.
The Affordable Care Act classifies mental health and substance use disorder services as one of ten essential health benefits that all marketplace and small employer plans must cover. This includes outpatient therapy, inpatient psychiatric care, prescription medications, and substance use treatment. Denials based on blanket exclusions are illegal.
In the landmark Wit v. United Behavioral Health ruling, a federal court found that UBH's internal guidelines were improperly more restrictive than generally accepted standards of care. This case established that insurers must use clinically recognized criteria (like LOCUS or ASAM) — not internally developed cost-saving guidelines — to make coverage decisions.
Many states go further than federal MHPAEA, mandating specific session counts, residential treatment coverage, and telehealth parity. States like California, New York, and Illinois have their own enforcement agencies. If your federal claim fails, a parallel state parity complaint can apply additional pressure on your insurer to reverse the denial.
