Delaware patients with private health insurance may soon see expanded access to mental health and substance use disorder treatment under the Fair Standards Mental Health Care Act. The legislation, which passed both the state House and Senate in June 2026, mandates that insurers adopt evidence-based clinical standards and eliminates many prior authorization hurdles for mental wellness services, according to the bill’s text.
How the Fair Standards Mental Health Care Act Changes Coverage
The act aims to close the gap between mental health coverage and traditional medical services by requiring insurance carriers to align their policies with independent, clinical “gold-standard” guidelines. According to the bill, this includes standards set by organizations like the American Academy of Child and Adolescent Psychiatry. Insurers will be required to cover all medically necessary services, including emergency care and inpatient treatment, without the bureaucratic delays often associated with prior authorization.

Delawareans are currently five times more likely to seek out-of-network mental health care compared to primary care, leading to significantly higher out-of-pocket costs for families, according to data cited in the legislation.
What Defines “Serious Mental Illness” Under the New Rules?
Following the passage of House Amendment 1 on June 9, 2026, the law creates a distinction between general mental health care and “serious mental illness.” Under the amendment, carriers may still require precertification or prior authorization for disorders not classified as “serious.” Legislators defined serious mental illness to include conditions such as schizophrenia, bipolar disorder, eating disorders, and neurodevelopmental disorders, among others. Diagnostic criteria must be determined using the most recent edition of the Diagnostic and Statistical Manual of Mental Disorders.
Why Parity Matters for Patients
The legislation introduces a “nonquantitative treatment limitation parity analysis,” a process that forces health plans to prove that barriers like step therapy are no more restrictive for mental health than they are for surgical or medical benefits. According to the U.S. Department of Labor, this documentation must be provided to providers and patients free of charge upon request. By requiring this transparency, the state aims to stop the common practice of families paying out-of-pocket for services that should be covered by their existing insurance premiums.
If you struggle to get mental health coverage approved, ask your insurer for their “nonquantitative treatment limitation” documentation. Under this new state framework, they are required to justify why mental health limits are stricter than those applied to physical health procedures.
What Happens Next for Delaware Policyholders?
The bill currently awaits the signature of Gov. Meyer. If enacted, the requirements will apply to individual, group, and blanket policies issued or renewed after December 31, 2027. The law also mandates that at least one FDA-approved medication for substance use disorders must be placed on the lowest-cost tier of drug formularies, ensuring that life-saving treatments remain affordable for those in recovery.
