Mental Health Parity and the Real Test of Employee Benefits
New federal guidance puts the focus on how employees actually access care. Here is what employers should be asking.
Imagine an employee who finally decides to seek treatment for depression. The benefits summary shows coverage. The provider directory lists clinicians. Yet the first several calls lead to closed practices, unavailable appointments or providers who no longer accept the plan.
For that employee, the value of the benefit depends on what happens next. Who helps find care? What will it cost? Will another administrative hurdle stand in the way?
Those questions give employers a useful starting point for understanding mental health parity—and why it deserves attention beyond the annual benefits renewal.
On September 8, 2026, the U.S. Department of Labor issued Field Assistance Bulletin No. 2026-03, identifying three priorities for enforcing the nonquantitative treatment limitation requirements of the Mental Health Parity and Addiction Equity Act, or MHPAEA. The priorities are treatment exclusions, medical necessity reviews and network adequacy standards. The agency can also investigate other limitations, particularly following participant complaints.
The rules behind the benefits summary
For plans subject to MHPAEA, parity generally means mental health and substance use disorder benefits cannot face more restrictive requirements than medical and surgical benefits. Copays and visit limits are part of the picture. So are the less visible rules that determine whether someone can receive treatment.
These rules are called nonquantitative treatment limitations, or NQTLs. They include prior authorization requirements, medical necessity standards and criteria for admitting providers to a network. The applicable processes and standards must be comparable to, and applied no more stringently than, those used for medical and surgical benefits within the same benefit classification.
A reassuring benefits summary cannot establish that these requirements are being met. Plans and insurers must perform and document comparative analyses of relevant NQTLs, examining both their design and application.
Three places to look more closely
Start with exclusions. A plan might cover nutritional counseling for diabetes while excluding it for an eating disorder. Or it might exclude certain therapies for autism while covering similar services for medical conditions. These are warning signs that warrant a closer comparison, rather than an automatic conclusion that every exclusion violates the law.
Next, examine the path to approval. Does behavioral health treatment require repeated reviews or extra documentation that comparable medical care does not? Does nearly every mental health service require prior authorization, while few medical services in the same classification do? The practical question is whether the plan places additional hurdles in the way of one category of care.
Finally, look at the network. A directory is only a starting point. Ask how providers join the network, how reimbursement methodologies are developed and what assistance is available when an employee cannot find an appropriate participating provider. Difficulty scheduling an appointment does not, by itself, establish a parity violation. It does provide a reason to examine the underlying standards and the employee’s options.
What the enforcement relief actually means
Employers may have heard that federal agencies paused enforcement of newer parity regulations. The September bulletin confirms that DOL will not enforce provisions of the 2024 final rule that are new relative to the 2013 rule. Existing statutory obligations (including the comparative analysis requirements added by Congress in 2021) continue to apply. The bulletin describes an enforcement approach; it does not replace the underlying law. See the bulletin’s explanation.
Turn a renewal conversation into a working review
Employers do not need to become clinical reviewers to ask better questions. A productive conversation with the carrier, administrator and benefits advisor can begin with five:
Which parity analyses apply to our specific plan, and can we obtain them?
Who prepares and updates the analyses, particularly if we customize benefits or use a separate behavioral health administrator?
What happens when an employee cannot locate an available in-network provider
What reporting can help us identify recurring access problems, denials or out-of-network use?
Who will assist during a parity investigation, and is that support included in our agreement?
These questions draw on the service-provider discussion points accompanying DOL’s guidance. The answers should lead to clear responsibilities, accessible documentation and a process for resolving concerns. A general assurance that a vendor “handles compliance” leaves too much unanswered.
As a practical next step, assign someone to coordinate that follow-through. Keep a record of questions, responses and unresolved issues, and revisit them when coverage or administrators change. Give employees a clear route to benefits assistance so an access problem reaches someone who can help.
