Behavioral Health Benefit Coverage and Wit 
v. United Behavioral Health 
December 21, 2022 
The National Institute of Mental Health estimates that nearly 53 million American adults live with a 
mental illness, and about 24 million (46.2%) received treatment in 2020. The demand for behavioral 
health services, including mental health and substance use disorder (SUD) treatment, also increased 
during the COVID-19 pandemic. As a result, access to and coverage for behavioral health services has 
been a priority for many in the 117th Congress.  
This Legal Sidebar discusses the U.S. Court of Appeals for the Ninth Circuit’s decision in Wit v. United 
Behavioral Health, which could have implications for individuals with private health insurance plans who 
are seeking behavioral health coverage. Some stakeholders anticipate that the case’s disposition could 
affect private insurance patients’ access to mental health and SUD treatment nationwide. 
Background 
Wit was brought as a class action in the U.S. District Court for the Northern District of California 
against United Behavioral Health (UBH), one of the largest behavioral health plan administrators 
in the country. At issue in the case is whether UBH may use internal guidelines, which are not 
based on generally accepted standards of care (GASC), to guide its behavioral health care 
coverage determinations (i.e., its decisions as to whether the plan’s covered benefits are 
medically necessary, and coverable, for the given enrollees that sought the treatments). 
According to plaintiffs and the amici curiae, it has become common practice for plan 
administrators to base coverage decisions, at least in part, on internally developed guidelines as 
UBH did in Wit.  
 
Although plan administrators owe fiduciary duties to their enrollees, federal law does not require private 
health insurers (or benefit administrators such as UBH) to base their benefit coverage decisions on GASC. 
Federal law does not define GASC, and there is no universal clinical definition. Instead, the district court 
in Wit looked at a variety of sources to determine the GASC, including the American Society of Addiction 
Medicine (ASAM) Criteria, which the court found are ”the most widely accepted articulation of the

generally accepted standards of care for how to conduct a comprehensive multidimensional assessment of 
a patient” with a SUD.  
The three classes of plaintiffs in the Wit case comprise more than 60,000 people, all of whom were denied 
behavioral health benefits under their plans’ terms when UBH determined, based at least in part on its 
internal guidelines, that the requested behavioral health treatment was not medically necessary. Plaintiffs 
were denied coverage for a range of services, including inpatient hospitalization for mental health 
treatment, inpatient SUD treatment, and outpatient treatment, including psychotherapy services. The 
plaintiffs are all beneficiaries of employer-sponsored health plans with behavioral health benefits 
administered by UBH. The Employee Retirement Income Security Act (ERISA) governs all of the plans. 
There are three distinct classes of plaintiffs, one of which is composed of beneficiaries whose plans are 
governed by both ERISA and the state laws of Connecticut, Illinois, Rhode Island, and Texas. These 
states require plan administrators to base coverage decisions on GASC.  
Plaintiffs sued UBH under Section 502 of ERISA, which, in part, allows employee benefit plan 
participants and beneficiaries to sue their plan administrator to recover benefits due under the plan or 
otherwise enforce the plans’ terms. Plaintiffs alleged UBH breached its fiduciary duty to administer the 
plans in the beneficiaries’ interest by “prioritizing cost savings over members’ interests.” Plaintiffs also 
argued that UBH’s denials of their claims constituted an arbitrary and capricious denial of benefits. 
Plaintiffs have emphasized that the case does not concern whether the beneficiaries were actually entitled 
to benefits, but rather whether plan administrators may use internal guidelines that are inconsistent with 
GASC as a basis for claim denials. 
District Court Decision 
The district court issued a decision on March 5, 2019, finding that UBH breached its fiduciary duty to 
plaintiffs by violating the duties of loyalty, due care, and compliance with plan terms by relying on 
unreasonable guidelines that do not adhere to GASC. The court further ruled in plaintiffs’ favor on the 
denial-of-benefits claim, finding that “UBH’s Guidelines were unreasonable and an abuse of discretion, 
because they were more restrictive than [GASC].” The court further found that UBH violated the state 
laws of Illinois, Connecticut, Rhode Island, and Texas by not adhering to GASC when making benefit 
determinations. The district court ordered UBH to reprocess more than 60,000 claims, all of which were 
initially denied on the basis that they were not medically necessary under UBH’s internal guidelines.  
The Appropriate Standard of Review and UBH’s Conflict of Interest 
A central issue in Wit is whether UBH breached its duty to the plan beneficiaries. District courts review 
the question of whether a breach of duty occurred under an abuse-of-discretion standard. The U.S. 
Supreme Court has held that under that standard, a plan administrator’s decision is entitled to deference 
and should be upheld if it is reasonable. The Supreme Court (as well as a lower circuit court) has also 
acknowledged, however, that some degree of skepticism regarding the plan administrator’s decision to 
deny benefits is warranted when there is evidence of a conflict of interest. In Wit, the court found UBH’s 
conflict of interest clear and said that as a result, “significant skepticism is warranted in determining 
whether UBH abused its discretion when it adopted the guidelines.” According to the district court, the 
“most striking” indicator of UBH’s abuse of discretion was its refusal, for which it had no clinical 
justification, to adopt the ASAM Criteria. The court identified several facts indicating that UBH’s 
guidelines were driven by financial considerations. For example, the court emphasized a decision of 
UBH’s CEO not to amend the guidelines to broaden the coverage for Applied Behavior Analysis, a 
common treatment for autism spectrum disorder, citing “business implications,” even after the company’s 
Utilization Management Committee had approved the change.

UBH’s Guidelines Fell Short of Generally Accepted Standards of Care 
In deciding that UBH abused its discretion under the plan by denying benefit claims using its internal 
guidelines, the court first clarified that UBH’s internal guidelines were not part of the terms of plaintiffs’ 
plans, but rather that UBH used them “as objective criteria for making standardized decisions about 
coverage.” The court then conducted a thorough analysis of whether the guidelines adhered to the GASC. 
The court reviewed the sources of GASC, particularly the ASAM Criteria, and made factual findings with 
respect to the GASC for treatment of mental health and SUDs.  
In finding that UBH’s guidelines were not based on medically appropriate standards, the court identified 
several shortfalls, including that they were overly focused on treatment of acute symptoms, rather than 
treatment of chronic conditions and the provision of holistic care. For example, the court noted that the 
guidelines incorrectly necessitated the continuation of acute symptoms in order for the plans to continue 
coverage, observing that the denial of coverage at one level of care did not necessarily mean approval at a 
lower level of care. Other issues identified included that the UBH guidelines required patients to 
“improve within a reasonable time,” and equated “improvement” with “control of acute symptoms,” 
rather than the patient’s holistic improvement. 
The court also found that the UBH guidelines deviated from GASC because they denied coverage if a 
patient demonstrated an unwillingness to participate in treatment, “regardless of whether attempts to 
motivate the patient may eventually be effective or whether it is likely that treatment at this level of care 
is likely to be effective despite the patient’s low motivation.” Further, the court stated that “one of the 
most troubling aspects” of the guidelines is that they do not appropriately address the behavioral health 
needs of children and adolescents. 
The UBH Guidelines Violated State Law 
After determining that the UBH guidelines did not follow medically acceptable standards of care in 
evaluating claims for behavioral health benefit coverage, the court next analyzed whether the guidelines 
violated the state laws of Illinois, Connecticut, Rhode Island, and Texas. Plaintiffs from each of these 
states formed a class, alleging that UBH’s use of internal guidelines that were incompatible with GASC 
violated these states’ laws, which require plan administrators to base coverage denials for SUD treatment 
on lack of evidence of medical necessity on medically appropriate standards. Three of the states require 
UBH to use the ASAM Criteria for determining medically necessary care; Texas requires UBH to use the 
criteria developed by its Department of Insurance. The court found that UBH violated each of these states’ 
laws in using its internal guidelines, because the guidelines were incompatible with GASC.  
Ninth Circuit Decision and Motion for Rehearing 
En Banc 
UBH appealed the district court’s ruling to the Ninth Circuit. On March 22, 2022, the Ninth Circuit issued 
a succinct reversal of the district court. After concluding that plaintiffs had standing to bring their case 
and were a properly certified class, the panel reversed the district court, stating: “While the district court 
noted the correct standard of review, [it] misapplied this standard by substituting its interpretation of the 
Plans for UBH’s.” Further, the panel found that “UBH’s interpretation—that the Plans do not require 
consistency with the GASC—was not unreasonable.” The Ninth Circuit did not evaluate the district 
court’s analysis of whether the Guidelines complied with GASC.  
On May 5, 2022, plaintiffs filed a motion for rehearing en banc, currently pending before the Ninth 
Circuit, arguing that the court’s decision enables plan administrators to more easily deny behavioral

health benefit claims. Plaintiffs argue that the decision “nullifies” state laws requiring insurance 
companies to determine medical necessity by using GASC and that it “gutted the well-established conflict 
of interest doctrine that is vital to protecting ERISA plan participants.” By giving UBH deference, the 
plaintiffs urge that “the panel gave insurers a roadmap for insulating from scrutiny decisions tainted by 
even egregious conflicts of interest.” Plaintiffs also pointed out that almost all states require ERISA plan 
administrators to follow the GASC, and that most insurers use internal guidelines, at least some of which 
are stricter than the GASC, to make those determinations. Plaintiffs insist that allowing UBH to use 
guidelines that are more restrictive than those accepted by the medical community will affect mental 
health and addiction coverage nationwide. Several amici curiae filed briefs in support of plaintiffs, one of 
whom claims the case is an example of how “insurers dig a new—but often illegal—trench, finding new 
ways to deny critically needed behavioral health services.” 
In its response to the plaintiffs’ motion for rehearing, UBH counters that “the panel’s fact-bound, 
unpublished decision fails the ordinary requirements for rehearing, and nowhere approaches the type of 
earth-shattering ruling Plaintiffs portray it as.” UBH emphasizes its discretion to interpret plan terms and 
urges that rehearing is not warranted on the state laws at issue. The company states that many of the 
plaintiffs “likely would not benefit” from having their claims reprocessed anyway, and that the panel’s 
ruling does not interfere with state law because it does not preclude states from enforcing their own 
insurance requirements. UBH also argues that while its guidelines were used to inform decisions of 
medical necessity, consistency with the GASC was merely one of several requirements for a medical 
necessity determination. The Ninth Circuit could rule on the motion for rehearing soon. 
Considerations for Congress 
Congress has a number of options available if it seeks to pursue these issues further. It could wait to 
assess the results of the case that remains pending before considering any potential legislative changes. It 
could instead or in addition amend ERISA to change the amount of deference to which plan 
administrators are entitled when courts review their benefit determinations. In September 2022, the House 
of Representatives passed H.R. 7780, the Mental Health Matters Act, which would amend ERISA Section 
502 to require district courts to review de novo plan administrators’ denial decisions for certain types of 
ERISA health plans. Such a provision could change the outcome of cases brought under Section 502, as it 
would allow district courts to review some plan benefit determinations de novo, rather than giving 
deference to the administrator, as the Ninth Circuit did in the Wit case. 
There is currently no federal requirement that plan administrators base their coverage decisions on GASC. 
As a further option, Congress could amend ERISA to require, as many states have done, that any 
administrator’s internal guidance to evaluate coverage decisions or interpret plan terms be based on 
GASC. If Congress were to do so, it could amend ERISA such that the requirement would apply to all 
types of private health plans.
