Opinion

IN THE UNITED STATES DISTRICT COURT FOR THE WESTERN DISTRICT OF WISCONSIN

R.S., individually and on behalf of A.S., a minor,

Plaintiff, OPINION AND ORDER v. 22-cv-418-wmc QUARTZ HEALTH BENEFIT PLANS CORPORATION,

Defendant.

Plaintiff R.S. filed this action under the Employee Retirement Income Security Act (“ERISA”), 29 U.S.C. §§ 1001–1491, against defendant Quartz Health Benefit Plans Corporation, the benefit claims administrator for plaintiff’s employee-sponsored health benefits plan. In particular, plaintiff claims that Quartz violated ERISA by denying coverage for his son’s residential treatment for mental health and substance abuse in violation of the terms of his health benefits plan and the Mental Health Parity and Addiction Equity Act. The parties’ cross motions for summary judgment are pending before the court. (Dkt. #22 and Dkt. #26.) For the reasons discussed below, the court finds that Quartz’s benefits determination was arbitrary and capricious and violated ERISA. Therefore, at summary judgment, plaintiff’s motion will be granted and Quartz’s motion will be denied with respect to R.S.’s ERISA claim, and the case will be remanded to Quartz for further proceedings consistent with this opinion. However, the court will grant defendant’s motion as to plaintiff’s claim under the Mental Health Parity and Addiction Equity Act. UNDISPUTED FACTS1 A. The Parties Plaintiff R.S. was a participant in an employee health benefit plan insured and

administered by defendant Quartz Health Benefits Plan Corporation (“the Plan”). His son, A.S., was R.S.’s covered dependent under the same plan. The plan granted Quartz discretion to interpret and apply that plan’s terms, limitations and exclusions in making benefits determinations.

B. The Health Benefit Plan The Plan provides coverage for “Behavioral Health and Substance Abuse Services,” which it defines as:

The treatment of psychiatric Illness or substance use disorders. This treatment is provided on an inpatient, outpatient, transitional and emergency care basis. (R. 103.) However, the Plan only covers Behavioral Health and Substance Abuse Services that are “Medically Necessary,” which it defines as “Health care services or supplies needed to prevent, diagnose or treat an Illness, Injury, condition, disease or its symptoms and that meet accepted standards of medicine.” (R. 113.) The Plan excludes treatment that is not medically necessary, which it defines as “Any service that is not required in accordance with accepted standards of medical, surgical or psychiatric practice.” (R. 144.)

1 The following facts are drawn from the parties’ proposed findings of fact and responses, as well as the underlying evidence submitted by the parties, and are deemed undisputed for purposes of summary judgment unless otherwise noted. Citations to (R.) are to the administrative record. (Dkt. #17.) The Plan further identifies the relevant factors in making a “Medically Necessary” determination as: 1. Consistent with the symptoms or diagnosis and treatment of a Member’s Illness or Injury;

2. Appropriate under the standards of acceptable medical practice to treat that Illness or Injury;

3. Not solely for the convenience of the Member, Physician, Hospital or other health care Provider;

4. The most appropriate supply or level of service that can be safely provided to the Member and which accomplishes the desired end result in the most economical manner; and

5. Not primarily for cosmetic improvement of the Member’s appearance, regardless of psychological benefit. (R. 113.) The Plan also contemplates that while the “Member’s Attending Physician makes decisions regarding service and treatment,” a “physician appointed by Quartz” will “serve as the Plan’s final decision-maker” -- defined as the Plan’s “Medical Director” -- and be vested with the authority and discretion to make determinations on what “service, treatment, procedure, drug, device or supply” is “Medically Necessary and eligible for coverage under the Plan.” The Plan, through its Medical Director, using criteria developed by Medical Management and other recognized sources, has the authority to determine whether a service, treatment, procedure, Prescription Drug, device or supply is Medically Necessary and eligible for coverage under the Plan. (R. 112–13.) During the relevant time period, Quartz relied on the screening guidelines known as InterQual Criteria for Child and Adolescent Psychiatry (“InterQual criteria”) to review the medical necessity of a minor’s inpatient treatment at a residential treatment facility.

InterQual screening guidelines for inpatient treatment at a residential treatment facility are divided into two groups: (1) those designated for screening treatment for an eating disorder; and (2) those designated for screening treatment for a “serious emotional disturbance or autism spectrum disorder or intellectual disability.”2 The InterQual criteria are further divided by length of stay: (a) initial admission/week one; (b) week two criteria;

and (c) extended stay criteria for inpatient stays of three weeks or more. For an “extended stay” under (c) at a residential treatment facility, the InterQual criteria provide screening guidelines to determine if the patient is considered “not clinically stable for discharge,” including a list of symptoms demonstrated within the last week. In particular, at week three or more, InterQual’s guidelines included the following list of symptoms, which if displayed within the last week, demonstrate clinical instability:

“aggressive or assaultive behavior; angry outbursts; depersonalization or derealization; destruction of property; easily frustrated and poor impulse control; homicidal ideation without intent; hypervigilance or paranoia; nonsuicidal self-injury; persistent rule violations; psychiatric medication refractory or resistant and symptoms increasing or persisting; psychomotor agitation or retardation; runaway from facility or while on home pass; sexually inappropriate; or suicidal ideation without intent.”

2 Quartz apparently applied the InterQual criteria for “serious emotional disturbance or autism spectrum disorder or intellectual disability” for substance abuse disorders, as well as other mental and behavioral health issues. C. A.S.’s Residential Treatment Since kindergarten, A.S. has struggled with behavioral and mental health difficulties. He was diagnosed with attention deficit hyperactivity disorder in fifth grade;

and later in high school, he was diagnosed with an “extreme” case of “oppositional defiant disorder.” As a teenager, A.S. engaged in oppositional, disruptive, violent and increasingly dangerous and destructive behaviors, and eventually began using and selling drugs and was involved in gang activity, stealing, absenteeism, fighting with his classmates and others, threatening physical violence against his parents, run-ins with the police, and other criminal behaviors. Relatedly, A.S. was failing his classes and had thoughts of killing

himself. During the Covid-19 pandemic in particular, when he was attending school from home, he used drugs nearly every day, and stole hundreds to thousands of dollars from his parents. When confronted, A.S. also attacked his father, destroyed parts of his car, and threatened to have his friends kill him. After therapy and other interventions were unsuccessful, A.S.’s therapist recommended that his parents consider inpatient treatment options.

On September 17, 2020, A.S. was admitted to Triumph Youth Services, a mental health facility in Brigham City, Utah. When admitted to Triumph, A.S.
