The Policy Change
The Arizona Health Care Cost Containment System (AHCCCS), the state’s Medicaid agency, is facing a second lawsuit concerning contract disputes between insurance companies and prominent autism therapy centers. On February 6, parents of 11 children diagnosed with autism spectrum disorder filed a class-action lawsuit against AHCCCS. This complaint alleges that the agency unlawfully approved modifications to the provider networks of two insurers, Mercy Care and Arizona Complete Health, which led to significant disruptions in applied behavior analysis (ABA) therapy for their children.
This latest legal action follows an initial lawsuit filed on December 15 by families and Centria Autism Center against AHCCCS, Mercy Care, and the Department of Economic Security. Both lawsuits were triggered by Mercy Care and Arizona Complete Health terminating their contracts with Centria Autism and Action Behavior Centers (ABC). These terminations have compelled numerous families to seek new providers for their children’s essential ABA therapy services.
According to Tim Nelson, attorney for the 11 families in the class-action suit, AHCCCS’s decision to permit these private insurers to prioritize profits over the treatment of low-income children with autism is alarming. Nelson highlighted that these companies have historically struggled to maintain sufficient autism providers for Medicaid beneficiaries, resulting in already extensive waiting lists for families. Centria and ABC contend that Mercy Care terminated their contracts after attempting to reduce reimbursement rates for services without engaging in good-faith negotiations. Arizona Complete Health also terminated its contract with ABC around the same period, with ABC staff asserting the termination was without cause. The class-action suit further alleges that Arizona Complete Health has failed to adequately assist patients in finding alternative therapy providers.
Impact on ABA
The core of the families’ concern, as detailed in the lawsuits, revolves around the profound impact of these disruptions on children with autism spectrum disorder, who are highly sensitive to changes in routine and environment. Parents of children receiving services from Centria and ABC have reported that their children have experienced regression in skills and behaviors due to the abrupt changes in their ABA therapy. The class-action suit argues that parents’ resistance to switching ABA providers is not merely an “emotionally charged preference,” as AHCCCS attorneys suggested in earlier court filings, but is rooted in substantial logistical challenges. These challenges include difficulties with transportation, a severe scarcity of providers with openings in rural areas, and a reduction in available therapy hours.
AHCCCS, in its defense during the first lawsuit, asserted that Mercy Care possessed openings for both clinic-based and in-home ABA services for over 1,000 members, a number exceeding those losing access to Centria and ABC. The agency’s attorneys argued that the individual plaintiffs’ concerns, while understandable, did not constitute “irreparable injury.” However, the plaintiffs in the class-action suit counter that allowing insurers to terminate contracts with ABA providers not only violates state and federal law but also sets a dangerous precedent that could lead to a widespread wave of similar contract terminations across Arizona, further jeopardizing access to care.
Next Steps
The contract terminations are scheduled to become effective in March, leaving families with a limited timeframe to secure new providers or find alternative insurance coverage for their children’s ABA therapy. Both lawsuits have requested the court to issue temporary stays on these effective dates while the legal proceedings unfold. As of the reporting, no rulings have been issued on these critical requests in either case, leaving the future of ABA access for many Arizona families in uncertainty.
