The Policy Change
A significant legal challenge has emerged in Arizona, with Centria Autism, a major provider of Applied Behavior Analysis (ABA) therapy, joining two parents of children with autism spectrum disorder in a lawsuit against the Arizona Health Care Cost Containment System (AHCCCS), its managed care organization (MCO) Mercy Care, and the Department of Economic Security (DES). Filed on December 15, the complaint alleges that Mercy Care unilaterally and erroneously terminated its contract with Centria on October 17, following Centria’s refusal to accept a substantial 25% decrease in reimbursement rates. This proposed reduction came just months after Mercy Care had already implemented a 15% rate cut for ABA providers.
The lawsuit contends that Mercy Care failed to engage in good faith negotiations regarding the reimbursement rates, which Centria deemed unsustainable and detrimental to the quality of services provided. Furthermore, the plaintiffs accuse AHCCCS and DES, which oversees the state’s Division of Developmental Disabilities (DDD), of failing to adequately ensure continuity of care for affected patients. The complaint specifically highlights that neither Mercy Care nor AHCCCS provided a written transition plan to help parents identify alternative providers or switch to a different MCO to continue services with Centria practitioners.
Impact on ABA
The contract dispute has immediate and severe implications for approximately 700 children receiving ABA services from Centria across Arizona, with nearly 300 of these children covered by Mercy Care’s health plan. The state is already grappling with a significant ABA provider shortage, with an estimated 22,000 children unable to access necessary services statewide. The lawsuit underscores the vulnerability of children with autism to changes in their therapy routines, warning of a clear risk of regression and harm if services are interrupted.
Parents involved in the lawsuit, like Tiana Brandon, have expressed frustration with AHCCCS and DDD for their perceived lack of assistance in finding new providers or health plans for their children. The complaint argues that the best-case scenario for these children could involve a six-month wait before receiving services from a new provider, a delay that poses substantial developmental risks. The legal action also alleges that AHCCCS actively prevented some Centria patients, including Brandon’s son, from switching to a different MCO, thereby hindering their ability to maintain therapy with their current providers.
Next Steps
In addition to the primary lawsuit, Centria and the parents filed a motion for a temporary restraining order (TRO), seeking to prevent the contract termination from taking effect in March and to halt any attempts to transition Centria patients to other providers. A hearing on this motion was scheduled for December 19. Spokespersons for Mercy Care, AHCCCS, and DES have issued statements in response to the litigation. Mercy Care stated its confidence in its provider network and its ability to ensure continuity of care, without directly addressing the lawsuit’s specifics. AHCCCS acknowledged awareness of the lawsuit, confirming it is reviewing the allegations and reiterating that ABA is a covered, medically necessary service. DES declined to comment on ongoing litigation.
This legal battle highlights broader systemic challenges within the Medicaid landscape concerning ABA therapy, including the delicate balance between cost containment for MCOs and ensuring adequate access and sustainable reimbursement rates for providers. The outcome of this case could set a precedent for how contract disputes are managed and how state agencies are held accountable for maintaining essential healthcare services for vulnerable populations.
