In a turn of events that raises more than a few eyebrows, it has come to light that the Chief Medical Officer of Arizona’s Medicaid agency, AHCCCS, Dr. Theresa Costales, has been operating with an expired medical license. According to an alarming discovery by House Republican leaders, Costales, whose license required renewal by April 9, 2025, hadn't completed this fundamental procedural task. Costales has continued to advise on important state health policies despite the lapse, as per a release by the House GOP, found here.
The implications of this oversight are not slight, considering the individual in question oversees the healthcare services of over 2 million Arizonans. This information is disturbing by any measure, given that the role of the CMO includes acting as an expert witness for the state and influencing clinical policies that can have far-reaching effects on patients' lives. Holding an active license is typically non-negotiable for such positions—something that's even enforced as a pre-employment condition in departments akin to AHCCCS, like the Arizona Department of Corrections.
"A lapse like this should never happen in a healthcare agency responsible for millions of people," Speaker of the House Steve Montenegro expressed, reflecting the exasperation of many. The Republicans point to the situation as a stark failure of diligence on the Governor Katie Hobbs’ administration's part, potentially eroding public trust in the state's healthcare leadership. House Majority Leader Michael Carbone highlighted the simplicity of license verification, a task that any citizen can quickly undertake online, emphasizing how egregious it is that such a blunder could have been missed at the uppermost level of medical leadership.
Adding to the chorus of disapproval, House Majority Whip Julie Willoughby commented on the potential ramifications this might have on vulnerable groups, specifically questioning the integrity of recent HCBS assessments overseen by a possibly unlicensed CMO. "You cannot have a Chief Medical Officer without an active license—it’s that simple," she said, questioning whether there was something more nefarious at play with the license not being renewed. Given the sensitive nature of assessments affecting the developmental disabilities community, Willoughby's concerns underscore the gravity of Costales' expired medical license.
Finally, Speaker Pro Tempore Neal Carter condemned what he saw as another misstep by Governor Hobbs's administration. He emphasized the scale of the mistake's impact, saying, "This isn’t a small oversight—it undermines public confidence in one of Arizona’s largest healthcare agencies. Arizonans deserve better." From the Republicans' viewpoint, the lack of a current medical license for the head of such a crucial healthcare entity is unacceptable, necessitating immediate investigation and action.
