The Arizona Health Care Cost Containment System says 2,632 people are affected by the breach.(MGN)

PHOENIX (3TV/CBS 5) — Over 2,600 Arizona Medicaid recipients may have had their personal information stolen after a breach that happened mid-May.

The state’s Medicaid agency, the Arizona Health Care Cost Containment System (AHCCCS), said in a statement that it is “aware of a breach of personal information on May 11, 2023 affecting 2,632 individuals in Arizona who are enrolled Medicaid members.” The vulnerability would have allowed bad actors to see sensitive details, including first and last names, addresses and the last four digits of Social Security numbers through the Health-e-Arizona Plus website. Upon learning of the error, the HEAplus system toolbar was turned off.

AHCCCS assures that this type of breach would not happen again, the agency said in the statement, and that starting July 3, it will start to notify those affected by the breach. The agency will send out the notifications through the mail.

If you learn that you’re affected by the breach, you can contact one of the three credit reporting agencies to report a fraud alert, which lets the agencies know that any new requests for credit may be fraudulent. You can also ask the agencies for a security freeze that stops agencies from releasing your information without your express permission (you’ll have to do this using certified mail notifying all three agencies).

Consumers are entitled to one free credit report from each of the three agencies: Equifax, Experian and TransUnion. You can learn more at or call 1-877-322-8228.
