Two advocacy groups are suing Arizona’s Medicaid program over claims of increased and mandatory copayments for low-income adults and childless adults.

The William E. Morris Institute for Justice and the National Health Law Program said in a release Friday they jointly filed a lawsuit earlier this month against state and federal officials in U.S. District Court.

The complaint alleges the federal government unlawfully gave the state permission to impose high copayments. They say these copays violate the Medicaid Act and some beneficiaries could be denied care.

Arizona Health Care Cost Containment System Director Tom Betlach is also named in the lawsuit.

AHCCCS spokeswoman Monica Coury says the agency’s legal counsel has seen the complaint. She says the same attorney has filed previous lawsuits against AHCCCS with the same arguments.
