Consulting firm Deloitte has become a dominant player in the government business sector by supplying eligibility system technology to states, specifically for Medicaid coverage. An investigation by KFF Health News revealed that these systems, which have cost 25 states at least $5 billion, are often plagued by errors and malfunctions. Issues include generating incorrect notices to beneficiaries, sending paperwork to wrong addresses, and system freezes. These errors have significant consequences, such as one Tennessee mother losing her coverage just before surgery to relieve anemia. America's poorest residents are particularly affected by these system failures.
