STAT+: Massachusetts sues UnitedHealth, alleging fraud in state’s Medicaid plans for seniors

Massachusetts Attorney General Andrea Joy Campbell is suing UnitedHealthcare, a subsidiary of UnitedHealth Group, for allegedly inflating diagnoses of low-income seniors in the state’s Medicaid program to secure at least $100 million in fraudulent payments. The lawsuit claims the company used deceptive upcoding practices over the past decade, marking one of the first such cases targeting dual eligibles enrolled in both Medicare and Medicaid.
