Massachusetts filed a lawsuit Friday against UnitedHealthcare, accusing the insurer of fraudulently obtaining more than $100 million [1] in Medicaid payments.
The legal action targets the practice of "upcoding," where insurers make patients appear sicker than they are to secure higher government reimbursements. Because Medicaid funding for elderly and disabled patients is tied to the severity of their diagnoses, manipulating these records can artificially inflate corporate revenue at the expense of public funds.
Attorney General Andrea Joy Campbell filed the suit against the insurance subsidiary of UnitedHealth Group [1]. The complaint alleges that the company targeted low-income elderly patients within the state's Medicaid program, known as MassHealth [2].
According to the filing, UnitedHealthcare engaged in a scheme to inflate diagnoses for these members [2]. By making these patients appear more seriously ill, the company allegedly secured higher payments from the state [2]. The total amount the state claims was fraudulently obtained exceeds $100 million [1].
This litigation focuses on the integrity of risk-adjustment models used in government-funded healthcare. When insurers misrepresent the health status of their members, it can distort the financial landscape of public health programs, potentially leading to higher costs for taxpayers and misallocated resources for patient care.
The lawsuit was filed on May 29, 2026 [2]. It represents a significant effort by the state to recover funds it believes were obtained through deceptive billing practices.

This lawsuit highlights a growing tension between private insurers and state governments over the accuracy of risk-adjustment data. If the state proves that UnitedHealthcare systematically inflated diagnoses, it could lead to stricter auditing requirements for all Medicaid managed care organizations and potentially trigger similar investigations in other states using similar payment models.
