UnitedHealthcare Under Fire as Massachusetts Alleges $100M Fraud

Massachusetts Attorney General Andrea Campbell has filed a major lawsuit against health insurance giant UnitedHealthcare, accusing the company of defrauding the state’s Medicaid program, MassHealth, out of more than $100 million over the last decade. The lawsuit alleges that UnitedHealthcare systematically manipulated the health assessments of elderly patients in order to receive higher payments from taxpayers, raising serious questions about how some managed-care programs operate.

The legal action, filed in Suffolk Superior Court, claims that the insurer intentionally made thousands of seniors appear sicker than they actually were, allowing the company to collect inflated reimbursements through MassHealth’s Senior Care Options (SCO) program. State officials describe the alleged scheme as a long-running effort that prioritized profits over program integrity.

What Is the MassHealth Senior Care Options Program?

The lawsuit centers on MassHealth’s Senior Care Options program, which serves Massachusetts residents aged 65 and older who qualify for both Medicaid and Medicare benefits. Under the program, participating insurers receive monthly payments based on the medical needs of enrolled members. Patients are assigned one of three care levels, with higher levels resulting in larger payments from the state.

Level 1 represents members with the least complex medical needs, while Level 3 is reserved for patients requiring the most extensive care and services. Because reimbursement rates increase significantly with higher classifications, insurers have a financial incentive to ensure assessments accurately reflect patient conditions.

According to state officials, UnitedHealthcare abused this system by inflating members’ health conditions and assigning them to higher reimbursement categories than warranted.

Allegations of “Upcoding” and Misrepresentation

At the heart of the lawsuit is a practice known as “upcoding,” where a healthcare organization exaggerates the severity of a patient’s medical condition to obtain higher payments.

Attorney General Campbell alleges that from 2015 through 2025, UnitedHealthcare manipulated health assessments to make members appear more seriously ill than they actually were. The state claims the insurer submitted diagnoses that lacked medical support and classified members into higher care categories despite insufficient evidence.

One allegation involves behavioral health diagnoses. According to the lawsuit, United classified some members as having conditions such as anxiety or depression even though those individuals lacked corresponding diagnoses, treatments, or behavioral health histories. By doing so, the company allegedly qualified these members for Level 2 classifications that generated higher payments from MassHealth.

The lawsuit also claims United improperly assigned many seniors to Level 3—the highest reimbursement category—even though they did not meet the program’s requirements for that level of care.

Internal Reviews Allegedly Revealed Problems

One of the most damaging allegations in the complaint involves UnitedHealthcare’s own internal audits.

According to the Attorney General’s office, internal reviews conducted in 2018 and 2019 identified numerous members who had been improperly classified as Level 3 patients. After discovering these issues, the company allegedly downgraded many members to lower levels of care. However, the state claims United never informed MassHealth that it had previously received inflated payments for those individuals and never returned the excess funds.

The lawsuit argues that this failure to disclose overpayments contributed significantly to the more than $100 million in alleged losses suffered by the state’s Medicaid program.

Former Nurses Reportedly Raised Concerns

The Attorney General’s investigation reportedly relied in part on information provided by former nurses who worked within the program.

According to the complaint, several nurses alleged that UnitedHealthcare encouraged practices that resulted in inflated diagnoses and inaccurate assessments. Some reportedly stated that patient evaluations included information copied and pasted from previous assessments, potentially creating inaccurate records that did not reflect a patient’s actual medical condition.

The lawsuit further alleges that chronic understaffing placed pressure on nurses and assessment teams, creating incentives to classify patients as having more severe health conditions than they truly had. Campbell’s office argues that these practices were not isolated mistakes but part of a broader strategy aimed at increasing revenue.

A $133,000 Example Cited in the Complaint

State investigators included specific examples in their filing to illustrate the alleged misconduct.

One patient was reportedly classified as requiring extensive assistance with daily activities such as bathing, dressing, and grooming while managing conditions including Type 2 diabetes, hypertension, and arthritis. According to the lawsuit, the individual was largely independent and managed symptoms with minimal intervention.

The Attorney General’s office alleges that this classification resulted in approximately $133,000 in excessive payments over a five-year period.

Officials argue that such cases demonstrate how inaccurate assessments could generate substantial overpayments when repeated across a large population of enrolled seniors.

Attorney General Campbell’s Response

Attorney General Andrea Campbell has described the allegations as serious and intentional.

“The state’s managed care plans need to act in good faith on behalf of their members and the financial resources of our state’s Medicaid program,” Campbell said when announcing the lawsuit. She stated that her office’s investigation found that UnitedHealthcare knowingly manipulated health assessments to increase profits.

Campbell emphasized that taxpayer-funded healthcare programs depend on accurate reporting and that companies participating in those programs must be held accountable when they fail to meet their obligations.

UnitedHealthcare Denies Wrongdoing

UnitedHealthcare strongly disputes the allegations.

In a statement, the company called the lawsuit “meritless” and argued that the Attorney General’s claims misrepresent the purpose and operation of the Senior Care Options program. The insurer maintains that its assessments are designed to ensure seniors with complex healthcare needs receive appropriate services and support.

The company also stated that state officials are incorrect in suggesting that vulnerable seniors should not receive the level of care that UnitedHealthcare helps coordinate.

As the case moves through the court system, UnitedHealthcare is expected to vigorously defend its practices and challenge the state’s claims.

Potential Financial Consequences

The lawsuit seeks more than simple repayment of the alleged overcharges.

Massachusetts is pursuing damages under claims that include false claims, breach of contract, and unjust enrichment. If the state prevails, the company could be required to repay the disputed funds and potentially face triple damages under applicable laws.

Given the size of the alleged fraud, the financial exposure could reach hundreds of millions of dollars. The outcome may also influence future oversight of Medicaid managed-care programs both within Massachusetts and across the country.

Broader Implications for Healthcare

The lawsuit arrives at a time when healthcare spending continues to rise and government agencies are increasing scrutiny of insurance billing practices. MassHealth alone represents one of the largest expenditures in the Massachusetts state budget, with spending growing substantially in recent years.

If the allegations are proven, the case could become one of the most significant Medicaid fraud actions ever brought against a major health insurer in Massachusetts. For now, however, the claims remain allegations, and the court process will determine whether UnitedHealthcare engaged in the conduct described by state officials.

As legal proceedings move forward, both policymakers and healthcare advocates will be closely watching a case that could reshape how insurers document patient conditions and receive payments from publicly funded healthcare programs.
