Massachusetts' top prosecutor has hauled one of the nation’s biggest health insurers into court, accusing it of juicing diagnoses for some of the state’s poorest seniors to squeeze at least $100 million out of MassHealth.
Attorney General Andrea Joy Campbell filed a civil complaint Friday in Suffolk Superior Court against UnitedHealth Insurance Company, which does business as UnitedHealthcare Community Plans of Massachusetts. Her office says the company systematically overstated the medical needs of low-income seniors enrolled in its Senior Care Options plan so it could collect higher payments from the state, enriching itself at taxpayers’ expense.
The filing accuses the insurer of manipulating health assessments to trigger inflated MassHealth reimbursements, according to Mass.gov. The complaint landed in court on Friday, after the case was first detailed in local business coverage by the Boston Business Journal.
How the state says the scheme worked
According to the complaint, UnitedHealthcare repeatedly slotted Senior Care Options members into higher-paying categories, even when medical records did not back up the severity of those classifications. In particular, the company is accused of recording behavioral-health diagnoses that would qualify members for Level 2 payments or labeling people as needing daily skilled nursing care to qualify for Level 3, without corresponding evidence of treatment, The Boston Globe reports.
The Globe notes that Campbell’s office says this pattern ran from January 2015 through December 2025. Internal audits in 2018 and 2019 allegedly flagged coding problems, but the state contends those red flags did not lead to meaningful fixes.
UnitedHealthcare pushes back
UnitedHealthcare is not taking the accusations quietly. The insurer blasted the lawsuit as “meritless” and said it plans to fight the case aggressively, according to Investing.com.
The company has already been under the federal microscope for how it uses diagnostic coding and risk adjustment in its lucrative Medicare Advantage business, scrutiny detailed by STAT. That national backdrop sets the stage for Campbell’s allegations involving dual-eligible seniors who rely on both Medicare and MassHealth.
Why this matters to the state budget
MassHealth is the single largest expense in the state budget, so a nine-figure overpayment allegation lands at a particularly tense fiscal moment on Beacon Hill. Lawmakers and Governor Maura Healey are already scrambling to plug holes created by looming federal funding reductions that total in the billions for Massachusetts, according to Axios.
Those cuts are not just abstract line items. Human service providers across the state have announced layoffs and scale-backs to cope with shrinking support, as Boston.com reported earlier this month, documenting more than 200 job losses at three organizations. The AG’s suit drops straight into that budget storm.
Legal and national implications
The case taps into a broader national storyline around “upcoding,” where insurers are accused of inflating diagnoses so they can bill government programs at higher rates. That practice has already produced hefty settlements and enforcement actions at the federal level, according to the U.S. Department of Justice.
Campbell’s office is asking the court to claw back what it calls improper payments and to impose treble damages and other remedies laid out in the complaint, Investing.com reports.
The AG’s team says the case will move forward in Suffolk Superior Court and that it intends to recover taxpayer dollars tied to the alleged conduct, according to Mass.gov. UnitedHealthcare has declined to elaborate beyond its statement that the claims are baseless. With billions in public health spending on the line and Medicaid oversight tightening nationwide, the showdown is likely to draw close watch from regulators and budget hawks alike.
