Firstsource Health Plans Data Breach Exposes Social Security Numbers Due to Programming Error
Shamis & Gentile P.A., a class action law firm specializing in data breach cases, is investigating a security incident involving Firstsource Health Plans and Healthcare Services, LLC, a U.S.-based provider of business process outsourcing and digital services for healthcare organizations.
The company, which serves health plans and payer operations with services like claims processing, billing, and member enrollment, recently identified a programming error in its platform. The flaw potentially allowed unauthorized access to sensitive personal information uploaded by clients, including documents related to healthcare claims and correspondence.
Firstsource reported the breach to the Massachusetts Attorney General on July 15, 2026, confirming that Social Security numbers were the only type of exposed data identified so far. The incident affects individuals whose information was processed through the company’s client engagements and health benefit plans.
Legal teams are now reviewing potential claims for compensation on behalf of affected individuals. The investigation remains ongoing.
