Firstsource Healthplans and Healthcare Services, a third-party service provider to health insurance plans, disclosed a data breach on July 15, 2026. This incident stemmed from a programming error on a document upload platform, which may have allowed unauthorized access to sensitive information. The exposed data types include names, Social Security Numbers, dates of birth, addresses, government IDs, medical information, and financial information. The total number of affected individuals has not been publicly disclosed, although the breach affects individuals nationwide whose data was handled by Firstsource through various health benefit plans. Massachusetts was explicitly noted as a state where regulatory notification occurred. Since the disclosure is recent, full impact statistics and legal proceedings may still be in the early investigation stages. Affected individuals were offered two years of complimentary credit monitoring. Details can emerge later, and notices may be delayed.
