Data incidents have recently been announced by ProxyCare in Florida, Oscar Health in New York, and AccentCare in Texas.
ProxyCare, Florida
ProxyCare LLC, a Sunrise, Florida-based provider of personalized pharmacy services, has started mailing notification letters to individuals impacted by an August 2025 cybersecurity incident. The company learned on August 22, 2025, that certain computer systems within its network environment had been affected by a cybersecurity incident. Third-party cybersecurity professionals were engaged to determine the nature and scope of the incident, and whether, and to what extent, patient information had been compromised.
The investigation confirmed that patient data had been exposed, and following a comprehensive manual document review, ProxyCare determined on January 29, 2026, that files accessed or acquired by an unauthorized third party in the incident included names, dates of birth, Social Security numbers, and driver’s license numbers. Notification letters were mailed to the affected individuals on March 23, 2026, and individuals whose Social Security numbers were involved have been offered complimentary credit monitoring and identity theft protection services.
Based on notifications to state attorneys general, around 150 individuals in Massachusetts and New Hampshire have been affected, but it is currently unclear how many individuals have been affected in total, as the incident has yet to be added to the HHS’ Office for Civil Rights breach portal.
Oscar Health, New York
Oscar Health, Inc., a New York-based health insurance company, has recently disclosed a data privacy incident that resulted in the unauthorized disclosure of a limited amount of member information. On December 31, 2025, Oscar Health learned that member identification cards and other enrollment information related to 2026 health insurance coverage were inadvertently mailed to old and potentially incorrect member addresses.
When the error was identified, immediate action was taken to prevent similar mis-mailing incidents, and an investigation was launched to determine the scope of the event. All individuals potentially affected were identified, and notification letters have now been sent to individuals for whom correct address information could be found, warning them that their name, health insurance policy number, and health insurance plan information were potentially impermissibly disclosed.
Oscar Health confirmed that highly sensitive information such as Social Security numbers, government identification numbers, and financial information was not involved, and there has been no known misuse of the disclosed information. The data breach notice was issued individually and on behalf of its affiliated covered entities, including Oscar Health Plan, Inc., Oscar Insurance Company of Florida, and Oscar Health Plan of Georgia. The incident affected up to 91,350 individuals.
AccentCare, Texas
AccentCare, a Texas-based provider of home health, palliative, and hospice services, has been affected by a data breach at its billing service vendor, Doctor Alliance. The protected health information of 19,772 individuals was potentially compromised in the incident. Doctor Alliance determined on November 16, 2025, that an unauthorized third party had accessed a web application. The forensic investigation determined that the threat actor had access to the application between October 31, 2025, and November 16, 2025, and accessed or exfiltrated files containing patient information.
Data compromised in the incident included names, Social Security numbers, medical record numbers, Medicare numbers, diagnosis/treatment information, provider information, and medical/health information. AccentCare said there was no unauthorized access to its own systems, and no impact to the care provided to its patients. AccentCare is monitoring Doctor Alliance’s response to the incident and its continued role as a service provider.
