Unlimited Technology Systems Data Breach Affects 3.8 Million Patients
Unlimited Technology Systems, an Ohio-based revenue cycle management company serving healthcare providers, suffered a data breach in October 2025 that exposed information belonging to approximately 3.8 million patients. The breach was discovered days after it occurred and publicly reported months later.
Why this matters: Revenue cycle management companies sit in the middle of healthcare billing. They touch patient names, insurance details, diagnoses, and financial records for millions of people who never chose to share data with them directly. When they get breached, patients have no idea their information was even there. 3.8 million people is not a rounding error. The gap between when this breach happened and when it became public news is also worth paying attention to — that is a long time to be exposed without knowing it.
