The billing company discovered the data breach in March. Austin Pathology Associates was notified in May about the incident and conducted its own investigation.
At first, AMCA sent letters to around 1,800 Austin Pathology Associates patients. However, Austin Pathology Associates estimates another 44,700 patients may have been affected by the breach.
Patient information that may have been exposed included names, addresses, phone numbers, dates of birth, dates of service, balance information, credit card or banking information and treatment provider information. No Social Security numbers were affected.
Since the incident, Austin Pathology Associates has ended its relationship with AMCA.
