New York City-based Mount Sinai began notifying 33,730 patients Aug. 2 that their personal health information may have been exposed in a data breach at American Medical Collection Agency.
Mount Sinai Pathology Associates had contracted with AMCA for billing collection services. AMCA notified Mount Sinai June 4 that some patient information may have been exposed due to an unauthorized person who gained access to AMCA's system.
Patient data that was affected included names, dates of medical services, names of lab or medical service providers, referring physicians, health insurance information and other medical information. A limited number of patients may have also had their financial information exposed.
Mount Sinai is recommending patients review statements from their providers and their explanation of benefits from insurers.
Since the data breach, Mount Sinai has stopped doing business with AMCA and is working to secure all patient data in the billing collection company's database.
