About This Breach
The investigation found that certain files may have been accessed or removed that day, and the possible data scope was determined on 13 March.
The U.S. Department of Health and Human Services Office for Civil Rights (HHS/OCR) lists the event as a hacking or IT incident involving a network server and reports 10,216 affected people. This is a person count, not a count of accessed files or individual data fields.
What information may have been involved?
The official notice lists names, dates of birth, Social security numbers, patient numbers, and dates of service. Health insurance and health-plan beneficiary information, medical treatment information, and medical diagnostic information may also have been involved. The notice says files may have been accessed or removed; it does not establish that every data category applied to all 10,216 people or that every listed field was definitely taken. Passwords, payment-card data, and bank-account information are not among the disclosed categories.
Organization response and safe next steps
Bayside Dental said it secured the network and investigated with external cybersecurity specialists. At the time of the official notice, the practice had no evidence that personal information had been used for financial fraud or identity theft. Notice recipients should use their individual letter as the primary source for their data scope and protection options. Credit reports and health insurance statements can be reviewed for unfamiliar accounts, claims, or services. Unexpected messages claiming to represent the practice should be verified through a current official contact channel without using links in the message.
