Jeffrey Lisiecki, MD, PLLC’s Data Breach Investigation

Jeffrey Lisiecki, MD, PLLC recently disclosed a data privacy incident involving unauthorized access to an employee email account containing sensitive patient information. According to the notification letter sent to affected individuals, the medical practice learned of a potential email security incident and immediately engaged outside cybersecurity professionals to investigate the matter.

The investigation determined that a single employee email account had been accessed by an unauthorized party sometime between November 2024 and January 2026. Following a review of the contents of the compromised account, the organization determined on April 19, 2026, that protected health information (“PHI”) belonging to patients was present within the account.

According to the notice, the information potentially exposed during the incident included patients’ first and last names in combination with scheduling information and additional data shared with the medical office. The compromised information reportedly included dates of birth, medical health records, and photographs.

Healthcare-related data breaches are particularly concerning because medical information is highly sensitive and difficult to replace once exposed. Unlike financial information such as credit card numbers, medical records and health-related identifiers can create long-term privacy risks for affected individuals. Cybercriminals may target healthcare information for identity theft, fraudulent insurance claims, phishing attacks, or other forms of misuse.

Jeffrey Lisiecki, MD, PLLC stated that it secured the compromised email account and reported the incident to the U.S. Department of Health and Human Services Office for Civil Rights. The organization also advised affected individuals to remain vigilant for signs of fraud or suspicious activity involving their accounts and personal information.

Although the practice stated that it had no evidence indicating misuse of the information for fraud or identity theft at the time notices were sent, data privacy incidents involving medical records can still create ongoing concerns for affected individuals. Exposed health information may contain deeply personal details that consumers expect healthcare providers to safeguard carefully.

The incident highlights the growing cybersecurity risks facing healthcare providers and medical offices nationwide. Email account compromises remain one of the most common causes of healthcare data breaches because employee email accounts often contain patient communications, records, scheduling information, insurance details, and other protected information.

Organizations that collect and store sensitive health information are generally expected to implement reasonable safeguards designed to protect patient data from unauthorized access. Healthcare providers may face increased legal scrutiny when breaches expose protected health information or reveal weaknesses in cybersecurity practices.

The notification letter encouraged affected individuals to review account statements, monitor credit reports, and watch for suspicious activity. Consumers impacted by data breaches involving medical information are often advised to remain cautious of phishing emails or scam communications referencing the incident.

As healthcare data breaches continue to rise across the country, many affected individuals are exploring their legal rights and whether compensation may be available for privacy violations, emotional distress, identity theft risks, and other damages associated with the exposure of sensitive health information.

What You Can Do

First, monitor your financial accounts, medical insurance statements, and credit reports for suspicious or unauthorized activity. Unfamiliar charges, insurance claims, or medical services could indicate potential misuse of your information.

You may also wish to place a fraud alert or security freeze on your credit reports through Equifax, Experian, and TransUnion. Fraud alerts encourage lenders to verify your identity before issuing credit, while security freezes can help restrict access to your credit file.

Medical identity theft can sometimes involve fraudulent insurance claims or unauthorized medical treatment billed in another person’s name.

Many people impacted by healthcare data breaches may not realize they have legal rights. Learning more about your legal options may help you understand whether compensation could be available for privacy violations, identity theft risks, emotional distress, or time spent responding to the breach.
