About This Breach
Zumpano Patricios represents healthcare providers in disputes concerning insurance payments. As a result, the incident also involved some patient information that healthcare organizations had provided to the firm.
How did the Zumpano Patricios data breach happen?
The firm detected the attack on or about May 6, 2025 and blocked the unauthorized access. Its investigation found that the attacker may have had an opportunity to access and remove copies of certain files.
The firm did not identify when the intrusion began. May 6 is therefore the detection date, not a claimed start date for the attack.
What information may have been affected?
The categories varied by person. The firm said affected files may have contained names, provider names, member identification numbers, health-insurer information, dates of service, and details about amounts charged and payments received.
Social Security numbers, clinical coding information, or medical records may also have been involved for some people. Not every category applied to every individual, and medical records held in healthcare providers' own systems were not affected by this incident.
How many people were affected?
The current HHS Office for Civil Rights record reports 279,275 affected individuals. This is the published affected-person total for the incident.
What risks can this information create?
Identity and health information can make targeted fraud and identity-theft attempts more convincing. An unexpected message that cites a member number, service date, or payment detail should still be verified through an independent official channel.
People whose Social Security numbers were involved may also face fraudulent account or credit applications. Medical records and clinical codes can create lasting privacy risks.
How did the firm respond?
Zumpano Patricios said it changed passwords, blocked unauthorized access, and engaged outside experts to investigate the scope. Potentially affected individuals were notified, and eligible recipients were offered credit monitoring and identity-theft protection.
What should affected people do?
Notice recipients can monitor credit reports, financial accounts, health-insurance statements, and medical bills for unfamiliar activity. If a Social Security number was involved, a credit freeze or fraud alert may be appropriate.
Emails or calls claiming to concern the incident should be verified through the firm's official website or a previously known contact number rather than through links or contact details supplied in the message.
