What may have been exposed

  • Full Name
  • Date of Birth
  • Social Security Number
  • Medical Record Number
  • Health Insurance ID Number
  • Diagnosis and Treatment Information
  • Prescription Information
  • Provider and Treatment Dates

Catalyst Physician Group, a prominent healthcare provider in Texas, recently announced a data breach that may have compromised the sensitive personal and medical information of its patients. The incident, which occurred on December 2, 2025, was reported to authorities on September 15, 2026, and is currently under investigation. For those who received a notification letter, understanding the implications of this exposure is critical.

The information reportedly exposed in this breach is extensive and highly sensitive. It includes your Full Name, Date of Birth, Social Security Number, Medical Record Number, and Health Insurance ID Number. Additionally, critical health details such as Diagnosis and Treatment Information, Prescription Information, and Provider and Treatment Dates were compromised. This combination of data types poses a significant threat.

Unlike credit card numbers that can be easily replaced, this type of exposed medical and personal data is permanent and can be exploited for years. Cybercriminals can use your Social Security Number and Date of Birth for financial identity theft, fraudulent credit applications, or tax fraud. Medical identity theft is also a serious risk, where your Health Insurance ID Number or Medical Record Number could be used to obtain fraudulent medical services or prescriptions under your name.

If you have received a notification letter from Catalyst Physician Group, it is important to take immediate steps to protect yourself. Carefully review the notice for any credit monitoring or identity theft protection services offered, and consider enrolling in them. Additionally, monitor your medical statements, explanations of benefits (EOBs), and credit reports for any suspicious activity. Be wary of unsolicited communications requesting personal information.

Receiving a breach notification signifies that your private information was likely exposed due to a lapse in security. This notification grants you the legal standing to explore your options. Our team is dedicated to representing individuals affected by data breaches and offers free case reviews to help you understand your rights and potential next steps.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

  • Freeze your credit

    Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.

    Review the Explanation of Benefits statements from your health insurer for services or claims you never received, which can signal misuse of your medical identity.

  • Stay alert to targeted scams

    Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.

  • Keep your notification letter

    Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
