AltaMed Data Breach Lawsuit Investigation

Were you treated by AltaMed and just learned your Social Security number or medical records were hacked? The August 2024 cyber-attack on AltaMed Health Services Corporation puts thousands at risk of identity theft and medical fraud. Find out how to protect yourself and see if you can file a claim now.

What Happened?

According to a filing with the California Attorney General, unauthorized parties infiltrated AltaMed’s systems between August 5 – August 9, 2024. The breach was confirmed and publicly disclosed on June 13, 2025, suggesting the attackers may have had months to misuse stolen data before patients were warned.

Information Exposed

The incident is classified as both a Personally Identifiable Information (PII) and Protected Health Information (PHI) breach. Data potentially leaked includes:

Highly Sensitive PII

• Full names & addresses
• Social Security numbers
• Dates of birth
• Driver’s license / state ID or passport numbers
• Foreign national IDs
• Personal emails & phone numbers
• Usernames and passwords
• Mother’s maiden name & handwritten signatures

Protected Health & Financial Data

• Medical record, Medicare, or Medicaid numbers
• Medical history, diagnoses, treatment, and procedure details
• Doctor/provider names & dates of service
• Prescription and genetic information
• COVID-19 test results or vaccination status
• Health insurance policy numbers & other insurance data
• Billing details and payment information for health services

Why This Breach Is So Serious

Stolen health data carries a double black-market value compared to ordinary credit-card info. Criminals can:

• Open new credit lines in your name using SSNs and IDs
• Submit fraudulent insurance claims or obtain medical services
• Create fake prescriptions and order drugs
• Exploit medical details for targeted phishing or blackmail

The breadth of information leaked means victims could suffer both financial loss and long-term privacy violations.

If you received an AltaMed breach letter, you have legal rights under state and federal laws such as HIPAA and the California CCPA. Act quickly:

1. Save every letter or email from AltaMed.
2. Enroll in any free credit or identity monitoring the company offers.
3. Place a fraud alert or credit freeze with Equifax, Experian, and TransUnion.
4. Review medical Explanation of Benefits (EOBs) for unfamiliar services.

6. File a claim to seek compensation for time, stress, and out-of-pocket losses.
