AltaMed December 2025 Data Breach — Class Action Investigation Active Through April 2026
AltaMed (largest U.S. FQHC, 3,500+ staff, 600K+ patients) experienced a cybersecurity incident on December 14, 2025; class action investigation actively soliciting plaintiffs through April. Could affect patient trust and operational costs.
Cybersecurity exposure for the country's largest FQHC has implications for HIPAA compliance posture across all CA FQHCs — peer FQHCs should review incident response plans, third-party vendor cybersecurity, and PHI handling protocols. Compounds with MMG Fusion 15M-individual dental software breach already in feed.
AltaMed has not publicly disclosed scope of affected records.
