On August 3, 2021, a physical break-in occurred at the Foundation for Medical Care of Merced County's facility. An unknown intruder entered by punching a hole through a wall from an adjacent office suite and stole an external backup drive containing scanned paper medical and dental claims. Data potentially exposed included names, healthcare ID numbers, addresses, dates of birth, provider names, procedure/diagnosis codes, and claim charges (PHI). The Foundation notified Merced Police, added building security, and offered one year of Experian IdentityWorks to affected individuals.
