Methodist University Data Breach Affects Patient PII & PHI

Methodist University Emergency Physicians, PLLC, an emergency medicine group based in Memphis, Tenn., experienced a cyberattack. On May 22, 2025, ApolloMD Business Services, a company providing administrative services to the medical group, discovered suspicious activity in its IT environment. An investigation determined that an unauthorized actor compromised patient files between May 22 and May 23, 2025.

Exposed information included names, dates of birth, Social Security numbers, addresses, diagnosis information, provider names, dates of service, treatment information and health insurance information. This combination of PII and PHI increases the risk of identity theft and medical fraud.

The data breach involved patients who received care from Methodist University Emergency Physicians and other medical practices affiliated with ApolloMD. The company began notifying impacted individuals on Sept. 17, 2025.

ApolloMD also published a Notice of Data Security Incident on its website. The data breach is believed to involve several thousand patients.
