What happened?
The letter puts the intrusion on Genesis's network, not the center's own. The investigation found that certain files on that network, which holds some of the center's data, were accessed without authorization. The center then reviewed those files to see what they held and whom they concerned.
| Date | What the letter and the regulators' records say |
|---|---|
| April 16, 2026 | Date of breach on the California record |
| June 22, 2026 | Genesis finds unusual activity on its network |
| August 19, 2026 | Letter date |
| August 21, 2026 | Report to HHS (51,352); notice recorded by California |
| August 29, 2026 | Logged in Massachusetts (6 residents) |
The California record dates the breach to April 16, about ten weeks before Genesis found the activity; the letter itself gives no start date. The center's HHS report marks "No" in the column for a business associate, although the letter places the incident at the management company.
What information was involved?
The letter lists the reader's name together with one or more of these, where the center held them: Social Security number, driver's license or other government ID number, date of birth, diagnosis and treatment information, prescription information, provider name and location, dates of service, medical record number, patient account number, Medicare or Medicaid ID number, lab results and health insurance information. Massachusetts' record for its six residents marks Social Security numbers, medical records and driver's licenses as breached.
What did Genesis and the center do?
The letter says Genesis worked with specialists on the investigation, added security measures, notified law enforcement and is reviewing its data protection policies. It also says Genesis took steps to make sure the data was re-secured and not distributed, and that the center knows of no fraud or publication resulting from the incident. The letter does not say what those steps were.
What is the center offering?

California's breach-notice rule
California's breach law (Civil Code § 1798.82 for businesses, § 1798.29 for state agencies) requires any person or business that must notify more than 500 California residents of a single breach to submit one sample copy of that notice to the Attorney General electronically. The California Attorney General's breach list, where this notice was found, is built from those submissions. Source: California Department of Justice, Office of the Attorney General, Data Security Breach Reporting. The guide Data breach laws by state: notice deadlines and attorney general thresholds in 23 states reads the rule in full, and the glossary defines Breach notification law.
