Did the RXNT breach affect members of Congress?
Yes. The HIPAA Journal reported on May 15, 2026 that the Office of the Attending Physician, which manages care for members of Congress, uses RXNT's software to send prescriptions to pharmacies, and that some of that prescription information was stolen. The items it listed for those patients are names, addresses, dates of birth, physician names, and prescription and pharmacy information. It reported that the members' medical records, Social Security numbers and financial information were not involved, because only what a prescription needs goes into the software.
The office had not said how many members or staff were affected, the same report said. The 353,844 on the HHS portal is RXNT's figure for all of its customers' patients, not a count for Congress.
Why did patients hear about RXNT months after the attack?
Because RXNT is a business associate: it told the practices that use its software first, and the practices then had to notify their patients. RXNT began notifying its customers on May 1, 2026, about two months after it found the activity on March 3. The HIPAA Journal explained that under the HIPAA Breach Notification Rule a business associate has 60 days to tell its covered-entity clients, and each client then has 60 days to notify individuals, though it can hand that task to the business associate. The HIPAA Breach Notification Rule entry explains the deadlines.
What happened in the RXNT data breach?
RXNT says it became aware on March 3, 2026 of unauthorized activity in one of its software products used by some of its customers, investigated with cybersecurity experts, removed the intruder and notified law enforcement. It began notifying affected customers, the healthcare providers, on May 1, 2026.

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.
