Radia Data Breach: Lawsuit Investigation

Attorneys working with ClassAction.org are looking into whether a class action lawsuit can be filed in light of the Radia data breach.

As part of their investigation, they need to hear from individuals who had their information exposed in the incident, including those who received notice of the Radia data breach or otherwise believe they are affected.

Radia Security Incident: What Happened?

Radia, a Washington-based radiology group that serves over 50 hospitals and clinics in Washington and Idaho, has reported a data breach that may have exposed sensitive patient information.

According to a notice posted to its website, Radia first learned of a data security incident on July 8, 2026. Following an investigation with a third-party forensic firm, Radia determined that an unauthorized party accessed and acquired certain files. On July 20 of this year, the healthcare group concluded that these files contained patient information.

Information that may have been compromised in the Radia data breach includes patient names, addresses, dates of birth, dates of service, provider names, treatment information (including diagnoses and conditions), medical record numbers, patient account numbers, medical billing account numbers, Medicare identification numbers and health insurance information.

Radia's review of the impacted data is ongoing, and the practice began notifying potentially affected individuals by mail on September 18, 2026.

Prior to the official disclosure, ransomware group Chaos claimed to be responsible for an attack that supposedly involved access to the radiology group's internal network and sensitive data infrastructure, per a July 16, 2026 post on cybersecurity monitoring platform DeXpose.

What You Can Do After the Radia Data Breach

If your information was exposed in the Radia data breach, attorneys want to hear from you. You may be able to start a class action lawsuit to recover compensation for loss of privacy, lost time, out-of-pocket costs, and more.

A successful case could also force Radia to ensure they take proper steps to protect the information they were entrusted with.
