Lake Washington Vascular Data Breach

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

As part of their investigation, they need to hear from individuals who received a notice stating they were impacted.

On February 14, 2025, Lake Washington Vascular experienced a data breach when an intruder accessed its network and installed malware. According to a press release on the healthcare provider's website, the malware encrypted the practice's electronic medical record and practice management systems. 

Lake Washington Vascular noted that the compromised systems contain personal and health information of about 30,000 patients, including names, birth dates, addresses, government-issued IDs, diagnostic test results, medical histories, and treatment details, though it has not been determined exactly what information may have been taken or viewed by the unauthorized party. Financial information like credit card and banking details are not stored in these systems, the practice wrote.

The Lake Washington Vascular data breach impacted 21,534 people, according to a report provided to the U.S. Department of Health and Human Services.

Lake Washington Vascular has offices in Bellevue and Kirkland, Washington.

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

A successful case could also force Lake Washington Vascular to ensure it takes proper steps to protect the information it was entrusted with.
