Compumedics Data Breach Investigation

Written by Joseph Lyon on . Posted in Data Breach.

The data breach lawyers at The Lyon Firm are investigating a recent data breach incident involving Compumedics USA Inc., a provider of sleep disorder diagnostic technologies for sleep study clinics. The company recently disclosed a data security breach that has allegedly compromised the personal and medical information of patients across multiple healthcare providers.

If you’ve used services from clinics like Bermuda Sleep & Signature Services, Hope Healthcare, or Northern Light Health, your sensitive data may be at risk. Our attorneys are reviewing cases and representing affected individuals in a potential class action lawsuit to seek accountability and compensation.

What Happened at Compumedics?

On March 22, 2025, Compumedics detected unauthorized access to its network, disrupting its IT systems. An investigation, joined by by third-party forensics experts, confirmed that between February 15, 2025, and March 23, 2025, an unauthorized party accessed and copied internal files. The breach was reportedly fully assessed by May 13, 2025, revealing that patient data—including names, dates of birth, medical record numbers, diagnoses, treatment details, and sleep study results—had been stolen. For some, Social Security numbers were also exposed, amplifying the threat of identity theft.

This breach affects patients of healthcare providers like Bronson Healthcare Group, Billings Clinic, and VCU Health System Authority, among others. The stolen data may lead to financial fraud, identity theft, and emotional distress. Data breach notification letters were sent to impacted individuals around June 27, 2025, but the full scope of affected individuals remains unclear as the incident hasn’t yet appeared on the HHS OCR breach portal.

Compumedics said the following healthcare provider clients have been affected by the incident:

  • Bermuda Sleep & Signature Services
  • Hope Healthcare
  • Bronson Healthcare Group
  • Chest Medicine Associates PA
  • Billings Clinic
  • Davis Medical Center
  • Northern Light AR Gould
