McKenzie Memorial Hospital—also known as McKenzie Health System in Sanilac County, Michigan—confirmed that an unauthorized party infiltrated its network between April 14 and April 15, 2025. The hospital publicly disclosed the incident on June 13, 2025, alerting patients and employees that both personally identifiable information (PII) and protected health information (PHI) were compromised.
What Happened?
- April 15, 2025: Suspicious network activity detected.
- Investigation results: Unidentified actor accessed files for roughly 24 hours (April 14–15).
- June 13, 2025: Hospital posted a “Notification of Data Security Incident” and began mailing letters to affected individuals.
- Current status: Ongoing forensic review, law-enforcement notification, dedicated call center (844-536-8079) for patient inquiries.
What Information Was Exposed?
The investigation indicates that the attacker may have accessed the following data:
- Full name, postal address, phone number, and email address
- Social Security number
- Driver’s license or state ID number
- Date of birth
- Medical diagnosis and treatment details
- Date of service, patient account and medical record numbers
- Health-insurance claim and policy numbers
- Employee bank-account numbers
- Treatment cost or billing information
Who Is Affected?
Anyone who received care, insurance billing, or employment compensation through McKenzie Memorial Hospital prior to April 15, 2025, could be impacted. Notice letters are being mailed in phases, so even if you haven’t received a letter yet, your data may still be at risk.
Your Legal Options
Healthcare providers have a legal duty to secure patient information. When that duty is breached, victims may pursue compensation for:
- Out-of-pocket expenses (credit monitoring, account fees, etc.)
- Time spent resolving fraud or medical identity theft
- Potential future losses related to misuse of exposed data
- Emotional distress caused by the breach
Filing a data-breach claim costs nothing up front. Attorneys typically work on contingency, meaning they are paid only if the case succeeds.
