Luminis Health confirmed this week that a cybersecurity incident has disrupted certain systems across its network, temporarily affecting services at its hospitals and more than 100 outpatient and specialty care locations.
Immediate impact and response
The health system, which operates Anne Arundel Medical Center in Annapolis and Doctors Community Medical Center in Lanham, told patients Monday that its online patient portals MyChart and CareConnectNow were unavailable and warned of potential delays. The organization said outpatient appointments would continue unless patients were contacted directly.
By Tuesday the disruption was publicly identified as a cybersecurity incident. Luminis Health said it engaged legal counsel and third-party cybersecurity experts and launched an investigation into the event. The organization has not disclosed the nature of the incident, whether patient or employee data were accessed or when affected systems will be fully restored.
"Luminis Health is currently responding to a cybersecurity incident affecting certain systems across our organization," the health system said in a statement. "Upon identifying the incident, we took immediate steps to address the situation and launched an investigation with the support of legal counsel and third-party cybersecurity experts."
Where services are affected
Officials said hospitals remain open and that providing patient care is the organization’s top priority. Some systems, however, remain unavailable as the investigation and recovery efforts continue.
Patients with questions about upcoming appointments or scheduled services were given a contact number: 443-222-0193 (during business hours).
- Systems reported unavailable: MyChart, CareConnectNow and other unspecified systems.
- Facilities served: Hospitals in Annapolis and Lanham and more than 100 outpatient and specialty locations.
- Population served: Approximately 1.8 million people in the region.
Scale and context
Luminis Health’s network covers a large portion of the state’s population through hospital and outpatient services. Disruptions to electronic health records, scheduling systems and patient portals can slow admissions, discharge processing, laboratory result distribution and appointment management, even when in-person care continues.
Healthcare organizations nationwide have faced a rising number of cybersecurity threats in recent years, prompting many systems to maintain pandemic-era contingency plans and to work regularly with outside cybersecurity firms. Luminis Health has not said whether it will notify patients about potential data exposure, a step other systems often take when investigations reveal unauthorized access to medical or personal information.
What patients should do now
Patients who have appointments should await direct communication from Luminis Health. If you have not been contacted and have concerns about your appointment or care, call the health system at 443-222-0193 during business hours.
If you received care during the period of the disruption and later notice unusual bills, missing test results or suspect unauthorized activity related to your health records, document the issue and contact the health system’s patient support line for guidance.
What officials have not disclosed
The health system has not provided details about the specific systems affected beyond its patient portals, has not stated whether the incident involves ransomware or any other malware, and has not said if protected health information was accessed. The investigation is ongoing and Luminis Health said it will provide additional updates as appropriate.
