Luminis Health

Profile narrative

Luminis Health is a health system that operates medical facilities primarily in central Maryland and on the Eastern Shore of the United States. It provides a range of healthcare services to patients in those regions, including inpatient and outpatient care. The organization offers an online patient portal, known as MyChart, which allows patients to access their health information, schedule appointments, and communicate with providers. The health system emphasizes delivering safe, high-quality care to its community.

In August 2021, Luminis Health experienced a cybersecurity incident involving its email server that resulted in the exposure of patient personal information. More recently, on September 2, 2026, the organization announced a cyberattack that disrupted certain systems, notably taking the MyChart patient portal offline shortly after the announcement. Despite these disruptions, Luminis Health stated that its priority remains providing safe, high-quality care and expressed appreciation for the community's patience and understanding.

The health system's headquarters is located in the United States of America, though the exact city is not specified in the available sources. Luminis Health functions as an integrated delivery network, coordinating care across its facilities to serve the populations of central Maryland and the Eastern Shore. No further details about its size, ownership structure, or subsidiaries are provided in the source material.
