Luminis Health, which operates the Anne Arundel Medical Center in Annapolis and Doctors Community Medical Center in Lanham, said Thursday afternoon that its systems have been restored following a cyberattack at the beginning of September.
The attack took some of the company’s systems offline and temporarily caused the hospitals to divert noncritical cases from their emergency rooms.
The company continued to provide patient care during the outage, though it acknowledged that some appointments were taking longer than usual and some services remained unavailable.
“As we move forward, we remain focused on serving our communities and providing the safe, high-quality care you count on us for,” the company said on Facebook.
Luminis has been tight-lipped about the details of the attack and said it remains under investigation. It first acknowledged the cyberattack on Sept. 2.
The company said Thursday that it paused payment plans when its systems went offline, and said those plans will be reset so patients will not be penalized for the system pause.

On the company’s website, Luminis said it’s evaluating its technology and is taking “appropriate steps to further enhance our systems in light of the evolving threat landscape.”
Luminis said it continues to investigate “what information, if any,” was affected by the attack. The company said previously that the system that stores patient records was not affected.
However, MyChart, an online patient portal where people can pay bills, view test results and communicate with their doctors, was unavailable as part of the outage.
Cybersecurity experts said healthcare systems are prime targets for cybercriminals. That’s because the systems are often large and complex, healthcare systems have not traditionally invested much in cybersecurity, and because patient medical information or financial information has value on the criminal market.
