A suspected cyber incident left Parkview Health patients without MyChart and online doctor searches Monday after the Indiana-based health system disabled its network in response to suspicious activity.
Parkview said it proactively disabled the network in response to “suspicious activity,” 21Alive News reported.
Patients with urgent medical needs were directed to call their provider’s office or visit a walk-in clinic. Parkview’s website notice told people experiencing a medical emergency to call 911.

“We are working to restore services as quickly and safely as possible,” a Parkview spokesperson told the station.
Patients normally use MyChart to check test results, exchange messages with clinicians, request prescription refills and schedule or cancel appointments.
Parkview’s website described an internet outage affecting multiple systems, but did not name other affected services.
The Fort Wayne-based nonprofit serves Indiana and northwest Ohio through 16 hospitals and more than 300 outpatient centers and physician offices.
Parkview told 21Alive there was “no indication” that data had been compromised. It has not explained the suspicious activity or detailed any effects on appointments and care at individual facilities.
A September cybersecurity incident at Luminis Health in Maryland also disrupted MyChart and other online patient services. Luminis said outpatient appointments would proceed unless patients were contacted directly.
Parkview was still working to restore access Monday afternoon and had not announced when services would return.
