Patients can now access read-only health information via the MyChart portal while calling their local clinics for full service. Scheduling and messaging features through the digital portal remain disabled as security testing continues.
The takeaway
The system is currently in a transitional state with essential physical services active and digital features partially restored. Patients should monitor the official Luminis Health portal for updates regarding the reactivation of messaging and scheduling functionality.
