Patient Portal UPDATE
We are in the process of phasing out our existing patient portal NextMD and will be moving to a new patient portal platform in May 2022. You are still able login to the existing Next MD portal to use features like medication refills, secure messages to your provider, appointment list, and your personal health record from MOS.
For help with the patient portal
(This is a third party site and MOS staff will not be able to assist you.)
Please call our Patient Contact Center and request a call back. Please note that in 2021 there is a hold time on our phone lines as patients book back in after COVID. If you are on hold on our phone lines, you can leave a call back number and we will return your call as soon as we can, we promise.
