Not finding your patient?

If your patient’s group ID number is made up of 8 characters (e.g. GRV12345) then you will want to visit PreferredOne’s provider portal for that patient. 

In 2023, Gravie began to process the majority of our claims in-house instead of with PreferredOne. However, we still have a few plans with claims being processed by PreferredOne.
