To add a New Insurance Company you need to either have the correct permission level, such as Administrator, or you need to contact the appropriate person. If you search the Resident Insurance list and the correct Insurance Company can not be found please go to the main navigation bar and select 'Insurance' under Administration.

Here you add the Insurance Company for your facility. You only need to add the new Insurance once and it will come up in future in all locations searches.
You can now return to Resident Insurance search be able to find the Insurance and add it to your residents list.
