Hi @Bo_Wang -
Yes, there is a way to create claims for all participants of a group therapy session.
The Groups module generates an encounter form for each group participant as part of documenting the group session. And claims are generated from the charges entered into the fee sheet for an encounter.
A fee sheet contains the charges for the particular encounter that is being edited at the time, so if the fee sheet menu item is greyed out that probably means you do not have an encounter form open.
One way to get to the fee sheet is to pull up the patient’s record and in their encounter list, select the group therapy encounter you want to look at (the arrow is not pointing at the Group Therapy item that was selected).
The fee sheet menu item should be active- not greyed out- in the Administration drop down menu.
Then if you pull up that patient’s encounter in the billing manager, you will see it does indeed have a claim:
