First, check which authorization is used to create the claim. If it is Inactive, then change the status to Active. Alternatively, you can create a new authorization with the preferred insurance company and save changes. 

To resolve this issue, please follow the steps below:

1. Update the insurance under the patient's authorization in the Patients' Profile.  
2. Navigate to Billing > Primary Billing Manager. 
3. Go to the 1st tab: Process Billing. 
4. Select the preferred claim using the checkboxes. 
5. Retract the claim using the dropdown above the list. 
6. Generate the claim again.

This should allow the claim to be billed to the right insurance company.
