Add a feature on the BC Billing page when creating an invoice to list the doctor who has been already added to the patient's master record as the referral doctor. Also list the recently used referral doctor's on the invoice similar to how the last 3 diagnostic codes list on the same page. Since often the same referral doctors are used this will help to not have to search the billingreferral table and save some clicks.
BC Billing Create Invoice Page
No risks if not incorporated but this would help to simplify populating the two referral doctor fields on the BC Billing page.
Test that the referral doctor fields are populated when clicked
Minimum if any since users are already use to populate the fields via the code search button and the feature reacts similar to the diagnostic code feature on the same page.
