the procedures and amounts due is sent. For pharmacies, an invoice listing the drugs supplied and amounts due is sent.
For nurses visiting individuals at home, an invoice listing home nursing care services and amounts due is sent. One
invoice for each patient and individual healthcare institution is prepared every month. Invoices contain information about
the reasons that individuals received medical care, the cost of the care and other items. JAST converts this information
