"Unallocated" means that patient(s) have pre-paid for treatment that has not yet been charged as completed. An unallocated payment is a payment that exceeds the current patient amount due. As a result of the pre-payment, the payment is held in in the unallocated portion until a procedure is completed that needs a portion of the pre-payment. Denticon does not allocate payment amounts until a procedure has been completed that needs a patient payment.
