Occasionally you will receive claims back from the health fund with exceptions relating to different paid and claimed amounts. If the claimed and paid amounts are significantly different, and you are wanting to apply to the health fund for a top up simply ignore the exceptions and receipt what has been paid from the Exceptions to Review window. This will cause the claim to move to Part Paid. You can then print this invoice off from the patient's Account History and send this to the fund for a top up.
Once the fund has paid the remaining amount, you can simply receipt the payment via invoice number (Billing> Receipt by Invoice Number). This will then move the claim to Finalised.
If the health fund will not pay the remaining amount, you can readdress the invoice to the patient and request that they pay what is outstanding. When the patient pays, the payment can be receipted by invoice number.
If the patient won't pay or you don't wish to charge them, you can simply apply a credit to the invoice so that the outstanding amount is written off.
