Sum total of all medical item amounts.
This property is required when submitting a Healthcare Auto-substantiation transaction, and should indicate the sum total of all VisionAmounts, PrescriptionAmounts, ClinicAmounts, and DentalAmounts, plus any additional healthcare-related charges that do not fall under those categories. The category-specific amounts are optional, but at the minimum the TotalMedicalAmount must be present for Healthcare auto-substantiation.
If other amounts are present, the TotalMedicalAmount must be greater than or equal to the total of all other amounts. If the TotalMedicalAmount is left blank, the transaction will be sent as a regular Retail transaction, without the healthcare indicator. If you wish to send a transaction with the healthcare indicator, but no TotalMedicalAmount, set TotalMedicalAmount to "0".
If the transaction is only for healthcare related costs, the TotalMedicalAmount should be equal to the TransactionAmount. However, it is possible to authorize a transaction that includes non-healthcare items, where the TransactionAmount is higher than the TotalMedicalAmount. It may be required that you set PartialAuthorization to True in order to support this functionality.
This must be presented with an implied decimal point. For example, US $10.00 must be represented as 1000, and $0.10 is likewise simply 10.
