Payer entering arrangement with Financial custodian for HDHP (HSA). Financial custodian will issue credit card. Member will use credit card at point of service. Agreement is for payer to send claims liability and cost share data to the Financial custodian, who will then match to their credit card authorization file, and if matched, provide settlement to the merchant (provider). Match process can result in full match, no match or soft match. Potential for better match processing and better experience if we can identify a mechanism for provider to enter the credit card autghorization number and "swipe" date on the 837's. Currently no field available to provide these data elements. More background available on request.
