Free Medisoft Tech Help- Medisoft V26, Medisoft Clinical EHR & More- Courtesy Support Resource

I am using Medisoft v24 and InterfaceEDI v5. I am receiving the below error. I have tried putting the Payer Control Number in Case > Medicaid and Tricare tab, Original Reference field, as suggested in two other posts; however, it is not populated on the 837 data file. I have tried adding a 1 to the Resubmission Number field. Any help with what I'm missing would be greatly appreciated.

BCBS TEXAS PSE|R|C371P|Payer Claim Control Number (loop 2300, REF*F8) must contain at least 13 alphanumeric characters.|2300|REF|2||||5010A1|

You'll have to check with the maker of InterfaceEDI since their software may not be programmed the same way as Revenue Management that is built into Medisoft.
