The EDI System is accessible 24 hours a day, 7 days a week. EDI files submitted after the end of daytime indicated on any business day are not considered "received" until the next business day. EDI files submitted on a non-business day are not considered "received" until the next business day or as published. Claim file response reports may be delayed during these time periods, and for several hours after, as our system cycles complete.
The system also allows for multiple transmissions within one day, simply by assigning a unique submission number to each transmission. Your vendor/programmer can explain how this is done.
