All updates to FROIs filed on paper prior to EDI reporting should be reported on paper. Claims reported to LWC on paper prior to trading partners' EDI implementation date, should be concluded using the LWC paper forms. Going forward from the implementation date for reporting EDI, the FROI reports should be sent electronically. However, the LWC-WC-1002 and LWC-WC-1003 forms should continue to be sent to LWC.

A legacy claim is a claim that was established prior to LWC’s EDI implementation date.    

If a trading partner changes any aspect of their approved process or system, then the
trading partner must repeat the test process with LWC. LWC recommends that the
trading partner continue with the approved production process while testing any new
process, software or system. Considerations on the testing that will be required will be
determined based on the situation. Any change in the manner by which data enters the
reporting stream must be brought to our attention, and will probably involve discussion,
testing and updates made to the Trading Partner Profile. If this situation arises, please
contact the LWC EDI Coordinator ( immediately. 

Immediately after a trading partner becomes aware that data/claims are not being sent or received by LWC, you must be prepared to submit all back log data immediately once your systems are fully functioning. Immediately contact the LWC EDI Coordinator at right away. Otherwise, your organization may be subject to penalties for failure or late reporting.

LWC recommends that the Claim Administrator develop or obtain tools to use the
acknowledgment details to track overall performance. 

The acknowledgements are scheduled to be returned within 48 hours. Refer to the
Implementation Information page located at for more details. 

All questions should be directed to the LWC EDI Support Mailbox at

It is LWC’s goal to begin testing and moving our trading partners into production as
quickly as possible. After the testing process has been completed, which is described in
the “LWC - Release 3.0 Implementation Test Plan” under LWC EDI Resources
(, each trading partner will be assigned a production date. 

Please refer to the “Registration Instructions” link under the Trading Partner Profile
section ( All certified vendors should send an email to requesting to become a vendor. Upon LWC’s receipt of this request,
an internal approval process will be conducted. All certified vendors who become
approved reporters or senders of information to LWC must also complete and pass the
necessary testing procedures.

EDI has been around for over thirty years now and is regarded as a very mature IT
technology. As EDI is so entrenched within many companies it is very difficult to replace
with another technology overnight. As new technology, such as the Internet, has
emerged, EDI has had to embrace these new technologies to remain an efficient business
tool for communicating documents between companies. 

The EDI system is open seven days a week, virtually 24 hours a day.    

EDI can be implemented almost immediately, depending on the type of EDI solution
chosen. There are three ways to implement EDI: LWC Web Entry, EDI vendor, Secure
file transfer protocol (SFTP). If it is a web-based solution hosted by your customer or
client, then all you will need to do is log into the web portal and simply fill in the
necessary online forms before sending the required documents. More complex systems
will require software to be installed on your company’s network that will then allow
integration with your back-office systems. 

Current EDI users indicate they save the time it normally takes to complete the form on paper. In addition to your time, there are savings of paper and postage. Louisiana legislature passed laws requiring insurers, self administrators including state, parish, municipalities and school boards to file accident reports with the LWC in an electronic format compatible with national EDI standards.

An EDI trading partner is simply another company that you exchange documents with. 

EDI is used in nearly all the major industries such as insurance, automotive, retail, and
finance sectors. EDI is regarded as the standard for the electronic exchange of documents
from one company to another. 

Electronic Data Interchange is the exchange of business documents such as first reports of injury (FROI) and subsequent reports of injury (SROI) forms, between trading partners in a common format directly from one computer to another.

Consider the volume before deciding on your method of submission:  SFTP (Secure File Transfer Protocol) is the most technical and means you will develop the programs and IAIABC claims release 3.0 flat file content yourself, EDI Vendor means a company will provide you with EDI services, LWC Web Entry is used for low volume and means you will type the data in form by form.

Refer to LWC Element Requirement table and Event Table, which communicates the MTCs as listed below.

00 = Original Report
01 = Cancellation
02 = Change
04 = Denial
AQ = Acquired Claim
AU = Acquired Unallocated

No.  Louisiana does not send "transaction accepted with errors" (TEs)

Insured Report Number is a number that is assigned by the Insured or the Web Entry User to be used in identification of the claim. Whoever is creating the report can decide what number to use in that field, but typically our customers use the same number as the Claim Admin Claim Number (DN 0015) to make it easier.
