Electronic Data Interchange Rules
The 121st Maine Legislature enacted legislation that required the State of Maine Workers’ Compensation Board to adopt rules mandating electronic filing.  The legislation directed the Board to proceed by the consensus based rulemaking process.  A committee was formed consisting of representatives from the insurance community, self-insurers, WC Board of Directors, and WCB staff.  Recommendations were forwarded and unanimously approved by the Board of Directors.  The approved rules are available on the Maine Workers’ Compensation Board website.

FROI Production Deadline
As of July 1, 2005 all FROI’s must be sent to the Workers’ Compensation Board via electronic submission (EDI).  All new trading partners to the state of Maine must undergo testing in order to send FROI’s to the Maine WCB electronically.  If paper reports are received after July 1, 2005 there will be potential for a fine.  Please refer to Chapter 3, Section 4(D)(1) and Section 4(D)(2) of the Maine WCB Rules on our website at http://www.maine.gov/wcb/rules/current.html for more information.
All new insurers, self-insurers, or claim administrators that are properly licensed to write workers’ compensation policies in Maine must undergo the testing process prior to sending files in production status.  Please see the testing requirements in this document or contact that Maine Workers’ Compensation Board for more information on how to begin the testing process.
WCB Forms Required
The State of Maine WCB will focus on the electronic submission of FROI’s and SROI’s.  At this time SROI’s only consist of Full and Partial Denials.  Electronic submissions of payments forms are not currently available.  
Claims Electronic Data Reporting Format
The Maine WCB uses IAIABC Claims Release 3.0 for all claims EDI submissions.  The IAIABC Implementation Guide can be found on the Maine WCB website.  The IAIABC Implementation Guide contains helpful information such as Business and Technical Process Rules found in Section 4, Business Scenarios found in Section 5 and a Data Dictionary found in Section 6.
EDI Communication
The Maine WCB accepts two methods of communication: Approved EDI Service Providers and FTP.  Trading partners are required to indicate on their EDI Trading Partner Profile which method of communication will be used.  
FTP Procedure to the Maine WCB
1.	Complete the Vendor Profile which can be found on the WCB website under Trading Partner Documents.
2.	Secure FTP/SSL specifications
Receiver Requirements
IP Address:	mom01.secure.maine.gov
Port:		21
Server Type:	FTP over SSL (explicit encryption)
Login Name:	Please contact Paul Fortier for your login name
Password:	Please contact Paul Fortier for your password
File Naming Convention
The Maine WCB has separate file naming conventions for test files and for production files.  If you are in the testing process your input file name will be: SRdate.time; the format of the date and time is as follows: SRMMDDYYYY.HHMM   Once the file is moved from the carrier FTP site to the WCB trusted server date stamp will be added on the end of the file name by the Board to indicate when the file was received at the Board.  After the Board receives the file, the file name will look like the following: SRMMDDYYYY.HHMM.MMDDYY
Once production status has been approved, the file naming convention for a FROI Input File will be:  FRMMDDYYYY.HHMM Once the file is moved from the carrier FTP site to the WCB trusted server a date stamp will be added on the end of the file name by the Board to indicate when the file was received at the Board.  

For example, if a FROI is sent to the Board at 11:45 a.m. on July 18, 2007, then the FROI input file name will be FR07182007.1145 and once it is picked up by the WCB secure server the file name will appear as FR07182007.1145.071807 Please notice that the date on the end is in MMDDYY format and is added by the Board when the file is picked up on the WCB trusted server.
Note:	The input file name must be capitalized.
Transmission Times
The Maine WCB accepts multiple batch transmissions in one day.  Not all trading partners are equipped to send multiple transmissions and must consult with their technical team for more information.  The transmission times for multiple transmissions are 6:00 a.m., 10:00 a.m. and 2:00 p.m. Monday through Friday.  
Files that are sent to the WCB once a day will process overnight.  
Note:  The Maine WCB does not process files on Saturday, Sunday or holiday’s.  
Acknowledgement Reports:
For every batch that is sent to the WCB an AKC report confirming receipt of the batch is sent back.  The AKC report also contains information regarding each specific filing within the batch indicating whether each transaction is accepted, accepted with errors or rejected completely.
Acknowledgement reports for multiple transmission times will be available in the outbound directory no more than one hour after the transmission time.  For those who submit files once a day the acknowledgement reports will be in the outbound directory no later than 7:30 the following morning.
Note: Acknowledgement reports for batches sent Friday nights will not be available until Monday morning.
Requirements for Becoming an EDI Trading Partner
There are three requirements for becoming an EDI Trading Partner:
1.	Complete the Trading Partner Profile and Electronic Transmission Profile
2.	Complete the Trading Partner Identification List (ID List)
3.	Complete the Claim Administrator Address List
All three forms can be downloaded from the Maine WCB website.  Please complete the forms and send them via electronic mail Brad Howard.
1.	TPP and Electronic Transmission Profile
The Maine WCB requires each entity, including those who plan to use a service provider, to complete the Maine Electronic Trading Partner Profile and Transmission Profile.  The TPP provides pertinent information about the receiver, sender and transmission protocol.  
The Electronic Transmission Profile is a two part document.  The first part of the document contains information pertaining to the sender’s electronic transmission profile.  This document indicates how the trading partner will send data to the Maine WCB.  The trading partner must also provide their IP address on the transmission profile.  If an entity is sending data from more than one sending address, then a separate sender’s profile is required for each of the sender’s addresses.  
The second part of the Electronic Transmission Profile contains the WCB’s information.  This part of the form contains information needed in order to address and forward all electronic transmissions to the Maine WCB.  

2.	Trading Partner ID List
All insurers and claim administrators must fill out a Trading Partner ID List.  The form must include the master FEIN, and nine digit postal code of the sender.  The master FEIN is the FEIN of the entity that is actually sending the files to the Maine WCB.  This information must be included in the header record of every transaction.  The master FEIN and postal code information are used to identify a valid sender of EDI information to the WCB.  Once the master information is entered on the ID List, all other entities that will send claims under the master FEIN must be identified in the spaces provided.  If the master FEIN will also be sending in claims then the master FEIN and corresponding information must also be filled in the spaces provided.  The ID List must include the legal name of each entity, their FEIN and their type (i.e. Insurer, Self-Insurer and/or Claim Administrator).  One entity can be more than one type; for example and entity can be identified as both an insurer and a CA.
The ID List will be used to compile a table for each master FEIN and the entities below it for the EDI edits to run against when receiving a claim transaction.  It is extremely important to report any changes or updates to the ID List as soon as they become effective.  If changes or updates are not reported to the WCB and a claim is sent in for a FEIN that is not on the ID List the claim transaction will reject.  

3.	Claim Administrator Address List
As of May 1, 2007 the Maine WCB and IAIABC Claims Release 3 introduced the data element, DN200 CA Alternate Postal Code.   This element contains the nine digit postal code of the physical address for the claim administrator.  This is a mandatory element for the Maine WCB.  If a CA Alternate Postal Code in a transaction does not match one of the postal codes in the CA Address List, then the claim transaction will reject.  If the postal code entered in this field is a five digit number or the number is missing the claim transaction will reject.  In order for the Maine WCB to use this data element efficiently and effectively it is necessary for all trading partners to fill out a Claim Administrator Address List.  The form must include the master FEIN, legal name and postal code on the top part of the form.  In the spaces provided, please provide information for each claim administrator that is identified as such on the ID List.  It is necessary to provide the claim administrators FEIN, legal name, physical street address, city, state and nine digit postal code.  Please note that the four digit extension on the postal code relates to the physical address, not the mailing address.  
Information and Data Reported
Each piece of information for the electronic FROI and electronic SROI is defined as a data element.  Please refer to the Section 6 of the IAIABC Claims Release 3 EDI Implementation Guide for definitions of each data element.  The state of Maine does not accept all data elements on that list.  To view a complete list of data elements accepted by the Maine Workers’ Compensation Board, please refer to the Maine Element Requirement Table.  This table express the MWCB’s requirements for both business and technical data.
Transaction Type Codes Required
The transaction type code is a technical identification for all transactions sent.  Refer to Section 2 of the IAIABC Claims Release 3 Implementation Guide for a more information on each of the transaction types.  

Maintenance Type Codes 
A Maintenance Type Code (MTC) is a code that identifies the type of transaction that is sent to the WCB.  The following FROI MTC’s are accepted by the State of Maine WCB at this time:

MTC	Type of FROI	
00	Original FROI	
01	Cancel FROI	
02	Change/Update FROI	
04	Original FROI and Full Denial	
CO	Correct FROI	
AQ	Acquired FROI	
AU	Acquired/Unallocated FROI	
UR	Upon Request FROI	
Transaction Sequencing
Transaction sequencing refers to the order in which the MTC’s must be sent.  For example, a FROI 02 cannot be sent to the Maine WCB before an original FROI 00 has been sent.  For more detailed information on transaction sequencing, please see pages 4-7.1 through 4-7.6 in Section 4 Business/Technical Process Rules of the IAIABC Implementation Guide on their website.  
FROI Data Element Conditionals and Business Rules
Business rules that apply to specific data elements are also required when the data element on the table contains the second indicator of “C” or Conditional.  There are two types of conditionals, Mandatory Conditional (MC) and Expected Conditional (EC).  
FROI Mandatory Conditional Data Elements
Mandatory Conditional (MC) data elements are mandatory data fields if a specified condition exists in the transaction.  For example, the initial date of disability is a MC field.  If the Claim Type Code is “I” (indemnity/lost time) or “L” (became indemnity/lost time) then the initial date disability began (DN56) is a mandatory field.  This means that the transaction will reject if this element is not filled in.  

FROI Expected Conditional Data Elements
Expected Conditional (EC) data elements are expected data fields if a specified condition exists in the transaction.  For example, if the Insured FEIN is different than the Employer FEIN then the Insured FEIN is an expected field.  Missing an expected field or an expected conditional field will not result in a rejection, but the claim will be accepted with errors and a correction will be expected on that claim.
Default UIAN’s
There are two circumstances in which the Employer’s UIAN may not be known at the time a claim transaction is sent. Below are the two circumstances where a default UIAN may be sent:

1.	In the event that a claim needs to be sent in for a new employer and that employer has not been assigned a UIAN by the Department of Labor (DOL), a default UIAN of 0000000002 assigned by the Maine WCB may be used.  This is a default number that will tell the WCB that the employer on the claim has not yet been assigned an UIAN by the DOL.  Once an UIAN has been assigned, the insurer/claim administrator is responsible for sending in a FROI 02 to update the FROI with the correct UIAN for the employer.  The insurer/claim administrator will have 180 days from the date that the FROI is accepted in the Maine WCB’s system to send a FROI 02 with the updated information.  If the FROI 02 is not sent within 180 days, no subsequent transactions will be accepted until the Maine WCB receives and accepts the FROI 02 with the updated UIAN.

2.	Some employers are exempt from paying unemployment tax in the state of Maine, but they may still be required to provide workers’ compensation insurance.  In these cases, the state of Maine DOL will never assign a UIAN to those employers.  
In the event that a claim needs to be sent to the Maine WCB for an UI exempt employer as stated by the DOL law for exempt employment, the default UIAN that must be used in this situation is 0000000003.  This default number tells the Maine WCB that the employer is exempt from paying unemployment tax in the state of Maine and no edits will be triggered requesting the UIAN from the insurer at any time in the future.
There are several types of exempt employment types under the DOL laws.  Please visit the DOL website for more information and the laws pertaining to exempt employment.  The following link will take you directly to the DOL website.  https://www1.maine.gov/labor/unemployment/liabilityexemptions.html. 

In all other circumstances the actual UIAN issued by the DOL must be submitted with any FROI transaction.  If the UIAN is unknown to the insurer/claim administrator, it is the responsibility of that insurer/claim administrator to obtain the correct and current UIAN from the employer.  Any FROI transactions that do not have a valid UIAN will cause the transaction to reject.

Subsequent Reports of Injury
A Subsequent Report of Injury (SROI) currently consists of full and partial denials only.  Payments will be sent as subsequent reports in the future.  Please refer to our website for updates and other pertinent information regarding EDI payments.

SROI Production Deadline
As of June 1, 2006 all SROI denials must be sent to the Workers’ Compensation Board via electronic submission (EDI).   For all new insurers, self-insurers, and claim administrators please see the FROI and SROI testing requirements below and contact the Maine WCB for more information on how to start the testing process.

SROI MTC’s
MTC	DESCRIPTION	
04	Full Denial – FROI previously reported (JCN required)	
PD	Partial Denial – FROI previously reported (JCN required)	
CO	Correction to a previously filed 04 or PD that received a TE	

The State of Maine WCB cannot accept changes or updates to SROI’s.  The MWCB system does not allow SROI 02 transactions.  If a SROI 02 is sent it will be rejected.
If a denial needs to be amended fax or mail a copy of the amended denial to the Maine WCB.  Clearly indicate at the top of the denial that it is amended and clearly indicate within the denial what is being amended.  Amended denials should be faxed to 207-287-5895 or mailed to WCB, 27 State House Station, Augusta, ME 04333-0027.
Please note that if an amended SROI is sent via fax or mail no other SROI MTC’s will be accepted on that SROI via EDI.  Once a SROI has been amended manually a SROI CO cannot be filed via EDI due to sequencing issues.  The transaction will reject because the Maine WCB system will no longer be able to identify the EDI Denial transaction once a manual change has been made to the denial.

SROI Data Element Conditionals and Business Rules
Business rules that apply to specific data elements are also required when the data element on the table contains the second indicator of “C” or Conditional.  There are two types of conditionals, Mandatory Conditional (MC) and Expected Conditional (EC).  

SROI Mandatory Conditional Data Elements
MC data elements are mandatory data fields if the condition exists in the transaction.  This means that if the condition that is associated with that data element is true, then that field is mandatory.  If the condition is false, then you do not need to provide that data element.  For example, if the claim is for lost time, then the Initial Incapacity Date and Date Employer Had Knowledge of Disability fields must be filled in. If those fields are missing the transaction will reject.
SROI Expected Conditional Data Elements
EC data elements are expected data fields if the condition exists in the transaction.  In other words, if the condition is true, then that data element is an expected field.  If the condition is false, then that data element is not expected.  For example, if the Employer FEIN is different than the Insured FEIN, then the Insured FEIN becomes an expected field in the transaction.  If the Employer and Insured FEIN’s are the same, then the Insured FEIN field is ignored.
FROI and SROI Transaction Testing Requirements
All potential electronic transmission senders must pass testing procedures before the State of Maine Workers’ Compensation Board will accept specified EDI transmissions.  Any transmissions received from an unknown electronic sender will not be accepted even if the transmission itself contains valid information.  The testing process consists of four steps:
1.	Pre-testing Approval
2.	Electronic Format Testing
3.	Even Testing
4.	Test Completion and Approval
1.	Pre-Testing Approval
The potential electronic filing trading partner must submit the following forms before submitting an electronic test file.  These forms can be found on the Maine WCB website.
1.	Trading Partner Transmission Profile
2.	Maine Electronic Trading Partner ID List
3.	Claim Administrator Address List
Trading partners that are in production in other states using IAIABC Claims Release 3 are still required to go through the entire testing process with Maine.  
2.	Electronic Format Testing
The purpose of electronic format testing is to ensure proper file structure when a batch is sent to the Maine WCB.  One transmission batch with a minimum of one FROI in the IAIABC Release 3 format will be required to validate the transmission and ensure proper file structure.  The transmission test batch must consist of at least one header, one trailer and at least one FROI which must pass all Maine WCB data element requirements.  The format test will validate the following items:
•	Transmission method sent
•	Header (HD1)
•	Data Element Format
•	Trailer (TR2)
•	148-proper file length (913 bytes)
•	R21-proper file length, dependent on variable segments
•	Transmission method received-trading partner receipt of AKC    
•	Batch format of files sent is correct
•	Valid formatted data for all data fields
Maine will return an AKC record for each of the FROI transmission test filings.  The AKC record will contain transmission status.  There are three statuses that can appear on the AKC record, a TA, TE and TR.  A TA indicates that the transaction was totally accepted.  A TE indicates that a transaction was accepted with errors and a TR indicates that the transaction was totally rejected.  The electronic format test must result in a TA in order to move on to the next step of the testing process.
3.	Event Testing
After the format test has been approved, the sender must initially submit a batch with at least five FROI 00 filings.  Each FROI electronic submission must pass all event and data element requirements, which can be found on the WCB website.  When the FROI event test is completed the trading partner will be able to file the following MTC’s successfully:

Report Type and MTC	Description	
FROI 00	Original FROI	
FROI 01	Cancel FROI	
FROI 02	Change/Update FROI	
FROI 04	Original FROI and Full Denial	
FROI CO	Correction to FROI	
FROI UR	Upon Request	
SROI 04	Full Denial – FROI previously accepted by Board	
SROI PD	Partial Denial – FROI previously accepted by Board	

The event testing requires a minimum of 3 test files.  

The first test batch must include a minimum of 5 FROI 00 transactions.  On one of those FROI transactions and expected field must be left out of the transaction to trigger a TE.

A TA must be received on 4 of the FROI 00 transactions and 1 TE in order to send the second batch.  If any TR’s are received in the first test batch, those transactions must be fixed and resent before moving on.

The second test batch must include a FROI 01 (cancel a FROI), a FROI 02 (updating any element), a FROI CO (correcting the TE received in batch 1) and a FROI UR (a Jurisdiction Claim Number must be obtained by the MWCB for this transaction).

All transactions in the second test batch must receive a TA.  If any transaction receives a TR or TE, the errors must be corrected and the transactions must be resent before moving on to the final test batch file.

The third and final test batch must include a SROI 04 (a Jurisdiction Claim Number is mandatory), SROI PD (a Jurisdiction Claim Number is mandatory) and a FROI 04(do not include a Jurisdiction Claim Number; one will be assigned upon receipt of a TE or TA).

If any TR’s or TE’s are received in the third test batch, the errors must be corrected and resent.  A TA is required on all transactions.  

4.	Test Completion and Approval
When the event testing has been successfully completed and all transactions have received a TA contact the MWCB for production approval.  After being approved for production status the file naming convention will change slightly; the file name for production claims files starts with ‘FR’ rather than ‘SR’.  The rest of the file name structure will remain the same.  It is also important to remember to change DN104 (Test/Production indicator) located in the header record to a ‘P’ in order for the files to be processed as production files.

Other Information
Other useful information such as population restrictions, value table, technical rules and business scenarios can be found on the WCB website.  You will also find a link for frequently asked questions regarding FROI’s and SROI’s and a master list of errors, which includes WCB and IAIABC error numbers, DN’s and IAIABC and WCB descriptions of the errors. The Element Requirement Table, Edit Matrix and Event Table are available on the Maine WCB website as well.

Glossary
