State of Maine
Workers’ Compensation Board
Proof of Coverage

Effective August 22, 2009, the State of Maine Workers’ Compensation Board (WCB) will no longer accept the paper WCB-1A as a form of filing Proof of Coverage. All Proof of Coverage notifications must be sent via EDI using the IAIABC Standards Proof of Coverage (POC) Release 2.1. Any WCB1-A forms received will not be updated in the Workers' Compensation database.

Every entity sending electronic POC records must complete the necessary Trading Partner Profile documents prior to any testing.  

You must go through the testing process before going into production. Please see the Maine POC EDI Implementation Guide for event testing information. Please contact Venessa Williams with any questions about the testing process by phone at 207-287-7197 or by e-mail at

The POC Element Requirement Table contains all of the data elements that the Maine Workers' Compensation Board accepts. This table will also lay out the severity of each element for each triplicate code. You will also find conditional requirements in this table.

The POC Event Table will provide trigger criteria for each triplicate code. The table will also provide the timelines for when each type of transaction should be sent based on the event that is being triggered.

The POC Edit Matirix Table is a table which includes applied editing based on the IAIABC standards and Maine's POC data requirements.

Please direct any questions or comments to Paul Fortier by e-mail at or by phone at 207-287-3818.
