Oregon Workers' Compensation Division Proof of Coverage EDI Transmission Profile is a set of standards used to electronically exchange information between employers and the Oregon Workers' Compensation Division (CD). The profile is designed to allow employers to electronically submit proof of coverage information to the CD in a secure and efficient manner. There are two types of Oregon Workers' Compensation Division Proof of Coverage EDI Transmission Profile: the ANSI X12 834 EDI Transaction Profile and the 837 EDI Transaction Profile. The ANSI X12 834 EDI Transaction Profile is used to submit proof of coverage information for new and renewed policies, as well as terminate policies that have been cancelled or expired. The 837 EDI Transaction Profile is used to submit proof of coverage information for policies that have been amended or modified. Both profiles use the same data elements, but differ in terms of the format of the data.
