Submission Requirements

All policy data must be submitted to WCRIBMA electronically. Options for creating a policy data submission file include electronic files and online entry.

Electronic files - When reporting policy data using electronic files, data must be formatted using the standard WCPOLS record layouts. All electronic file submissions must include a transmittal record. The WCPOLS record layouts, submission file requirements and transmittal record layout are found in the WCIO Data Specifications Manual. Electronic files must be submitted via the ACCCT Compensation Data Exchange (CDX).

Online entry – Currently, two submission options are available for online entry of policy data:

  • Manage Policy - A web based application accessible through the SOSA Area of WCRIBMA’s website. Manage Policy submits policy data directly into the WCRIBMA’s system.

  • PEEP - A web based application accessible through the ACCCT website, PEEP creates an electronic file that must be submitted via CDX.

    • Information relating to PEEP is available on the ACCCT website. Questions relating to PEEP should be addressed to Deborah Dohl at 617-646-7538 (or

Policy Data Editing

All policy data submissions received at the WCRIBMA are subject to editing to evaluate the reported data for timeliness, accuracy, completeness, and reasonability. Some edits fail as the result of errors in data submission, while others are the result of atypical circumstances. Some edits allow the acceptance of policies with warnings or errors. Other edits call for the rejection of a submission or a transaction within a submission. Failed edits generally require the resubmission of corrected data. In some situations, for example atypical data, explanations may be approved.

Policy Edits

Edit Notification

Data reporters are made aware of failed edits for a submission or policy via:

  • Email Notice from WCRIBMA (as needed)

    Email notifications from WCRIBMA will be sent to Data Reporters, as needed, for situations that are not handled by the Error Reports product.

Edit Explanations

Data reporters may send edit explanations to explain atypical data. All explanations must adequately explain the reason for the edit failure and are subject to WCRIBMA approval.

If an "Explain" link is displayed with the edit, explanations should be sent by using the Explanation Capture System. Refer to the Explanation Capture System User Guide.

If an "Explain" link is not provided with the edit, explanations can be sent via email (

Note that explanations for rejection edits, generally, are not acceptable.
