To begin receiving WCCPAP files instead of hard copy MCPAP worksheets, the carrier can provide a list to MWCIA of every carrier in the carrier group that should be included in the WCCPAP file. MWCIA will then trigger production of WCCPAP files for those carriers. Hard copy MCPAP worksheets will no longer be provided to the carrier once WCCPAP is turned on.

MWCIA utilizes the CDX system to send WCCPAP files to carriers. Carriers can work with their CDX Insurer Primary Administrator (or a user with admin privileges) and/or their IT department to set up a Location in CDX to receive the files. The files will also be available for manual download from the CDX ETR area, and anyone with ETR privileges can access them for up to a month.
