Medicare EDI

Currently, WPS Insurance Corporation is the Medicare Part B Carrier for the states of Illinois, Michigan, Minnesota and Wisconsin. Recently, WPS was selected as the Medicare Administrative Contractor (MAC) for Jurisdiction 5, which includes Parts A/B for the states of Iowa, Kansas, Missouri, and Nebraska.

WPS Medicare and the Mutual of Omaha Medicare division, both long-time leaders in the processing of Medicare
claims on behalf of the federal government, have integrated under the WPS Medicare banner to administer Part A and
Part B Medicare claims.

What does this mean for our Medicare EDI trading partners? In order to prepare for a smooth transition to the New MAC J5, we have provided a list below with the transition dates for providers in each state. Beginning on the specified date, all of your EDI transactions will need to be conducted with WPS.
