Summary
Wisconsin Medicaid has established a formal notification process to inform trading partners (billing providers and clearinghouses) when changes are made to companion documents for HIPAA-mandated electronic transactions. The state will notify partners through website postings, banner messages on reports, and email alerts to prevent transaction processing failures.
Action Required
Immediately: Billing team and clearinghouse partners should ensure Wisconsin Medicaid has current email addresses on file to receive notifications. Monitor the Wisconsin Medicaid website weekly at www.dhfs.state.wi.us/medicaid/ for companion document updates. Check revision logs in updated documents and implement changes promptly to prevent claim denials or processing errors. Contact EDI helpdesk at (608) 221-9036 for questions.
