Paperless updates for Michigan Medicaid

Key letters and documents going paperless June 2

Effective June 2, 2023, we will no longer mail a number of key medical claim-related letters and documents for most1 UnitedHealthcare Community Plan (Medicaid) plans in Michigan. Instead, network medical health care professionals and facilities will be able to view these letters 24/7 through several digital options:

  UnitedHealthcare Provider Portal      
Letter/document type Document Library Trackit Direct Connect Application Programming Interface (API) Electronic Data Interchange (EDI) Optum Pay
Appeal decision letters X X N/A X N/A N/A
Overpayment letters sent2 X N/A X X N/A N/A
Prior authorization and clinical letters X X N/A X N/A N/A
Provider remittance advice (PRAs)3 X N/A N/A N/A X X

Please share these changes and new digital workflow options with those who are affected, including outside vendors such as revenue cycle management companies.
