Medicaid Provider Enrollment – IMPACT Update for MCO Credentialing                                                                                    

As part of the new Medicaid MCO contract HFS will be using IMPACT information to credential providers during the Medicaid provider enrollment and update process.  This will replace the prior credentialing required by each Medicaid Managed Care Plan in Illinois.  You may have already noticed a new question during the IMPACT enrollment of a provider.  The new question is located on the enrollment checklist inquiring the status of the provider’s liability insurance and policy coverage limit insurance.  Bureau of Primary Health Care suggests deemed providers respond to the question as follows:                                                                                                                                     

Name of Insurer:                                                                         

Health Resources and Service Administration (HRSA)                                                                                           

5600 Fishers Lane, Rockville, MD 20852                                                                                                                 

Coverage Amount:                                                                      

No Cap                                                                                                                                                                            


HFS plans to add a question about office hour information to IMPACT enrollments in March.  In the interim, MCOs are expected to collect information on their provider networks as well as provider hospital affiliations.
