Summary
Maryland Medicaid clarifies that providers must use the Eligibility Verification System (EVS) to verify patient eligibility and MCO enrollment before providing services. The policy addresses retroactive cancellations/disenrollments and emphasizes that EVS verification ensures MCO payment to providers.
Action Required
Immediately: All staff must call EVS at 410-333-3020 or 1-800-492-2134 before providing services to HealthChoice recipients to verify eligibility and MCO enrollment.
