Summary
Maryland Medicaid will begin reimbursing Emergency Service Transporters $150 for alternative destination transports (to urgent care/FQHC instead of ED) and treatment-in-place services starting January 1, 2023. New billing codes A0427 and A0998 are introduced with specific modifier requirements for these services.
Action Required
Before January 1, 2023: Emergency Service Transporters must update billing systems to support HCPCS codes A0427 (for alternative destination transport and treatment-in-place) and A0998 (for Mobile Integrated Health services) with appropriate origin and destination modifiers. Train billing staff on new modifier combinations including destination modifier F (FQHC), U (Urgent Care), and W (Treatment in Place). Verify MIEMSS approval before billing A0998 code. Claims without proper modifiers will not be reimbursed.
