Summary
Pennsylvania Medical Assistance (Medicaid) is replacing local procedure codes W0979, W9068, and W9077 with national HIPAA-compliant codes for case management services. Services rendered before November 1, 2005 must use old local codes, while services on/after November 1, 2005 must use the new national codes with appropriate modifiers.
Action Required
Before November 1, 2005: Case management providers must update billing systems to use new national procedure codes and modifiers instead of local codes W0979, W9068, and W9077. Reference the attached crosswalk document to identify correct national code and modifier combinations. Failure to use appropriate national codes will result in claim denials or inappropriate payments.
