Medical Transportation Code Conversion Table Updates

May 6, 2016

The Medical Transportation Code Conversion Table, which initially published in the March 2016 Medi-Cal Update, has been updated. Ambulance services (HCPCS codes A0426 and A0428) may not be billed with modifiers DS and QN for a dry run service. Several articles containing links to the Medical Transportation Code Conversion Table have also been updated on the HIPAA: Code Conversions Web page of the Medi-Cal website:

  • HIPAA: Medical Transportation Code Conversion (FAQs)
  • Medical Transportation Code Conversion Notice
  • Medical Transportation Code Conversion: TAR/SAR Policy Update

Note:  Updates within the Medical Transportation Code Conversion Table document are noted with underlined and bolded text. Pages receiving updates reflect a corresponding month and year in the footer.
