Has DCH developed a crosswalk to determine what national codes will replace the nonstandard Michigan local procedure codes?
Since mid 2001, DCH has been notifying providers of crosswalks from local procedure codes to national codes. Providers are notified by Bulletins and/or Numbered Letters at least 30 days in advance of any coding change. This is an ongoing process which will continue until all local codes are crosswalked to national codes. As more crosswalks are finalized, providers will be notified by Bulletin or Letter and posted on the website. All local Michigan Medicaid codes will be eliminated in time to be compliant with HIPAA. Providers will use only national standard codes for any service provided on or after October 16, 2003. Keep in mind however that even though a service may be billed after October 16, 2003, a local code may be continue to be required if the date of service is prior to HIPAA implementation.
