  • Alert physicians
  • Train staff
    Make sure all staff involved in documentation, coding and billing are aware of these changes and adjust as necessary. Review the changes with them and note any processes that need to be updated.
  • Assure that software is up to date for these changes
    Check with your software vendors to ensure they have incorporated the new ICD-10-CM codes in your products. Test the products by entering the new codes and see if they work. If your software has not been updated, contact your vendor immediately to get the updates.
  • Review any instructions from health plans
    Individual health plans may have updated their coverage and billing guidelines to take these new codes into account.
  • Monitor for future changes
    Remember that there are coding changes every year, so keep up to date. There may be new codes issued during the year, as well as the major change each Oct. 1.
