When a provider receives a Comprehensive Error Rate Testing (CERT) error for insufficient documentation, it means that elements of the medical record that are imperative for Medicare payment are missing from the medical record sent in to the CERT contractor for review. Here are some tips to prevent this error:

  • Ensure the correct CPT/HCPCS code is used, if applicable
  • Ensure physician orders and documents the interventions were performed
  • Include test results and lab results, if applicable
  • Make sure the copy sent to the CERT contractor is legible
  • Number the pages before making a copy, so it will be easy to see if one of the pages are missing
  • Use a checklist to ensure all the essential pieces are included in the record
