About ICD-10 CM Diagnosis Codes

Updated code set effective 10-1-15

If you choose to submit ICD (International Classification of Diseases) clinical modification (CM) diagnosis codes on claims, please be sure to follow these guidelines:

  • Use ICD-09 CM codes for dates of services 9-30-2015 or earlier.
  • Use ICD-10 CM codes for dates of service on and after 10-1-2015.
  • Use only either ICD-9 or ICD-10 per claim.
  • Go electronic! Transmit claims using our “Submit Claim” tool (simply register for your free online account) or through a clearinghouse. The ICD codes included in your electronic claim will automatically be validated upon submission.
