Question: ICD-9-CM External Cause of Injury Codes (E-Codes) are no longer used. What ICD- 10-CM codes have replaced them?

Answer: Previously, if a patient had an ICD-9-CM Injury code (800- 904.9 or 910-995.89 EXCEPT 995.60-995.69) an E-Code would be used to describe the cause, intent and activity associated with the injury or poisoning. In ICD-10-CM, the S-Codes and T-Codes are used for coding injuries and poisonings and V-Codes, W-Codes, X-Codes and Y-Codes are used for cause.
