The correct answer is: E codes

In ICD-9-CM, external causes of injury and poisoning are classified under the E codes. These codes provide information on the circumstances surrounding an injury, such as where and how it occurred.

The other options listed are not specifically designated for external causes of injury and poisoning in ICD-9-CM.
