Definition:

The ICD-9-CM code for the external cause of an injury or poisoning. Hospitals should complete this item whenever there is a diagnosis of an injury, poisoning, or adverse effect. The priorities for recording an External Code (E-Code) are: (1) principal diagnosis of an injury or poisoning, (2) other diagnosis of an injury, poisoning, or adverse effect directly related to the principal diagnosis, and (3) other diagnosis with an external cause.

Only the first E-Code should be recorded in this item. Additional E-Codes can be reported in the Other Diagnosis field. Present on Admission Indicator would not apply; this Qualifier would be reported with the code for the injury itself, not with its external cause.

Codes and Values:

  1. Must be a valid ICD-9-CM "E" code. To be valid, the code must be entered at the most specific level classified in the ICD-9-CM Tabular List. Three-digit codes further divided to the four-digit level must be entered using all four digits plus the prefix letter "E". Failure to enter the prefix "E" and all required digits will cause the record to reject.

  2. Must include the prefix letter "E" and all digits entered exactly as shown in the ICD-9-CM coding reference.

  3. E-Code ranges E849.0-E849.9 and E930.0-E949.9 are invalid.

  4. If this field is not applicable it must be blank.

Example: HI*BK:63491*BJ:63491*BN:E8802*BN:E8498~

Edit Applications:

  1. A valid entry is required in this field when either the Principal/Primary Diagnosis Code or Other Diagnosis Code 1-14 reported are in the range 800.00-999.99 unless listed as an exception in Appendix N.

  2. When an External Cause-of-Injury Code in the range of E850.0-E869.9 or E880.0-E928.9 is reported, then a Place-of-Injury Code must also be reported.
