External cause (ICD-10-AM)
Representational Attributes
Permissible Values


A valid 3rd edition code, representing cause of injury, poisoning and other adverse effect, from the corporate reference data system (CRDS) ICD-10-AM data set maintained by Statistical Standards and Strategies, Health Statistics Unit.
Supplementary Values


Collection and Usage Attributes
This code must be used in conjunction with an injury or poisoning code and can be used with other disease codes. The external cause should be coded to the complete ICD-10-AM classification.

An external cause code should be sequenced following the related injury or poisoning code, or following the group of codes, if more than one injury or condition has resulted from this external cause. Provision should be made to record more than one external cause if appropriate.

External cause codes in the range V01 to Y89 must be accompanied by a place of occurrence code.

External cause codes V01 to Y34 must be accompanied by an activity code.
Must be a valid ICD-10-AM 3rd edition code.
ICD-10-AM codes are validated against a number of national and state edits (e.g. age, sex, cannot be PD, rare, comb, CPoA, etc) to improve coding quality.
Queensland Hospital Admitted Patient Data Collection (QHAPDC):
An external cause code may be used in conjunction with any diagnosis code in ICD-10-AM but must be used with codes from S00-T98 and Z04.1-Z04.5 and for complications and abnormal reactions, which are classified outside the injury chapter (S00-T98).

If the principal diagnosis requires an external cause code(s) the external cause code(s) should be sequenced directly after the principal diagnosis then followed by other diagnosis code(s).

An external cause code(s) that relates to other (additional) diagnosis codes should be reported following the last of the other diagnosis codes that it relates to, even if that external cause code is the same as the one that relates to the principal diagnosis.

Additionally, diagnosis codes requiring morphology codes are sequenced directly after diagnosis codes requiring external cause codes.

All other diagnosis codes that do not require an external cause code(s) or require a morphology code(s) should be sequenced after all codes that do require an external cause code(s) or require a morphology code(s).

Punctuation is excluded in QHAPDC.
Enables categorisation of injury and poisoning according to factors important for injury control. This information is necessary for defining and monitoring injury control targets, injury costing and identifying cases for in-depth research. It is also used as a quality of care indicator of adverse patient outcomes.
