Common questions
How do these codes differ from the cause-of-death codes in other ICD-10 chapters?+
Other chapters code the underlying disease or injury type, while Chapter XX codes the external circumstance, such as a fall, transport collision, or assault, giving public health agencies the mechanism behind an injury death.
Why do forensic pathologists care about ICD-10 external cause codes?+
Death certificates feed national mortality statistics, so accurate V01-Y98 coding by the certifying pathologist determines whether injury surveillance systems correctly track trends such as road deaths or occupational fatalities.
