Those are causes of death.

ICD-10 has X85 "Assault by drugs, medicaments and biological substances" and X99 "Assault by sharp object". [1]

But it is unprecedented (AFAIK) to specify an external cause that is so far removed from the point of death.

E.g. assuredly people have died from the long-term effects of tanning, but "sun tan" is not considered to be a cause of a death.
