Excludes1 (not coded here)
An Excludes1 note is a pure exclusion: the excluded condition and this code should never be reported together, because the two conditions cannot occur at the same time (e.g. a congenital form vs. an acquired form of the same disease).
- drug or chemical induced diabetes mellitus (E09.-)
- gestational diabetes (O24.4-)
- neonatal diabetes mellitus (P70.2)
